  1. Yes FPGA is a Field Programmable Gate Array. Before I retired I used to use FPGAs in my day job. We were always looking for better ways to secure networks. When we felt it might be possible to compromise our code, we completely re-engineered it and were able to push out the revised code to every deployed device across the world. If we had used an ASIC (Application Specific Intergraded Circuit) this would not have been possible. Moreover, FPGAs interface to the electronics making the hardware element of Linn’s Organic DAC simple compared with the inherent complexity with a Commercial Off The Shelf (COTS) chip. Chord Electronics have a similar hardware design for its Pulse Array DAC. However, Linn DAC architecture is different from that of Chord Electronics. PS Audio is another taking advantage of FPGAs: PS Audio converts PCM to DSD making its hardware design even simpler: PS Audio has upgraded its code and customers were able to take advantage of the improvements. To me, the Linn design looks a marvel of simplicity and that can only be a good thing. The downside of FPGAs are they are noisy blighters. The casework and quality of shielding within the case are very important and I am convinced Linn has put as much thought into this as it has into its FPGA code. All this and modularity within the box. if I carry on with this post I’m going to convince myself I need one.
  2. Quite deliberately Brian Eno chose his own hi-fi system to be of average quality so he can check-out his studio tapes on the sort of system most people will be listening to the final product on. His monitors follow the same philosophy. "The monitors I've found appealing are Lockwood's with Tannoy Reds. I find a lot of the newer monitors with horns and whatever are very exciting to listen to but are also very tiring when you have to monitor on them for ten hours a day." Brian also likes Eclipse single driver loudspeakers “I first heard these speakers in Mostar, (Bosnia) playing a record that I helped to produce, so I was quite familiar with the music on the record. What impressed me more than anything else was how tight the bass was and how absolutely accurate it seemed. There was no hang over of the bass. It seemed very sharp, very short. The bass drum sounded fantastic. In fact I pulled the drummer of the band, who had played in the record I produced, in to listen. He said, 'I've never heard a bass drum sound like that on a recording. There is something about the very high speed [response to sound reinforcement] of those speakers. I guess, because they're small speakers; they move very fast and they damp [finish moving] very quickly as well. That seems to be an important part of the sound. The operating principle seems to me to be excellent. It's a completely new idea as far as I can tell in speaker technology and, having listened to them for a little while, I am extremely impressed by their potential. They are also very accurate in getting close to the real sound image and the actual positioning of each instrument. It is a new principle; a different kind of idea from other speakers and, I suppose, it's the beginning of a new road towards a new way of listening to sound. One thing I like is they are not in speaker boxes. I am sick of boxes. I like the fact this is a beautiful shape and it looks like something from this century, the 21st century, not from the last century and it sounds like something from this century as well” I have a MDSM in my bedroom with Eclipse TD510s and the result is very good. I bought the speakers some time ago. I would be dubious of recommending them as the price for a new pair is more than double what I paid.
  3. I moved from a Naim system (NAC282-SC/NAP200) to a Linn system (ADSM/KCT). i much prefer the Linn system because it sounds more natural and accurate to me. The Linn is fuss free compared with the Naim. I use an inexpensive Sony Universal Digital Transport with my ADSM so I can play almost any disc through the system. i cannot comment on the ADSM’s phono stage as I use a Linn Urika II. I had been using a Naim SuperLine and moving to the Linn phono stage was a massive improvement. The Linn is again very easy to set up, whereas the Naim requires the use of plug in resistors and capacitors. Technically I would say the Linn has a (much) better DAC than the Naim and it has Space Optimisation, which does a superb job of eliminating the effects of my less than ideal shaped lounge. I also prefer Linn’s very quiet power supplies totge rather noisy ones Naim uses. There are no doubt those that prefer the Naim sound so I’d strongly advise a comparative audition and many of the points I have raised would not apply to a one box Naim system. Indeed, i once owned a Nait 5i and really liked it: my mistake was going to a Naim multi-box system that simply didn’t work well for me. I am very happy I made the switch.
  4. The late John Peel who helped launch the careers of many bands used to listen to music on a lo-fi system. He's reasoning was most folk would listen to his show on a less than perfect transistor radio and he wanted to make sure the sound quality was adequate for his entire audience to enjoy his shows. Back in 1983, Kate Bush's `The Dreaming' was digitally mastered to provide the sound she wanted. Kate was interested in production techniques and produced the album herself. Shortly after it was done, Linn approached Kate. Having heard about Kate's production interests, Linn felt it was time to demonstrate the superiority of properly handled analogue recording. Linn said Kate was mighty impressed by their analogue-vs-digital demo, but Kate said: "I wouldn't say I was necessarily impressed by their demonstration, but yes, I feel there's an awful lot in analogue recording. We had a lot of problems working with digital for `The Dreaming' which was digitally mixed. Editing was the main one -- it was so time-consuming. Some things obviously were easier working digitally -- otherwise we wouldn't have used it. But the vast majority I reckon would have been easier on tape. Particularly as I was working with people who'd worked with tape all their life. In the end we brought in a guy who was familiar with digital equipment from classical recordings he'd worked on. And it didn't take very long after that. The problems rather put me off digital. We all felt a kind of alienation from the process of creation using it. There's something reassuring about a tape that you can see and touch. You've more trust in it somehow. There was a feeling of uneasiness about using digital that stemmed from the fact that we felt it wasn't as easy to use in many respects as tape is." Apparently Kate listens to her music through a Naim system. Though I did read Paul Simon uses a Linn system or, at least, has an LP12.
  5. Although my music collection is heavily weighted towards the 60s and 70s, I agree there have been some great release this century. I’m not familiar with the albums you list, but I shall try to have a listen to some of them. I would suggest albums by Basia Bulat (Oh My Darling), Kate Rusby (Ghost), Karine Polwart (This Earthly Spell), The Eccentronic Research Council (1612 Underture) and Public Service Broadcasting (The Race For Space). There are, of course, last century bands still making great albums such as Van Der Graaf Generator’s Trisector and Grounding in Numbers, Half Man Half Biscuit’s - well everything they’ve done really - Eddy Grant’s Reparation and Scott Walker’s The Drift. I’m sure there is more … I think Peter Hammill must have written this song with me or someone just like me in mind
  6. Thank you for the detailed and very useful post. It is interesting to know Qobuz has copies of these albums too. My shelves are fairly full and I keep saying this will be my last box set and then another compelling collection comes along. During lockdown I bought sets by Colosseum, Barbara Thompson, Gong and Steve Hillage as well as VDGG’s Aerosol Grey Machine box and the vinyl rereleases from Peter Hammill and the K Group. I also bought the complete Nirvana vinyl box set (the Uk band from the 1960s, not the 90s band from US) and I’m delighted with them all. The last set I bought before VDDG’s Charisma Years was by Caravan. I wonder if a Qobuz subscription would cure me from my box addiction. Perhaps after the Let It Be box set arrives it would be good to stop.
  7. You do not need special cables. As you need 20 feet, my choice would be Canare LV77S. https://www.bluejeanscable.com/store/shopbycable/LV77S.htm Alternatively, I would go for https://www.markgrantcables.co.uk/uk/audio-cables/mark-grant-hdx1-pure-copper-audio-cables/ If I can’t get appropriate Linn cables then Canare is my cable of choice. With non-Linn, I always opt for Canare, I figured if they are good enough for Abbey Road then they are fine for me. You can buy very expensive audiophile cables that may sound as good as Canare or possibly cheaper cables that equal them (I have never been lucky enough to find those ones). The caveat is I don’t have your setup, but can’t think of any reason Canare would not work well.
  8. I would load a trial copy of JRiver Media Centre (lasts 30 days) - use the import option under tools and import the folder holding the music (this can be on a stick) - under Tools > Options turn on the Media Server - you should now be able to select Music in the Linn App or Kazoo to play on the MDSM/2 JRiver MC is the one I use, but any DLNA or UPnP software should work. My assumption is a trial licence has never been used and expired on the laptop previously.

Indeed the errors may not be there in the non-CD version. As I can't hear them when I play them it is of no real consequence except knowing they exist on my rip is .... FWIW Apple Music with error checking rips the disc as if were perfect
  10. Italian prices seem about the same as UK prices. Sorry, I know nothing about Spotify. I avoided it after a friend had a strange problem when his daughter’s iPhone started to play music on his hifi even though she does not live in the same town. Apparently Spotify Connect is designed to work on either local wifi or the Internet. This feature was enough for me not to want to use Spotify.
  11. This is a fantastic set with a superb book and 3 BluRays. I have all the Van Der Graaf Generator, Peter Hammill, Chris Judge Smith and Hugh Banton albums I know of on my music server, but am still very happy to have this new set. I, too, wish it had been a vinyl release. The new mixes are wonderful. Does Qobuz have the originals and remixes? Did every CD rip accurately? I found some inconsistencies on the Rimini live CD last track. It plays without problems in my CD player, but XLD reported errors, Did you rip the BluRays? i also bought the Caravan box set, Who Do You Think We Are, which was also very good, but XLD reported similar problems on CDs that lasted longer than 70 minutes. They all play fine. it is probably true I am crazy to continue buying these box sets, but we’re never going to survive unless we are a little crazy.
  12. They used to say in the computing industry that nobody was ever sacked for buying IBM (whatever happened to IBM - never hear of them these days). I would say nobody who loves music is ever disappointed by buying Linn. This forum is independent from Linn and enables us to exchange views, I think that is a good thing.
  13. If Linn is carrying out market research to prioritise its product development then I don’t see this as bad thing. I have no problem in Linn knowing why I bought its products and what alerted me to them. However, I have a huge problem with a company like Google knowing anything about me; I do not use its search engine or other products and do my best to block its analytics, but I think it’s a losing battle - big brother is watch me and everyone else. I buy hifi electronics predominately from 2 companies I respect: one of those being Linn. So I am naturally interested to read about any new developments they are working on. I probably miss out on some good products from others that I simply do not explore. Irrespective of how good a turntable or phono stage is from another company I’m unlikely to consider it. However, If Linn brought out a direct drive turntable, a strain gauge cartridge I would definitely like to hear it. This is also true of the Karousel and NGKDSM, which I’m sure I’ll listen to one day. I probably approach buying music in a similar vein. Showing little enthusiasm to explore new artists, but I still look forward to every new release or remix by my favourites. Some of my music purchases are bizarre though: what was I expecting to find in Scott Walker’s pre-Walker Bothers recordings? My favourite Scott LP being Tilt.
  14. I had a Nottingham Analogue Space Deck for a good few years. i got fed up with the turntable and its idiosyncrasies, but I really liked its Unipivot Arm. I have no idea if it is practical to fit an Ace Space Arm to the LP12, but if it were then it might be worth a look. I did look at Naim ARO when I went for my current LP12 but preferred the Ekos SE. I thought the ARO uncomfortable to use and the Ekos SE sounded better. The Ace Space Arm had a superb build and I felt very comfortable using it.
  15. If my memory serves me well, when the LP12 first appeared its main rivals seemed to be the Ariston RD11, Fons CQ30 and ERA MK 6. I don’t recall much about the Thorens at the time. I ended up buying a Garrard Zero 100S - well we all make mistakes and paying £75 for a turntable, arm and cartridge was a bit unnecessary as all a TT had to do was go arounds at the right speed without wow or flutter or rumble. Now, where did I put my strain gauge cartridge.
  16. Is there a reason Qobuz is $129 in US and £129 (about $180) in UK? - might be VAT and some other tax, but superficially it looks like UK customers have to pay a premium. Though it is comparable with Apple Music at £10 a month and £8 a month for Amazon Prime members. I’m not criticising the Qobuz pricing and agree it is not a huge a ount to pay: simply trying to understand it. I hope music streaming services are better than the BBC. My mother has an older iPad and now all she gets from the BBC, a service we are obliged to pay for irrespective of whether we want it, is a demand to upgrade to the latest apps: an impossibility without buying a new iPad. The ITV app is the same, but good old Sky still has an app that works on older platforms. if I were to use a streaming service then I think I would feel more confident with the longevity and catalogues of Apple or Amazon though I prefer the download direct model where more money goes to the artist. That said does an artist on an independent label have a higher income than one who has signed up to one of the majors?
  17. @Chris 1970Certainly MinimServer and JRiver can access music across multiple folders and in MacOS a disk is just another folder. I have two old Mac minis - one for general stuff and one for music, if I access the Thunderbolt Attached Storage (TAS) on my Music Mac mini from my Office Mac mini then it appears as /Volumes/DJB (I called it DJB as it's my digital juke box) and my second disk shows up as /Volumes/DJBXtra so the software has no idea my music is stored on two disks attached to another device across a network. So Roon should work no problem just as the two programs I have used do. As @MickC says above. If for any reason it doesn't index across folders then we can overcome this using symbolic links. Make a directory called Music and make aliases for /Volumes/DJB and /Volumes/DJBXtra in the Music folder. The software won't care if they are HDD or SDD or a mixture. I'm 99% sure Roon won't need such jiggery pokery. Originally I had my Thunderbolt Attached Storage, which is a WD Duo, set up as RAID 1 with mirroring, but when I exceeded its capacity, I split it into two separate disks, just a bunch of disks (JBOD), and restored from backup copying half my music files to one disk and half to the other. I reindexed and it all worked. So you can add disks at a later stage. I'm not sure how is easy it is to add things inside the chassis of a new Mac mini, but adding thunderbolt attached storage is no problem. Operationally, it will work very quickly. I would be cautious with ultrafast M.2 PCIe NVME SSD storage as I'm not sure the Mac's thunderbolt ports can handle all of these, but with normal SSD you should move data at around 2.5 GB per second, which is much faster than the internal SSD in my 2012 Mac mini. So will multiple plugged in SSDs work? Yes they will.
  18. My preference is to download direct from the artist and wish that was the prevalent model. Or buy a CD direct from the artist. Bandcamp and Burning Shed p are a good way to buy in my opinion. if you buy a second hand CD from a charity shop then does the artist benefit at all? Marie Lloyd disliked the phonograph as she thought recording her would be the death of the music halls, which is where she earned her money.
  19. The situation is not as bad as it first seems. I suspect NetGear Armour sees Password in the URL and thinks “Danger”. The URL containing the credentials given by OP result in status":"error","code":401,"message":"Invalid username\/email and password combination" However, it would need somebody with a Qobuz account to see if replaying his or her string got further. The password probably combined iwith a salt and hashed with something like bcrypt.. If this is the case and the attempt to replay it gets nowhere then it’s safe enough. It was be nice if the authentication between DS and Qobuz was encrypted and hopefully that wiill happen. I would further suggest that the motivation for a hacker to invest his or her time and energy into breaking in to one Qobuz account is not very high.
  20. When I rip CDs or download music then I often end up splitting it up. Let's say the album is "We Are Ever So Clean" by Blossom Toes, which came out in 1967 and had 15 tracks. The CD version has 25 tracks. So I ended up with the original album, a second album of 9 assorted tracks and the non-album single "I'll Be Your Baby Tonight" with flip side being "Love Is", which is on the original album (so I duplicated it). I could do this with Playlists, but I'm stuck in my ways. I hardly ever listen to the additional material or the single (preferring Bob Dylan's original), but often play the original album, which remains one of my favourites from the late 60s. I am definitely one for albums rather than mixed up tracks. I sometimes wonder if I need to keep outtakes especially when the artists themselves say these are poor and thrown out for that very reason, but I find it hard to press the delete key.
  21. @Chris 1970 Thank you for an interesting write up. What Martin Logan speakers are you using? Are you using the Electrostatics or Motion series? I have heard a pair of ElectroMotion ESL X (driven by Chord amps) and was very impressed. I doubt I could accommodate them though as my cottage is not big enough for panel speakers (I own some Magnepan, but they are in storage at the moment). I have not heard ML Motion series, but know they have a good reputation. Are you using Space Optimisation V2 with your MLs?
  22. I'm assuming the actual credentials reported are yours and you've changed them so you could post here. That would be enough to put me off Qobuz. I guess you're paying for a Qobuz subscription and would prefer nobody to hijack it. What can they do if they know your user name and password? Could they buy downloads or anything else that costs you money? Can they access your Qobuz account details and payment data? Do your Qobuz account details contain any data you'd prefer the world not to know? Do you use your Qobuz credentials (password) for anything else? If you paste this URL in to a web browser what happens? (You may want to change your password after so doing). if your NetGear Orbi's Armor firewall can see your credentials then I would guess any Internet routing device between your Linn and Qobuz can also see and log them. In which case they are compromised. If Linn were encrypting using https then it would encrypt these data before sending them on to your network and your NetGear Orbi's Armor firewall could not see your credentials so it is not doing this. The HTTP specification (Section 15.1.3) says I'm with @petecallaghan. Very interested to hear what the Linn guys say. I'm not familiar with the NetGear Orbi's Armor firewall so there may be some mitigations I'm unaware of.
  23. I have heard Kudos speakers and they were much better active than passive. The only time I have been really impressed is when I heard them in a Linn Exakt system, previously I heard them with Naim and wondered how they had gained so many accolades. Nonetheless, when it came to decision day I opted for passive Spendor D9s and am still convinced I made the best choice. An Akubarik system would have been nice, but a bit too expensive. Choosing the speakers that suit you best in your listening room is personal choice. You have to try them, there’s no other way in my opinion.
  24. The Panasonic is very good, but if you want a Universal Player then there is the Sony UBP-X800M2 4K UHD. I have its predecessor and am very happy with it. It has no on board DAC (no analogue out) and connects to my ADSM through a Blue Jeans HDMI cable and my network with Blue Jeans Cat 5e. Sounds great to me so I can only guess how good it would sound through a NGKDSM/H. The picture quality is fine. Couple of caveats, I don’t have surround sound so can’t say if this is top notch. I hardly ever watch films (maybe one or two a year); it does a great job with remasters of classic UK TV shows (Gerry Anderson, the Prisoner, Red Dwarf etc.), but can’t say how it fares with latest Hollywood blockbusters.
