  1. If I was paying 2 Grand for a Phono stage it had better support a fully balanced input and have load changing via relay switches whilst the device was powered on.
  2. Try Stetsasonic in the 80s or Jurassic 5 for 90s early 00s. I'll grant you a lot of hip-hop is rhythmically driven but then so is a lot of the funk and soul that it sampled. There is a surprising amount of heavy metal and hard rock sampled by rap artists as well. I remember being quite surprised finding a Free sample in the first Blackalicious album and not the most obvious track from Fire and Water to sample either. Early Queen Latifah is melodic as well and thinking about it so was the first Boo Ya TRIBE album as, like Stetsansonic, they also played their own instruments. Early Jazzy Jeff stuff also has a lot of melody to it, yes he of the I used to work with Will Smith fame, in fact the album was called He's the DJ and I'm the rapper as Jazzy Jeff was actually the bigger star of the two at the time. The early Wu-Tang stuff was based around melodies taken from Hong Kong cinema and still sounds very different to anything else. Like most heavily commercialised music, hip-hop has become very bland these days but the breath control of Rakim from Eric B and Rakim is just incredible even if he is basically just saying how much better he is than anyone else. The Disposable Heros of Hiphopcracy and early Ice T are just pure social commentary following on nicely from Gill Scot Heron and The Revolution Will Not Be Televised.
  3. I am more concerned about the longevity of transports than the sound quality or otherwise. Modern DACS can reclock and reconstruct awful output these days so it is not so much of an issue. The ability of a transport to last multiple years with no skipping and failure to read is what impresses me. Plus being able to read CDs that are not quite perfect, be they scratched or non red book. My Plextor could read almost anything but it was flimsily made and the plastic draw has snapped. Very few transports are made of solid metal parts, even some of the supposedly more expensive ones. Phillips made lots of different grade CD mechs but hardly any high end players ever used the top grade stuff and to be honest they probably didn't need to. My Micromega needs a new rubber belt every 7 years or so and some clean grease but it still works 25 plus years after I bought it but it is very fussy on CD-Rs and would only play certain brands. The Naim Uniti 2 with it's expensive slide out drawer, magnetic puck and perceived build quality stopped reading CDs after about 4 years of not particularly heavy use. These days I am either streaming off hard disk or using the digital out of Fiio DAP playing stuff off Micro SD cards. I wouldn't know what to buy now if I wanted a new Transport. The people behind the old Phillips stuff have started their own company making parts so maybe someone is doing new machines based off them.
  4. I managed to get this working almost a year later. In fact I had 3 CDs I had issues with. One was A-HA the Definitive Singles collection. One was a 2005 pressing of Goldie Lookin Chains' Safe as F*ck and the other was a signed CD-R of Grandmaster Caz's Mid Life Crisis my sister picked up from Grandmaster Caz himself in New York (he is most famous for having his Lyrics stolen to use in the Sugar Hill Gang's Rappers Delight.). An odd mix but we have an eclectic collection in the house. I ended up digging out my old Plextor CD-RW which is a good 18 years old or so. I tried DbPoweramp on a few different modes. By far the technically most interesting CD was the Goldie Lookin Chain one ( I appreciate the audience here won't be a fan of the music). Encoded with duff check digits so it intentionally trigger C2 errors, even if you could rip it it would sound distorted. Using the Defective by Design option for this failed on my inbuilt DVD-RW but worked on the Plextor. The Plextor even showed I had a hidden track on the CD that the other drive had never found nor any CD player I used either. My Micromega won't even recognise it as it cache's the Table of Contents and they did something naughty with that as well. Can't take it back It was bought years ago. Burst mode was enough to get the A-HA CD-FS done when used with the Plextor and the CD-R would rip on burst mode on the Plextor but not on the inbuilt drive. I didn't try Exact Audio Copy with the Plextor on the A-HA or Grandmaster Caz but it could not cope with the GLC album even with the Plextor as the distortion needs the interpolator of the drive to fix it and EAC doesn't have an option for that at the time of writing. Interestingly, the Plextor produced far better C2 error details than the inbuilt drive. Both drives could detect C2 errors but the error message back from the Plextor was far more detailed and useful. The Plextor can also over-read and handle all sorts of odd non-standard CD features. Back in the day it was always recommended to get a Plextor reader and a Yamaha CD writer as the latter could do burning tricks way beyond what was legal in the Red Book standard and could basically copy almost anything. Glad I held onto this piece of kit. To be clear, if a CD is fine, basically any modern reader will make a bit perfect copy. We are now talking about crazy edge cases that are non red book and damaged CDs. Hope this helps someone else.
  5. If it is like the Hugo then the answer is no. It voids the warranty and they use unusual values as the circuit runs at a non standards voltage. You would have to take it apart to do so. It is not designed for the user to do this although anyone with decent DIY skills could do it.
  6. I agree with of lot of what you say Keith but bias can work in different ways. If you are determined that you won't hear a difference it may mean that you actually don't when one exists. Everyone has expectation bias even when they think they don't there are multiple papers on the subject and it is fascinating . My issue with a lot of measurements is that they are often over simplified. Is a worst case distortion of 1% in a frequency range the ear is sensitive to actually better than 5% in an area outside the audible range. A graph at least gives you a bigger picture than a single number value. All of this is somewhat moot with speakers having 10% distortion or more. I like double blind listening tests and they are useful but long term listening is also essential as I have had listening fatigue from certain systems that I enjoyed on the initial 5 minutes. It is also possible to start to differentiate systems more over 30 minute session as you start to pick up the differences. Short demos can be very overwhelming. I continue to find that I can sometimes tell two components apart but I have no preference for either, they are simply different. I usually only pick in terms of clarity which has always coincided with the better measuring of the two components since they have less distortion.
  7. Give Acton-Gate a call in Wrexham. They have repaired stuff for me in the past. If you have car it's just tunnel fare and then M53 and A483 for a bit when you get to Chester. Less than 1 hour from Liverpool.
  8. Who was buying their arms anyway after the doubling of the prices? That cannot have helped sales. They had added thousands to the price of something that has had no improvements done to it based on a sunk development cost from 30 years ago. I like SME arms but they are not worth it now especially since Audio Note worked out how to make a reliable Helius tonearm clone for less than a grand.
  9. Do the Quads comes with the overload protection circuit (clamps) to prevent modern ( solid state ) amps from frying the treble panels? If not I suggest you add them pronto. Arcing a panel is the bane of ESLs. If it happens you will see a spark especially if you turn the lights down. This means the panel now has a hole in it and will need to be replaced/repaired, not cheap and not really a DIY job unless you are very hardcore. Electrostatic panels do age even if not used. The adhesive that bonds the material that holds charge onto the mylar panels does weaken over time, in fact some poeple just rub graphite on directly and this can wear off. A 1970s LP12 will be very euphonic and if you like the sound then any upgrades will make it more accurate but not necessarily sound as good. The Hercules board is a good replacement power supply if you need it and gives easy change from 33 to 45 without a manual adapter. Replace the cartridge if you have no idea what it is and no idea about the state. A Goldring 1024 or similar will do. Do you trust your vinyl to a stylus of dubious history? The flat belt and crowned pulley were something Linn actually did well. Far better than the stupid round belt on the Michell and Transcriptors decks which were only used as they allowed easy changing of the speed originally by moving the belt onto another width pulley. I cannot comment on other source of the belt but Linn's belts are pricey given what they are but then it is hard to machine a decent flat belt. Much easier and cheaper to do a round profile. Sounds like you have the making of an interesting system. Enjoy it.
  10. We have to be careful with terms here as slow can mean different things and have different causes. The delay added by a complete network from start of packet transmission to the reception at the destination is not constant and if you ran monitoring on it you woud get a graph of delay in seconds against the number of packets delayed by this amount. What you hope to get is a bell curve but you often get a bell curve with a smaller spike to the right of the graph. What this shows is most of the time the delay falls with in a certain range but sometimes you get much longer delays. This is not captured properly by the average latency number. For High Frequency trading this is an issue as you can suddenly get a delay that is relatively much bigger than the norm and you can lose money due to this. Same for VOIP wth no buffering or network gaming. In this context you cannot rely on buffering to allow you to smooth out these anomilies. Hi-Fi on the other hand can handle these by buffering so if a packet is late arriving you can kill some time by draining the buffer so the issue largely goes away. If you are getting drop outs and stuttering or stopping then the average delay is too great and I would look at the network in more detail. A network can be slow for a number of reasons: One, the actual hardware is just very slow at routing and sending packets. Anything bought in the last 5 to 10 years should be good enough in this regard for streaming audio. Two, the quality of the network is poor and you have high packet loss and resends, usually this is due to a faulty part or a damaged network cable. They can be almost broken and due to the robustness of tcp/ip you can still send a message through, there will just be a lot retransmission and so things will seem to crawl. Three, the network is saturated. Possibly someone is streaming High Def video or you might even have malware using up your bandwidth. Your packets containing music are stuck in a queue behind the other traffic and may even be dropped so that sending side has to retransmit. It is possible to measure and test for all the above. The main advantages of isolating your hifi set up onto its own switch are that issue three is far less likely and also a degree of security. If you don't stream from the internet but just replay from local storage then it is better not to connect to the outside world as then you don't need to worry about your network being hacked and having patch everything on a regular basis. For the security reason alone I would recommend a separate network for your Storage and Hi-Fi. If packet loss is heavy the NAS and Streamer may decide to change the encoding format used to transmit your music and my transcode it on the fly. If this occurs then you might well be able to notice a difference as you are comparing FLAC with mp3. If this is not the case then the audible effect will be drop outs. TCP packets use check digits so random digital noise like you got with a dirty CD or misaligned DAT tape don't occur.
  11. PM me if you are interested. This is way off topic for a hi-fi forum.
  12. I just read the link NoPiano posted. Wow. Not sure how a switch can improve signal to noise ratio or why standard RJ connectors aren't good enough. Almost all network vendors will let you take kit on trial to evaluate it but I doubt any audiophile brands will. If we could get one on evaluation we could measure it for you. For audio on a home network your 15 quid switch would be more than fine. The improvement over wi-fi is huge and wi-fi is good enough most of the time anyway. The geekiest network thing I have seen is the layout of some of the exablaze network interface cards where one of the chips is at 45 degrees to the rest of the board which is all laid out at right angles otherwise. Why the 45 degress? The asymetric copper tracks, with one longer than the other by 2 cms give a measurable increase in latency ( at the picosecond level ) so they rotated it to make them equal length. This may give you in a win in high frequency trading which every picosecond counts but in hi-fi would be pointless.
  13. Not sure if this is directed at me but I use the above switches at work along with Corvil monitoring (https://www.corvil.com/products) of the packets to ensure accurate latency measuring. I've no idea what an audiophile switch is but I have a lot of experience of Ultra Low latency networking and the various vendors operating in this space. None of this is required for Audio but being able to do a basic measure of the network performance comes in handy.
  14. Page 5 is where it gets interesting. The NAS can change the protocol being used if it detects a slow consumer due to packet drops. In fact this thread is pretty good anyway as you see people arguing why there cannot be a difference until it is proved that there is.
  15. If you want to see if a switch makes a difference then fork out the money for https://www.arista.com/en/products/7130-series (Arista just bought out Metamako) or maybe https://exablaze.com/exalink-fusion Plug it in and see what you think. Apart from you being considerably poorer I highly doubt this will make a difference. Given these devices are currently state of the art for networking ( 10G/40G/100G) then if they don't sound better then nothing will If you are ultra paranoid then measure the latency between each port pairing. Due to the different lengths of wire involved you can find the 2 port pairs with the lowest latency and then use them. The picosecond delay differences are measurable. However I am guessing you are listening to music and not high frequency algo trading in a co-located data centre so none of this matters. If you can avoid using wi-fi then do so as it's a very inefficient way to send packet data and signal strength and other people using the same router can cause problems. Plugging an ethernet cable into the router you have connected to the phone line will be good enough. Audio data ( even hi-res ) isn't actually that much at all and compared to video it is nothing. From an audio point of view you are interested in maximum latency and not average latency and the outliers in a network can be much highter than the average but again you are listening to audio which even at 192Khz sampling frequency isn't going to make any difference. If you can watch iPlayer or Netflix withouth drop outs and buffering that are not caused by your internet supplier but by your own network then you will be fine with just music. If you have a NAS and a Streamer running off a dedicated switch not connected to the internet or the rest of the house then this will increase security and prevent the network being saturated by other people streaming hi-res video across your network.
