  1. All this is about though is the source, and separating the DAC from the computer (the streamer function) within that source. There is good reason to do this as computers are really noisy things so having a DAC stand-alone separately from the streamer (computer) is really sensible. And it allows you to invest in the DAC for the long-term and keep the cheaper computer bit, which is more likely to go wrong and possibly be superceded, separate. It’s only one extra box.
  2. Yes I think the difference is in what designer John Westlake did with isolating the PS and other noise-reducing tweaks.
  3. I have demoed a number of streamers without DAC (network bridge seems to be the term many use). My experiments have determined that the sweet spot is a sub £1000 bridge from someone like Pro-Ject (Stream box S2 Ultra) or SOtM (SMS-200 Neo Ultra) or Stack Audio (Link 2). These all sounded identical to me and identical to a £3k Auralic Aries G1. But they all did sound significantly better than a cheap home-built Pi or a Chromecast Audio (which, I would add, at £25 is still the biggest bargain in Hi-Fi ever). A Hi-Fi buddy compared the micro rendu and the SOtM and found the SOtM better. They are all USB only though. My favourite at the time was the Pro-ject due to its nifty tiny size. However, I then got the SOtM to improve further by adding the SOtM sps500 power supply and the SOtM external clock, but the latter makes it crazy-expensive. Another small uplift came replacing the SOtM sps500 ps with a Sean Jacobs lps. in my view the differences between network bridges are marginal once you get beyond a home made pi, even with the small improvement from external power supplies and external clocks. With a limited budget I’d say you get a much bigger SQ improvement by investing more in a better DAC. In my demo experience moving from a £600 Pro-ject streambox S2 Ultra to a pricey Auralic or SOtM plus PS plus clock will give marginal improvements compared to moving from a £600 DAC to a £4K DAC.
  4. Sorry, double posted in error.
  5. Chris Thomas tested his W8 with a Vitus SIA-025 - great combo. I am surprised that HiFi+ did not put the speaker on the cover. Such a good looking speaker deserves that
  6. Hi Fi News takes so much advertising from one particular hifi distributor that I have noticed that they tend to concentrate on reviewing their products. Hifi News also own Stereophile so I imagine the same there. Hifi World is really old-school and tend to avoid the esoteric brands. Hifi Critic is not online but do have some off-the-wall things occasionally though the people who run it are rather Naim-obsessed. So Hifi+ is the only place for Boenicke. Same with Vitus, the amp brand I personally think are the best, they get little coverage beyond hifi+.
  7. The company behind this product, HFC, do make good speaker cable, they are not a complete con merchant. I demoed one of their speaker cables amogst others, including some top-end black rhodium, a few years ago and it was somewhat better than the other cables. A real detail-grabbing cable.
  8. I played files directly from the Pro-ject StreamBox S2 Ultra (connected via USB to a hard drive), and via Roon to the same Stream Box and could detect absolutely no difference whatsoever between the two. I did the same test using Qobuz (the streamer connects directly) and no difference also.
  9. I demoed the W8 with an SIA025 - it’s a perfect match, the two feel made for each other. Same with the W13 and W5 which I have tried it with. The SIA030 is even more impressive. At shows Sven used to run Trilogy amps - so no surprise that these sound excellent with Boenicke. I ended up driving my W5 with a Trilogy 925 integrated - a fabulous combo.
  10. I take Ethernet out of the router to a Cisco 2960 switch sited next to it, in a room away from any Hi-Fi. From there via an SFP input in the Cisco it takes optical to the ER. I have two systems employing an ER and was running the second system from a second local 2960 switch using the optical socket to deliver to the ER locally. However I have just bought a more recent Cisco 2960 C series switch (they are not much more than the old model) which has two optical inputs and replaces the old Cisco next to the router. So now I can connect both ERs directly back to this single Cisco via two lengths of optical cable and four SFP modules. Hope that makes sense.
  11. I have two systems with an EtherREGEN (ER). One system improved markedly with the ER. it improved particularly the bass resolution, and a pleasant softening of a little digital noise that was causing some grain which manifested itself in things such as sibilance. I was so impressed that I bought an ER for my other system which it also improved but not to the same degree, a more subtle change. I have not tried either ER with an LPS. Interestingly when I installed optical network fibre between each system's Cisco switch (the Cisco 2960 has one optical input) and the ER, the improvement was greater in the same system which experienced the greater improvement from the ER. If your Cisco switch has an optical input/output which most 2960 do have, you should try this, it is literally a £20 experiment. From FS.com each SFP is £6 and you need one at each end, and cable is the same price. Currently I’m experimenting with single mode vs multi mode network cable and SFPs. I can report that within multimode there is no difference between OM1 or OM4 cable. I reckon I’m hearing a small improvement using a 1310nm wavelength SFP driving OS2 single mode fibre compared to the 850nm multi mode fibre. Whether this is due to the higher wavelength SFP or the single-mode fibre I don’t know, or it may be expectation bias as the difference is subtle. Given how cheap the optical gear is it makes experimenting fun. And there is no market in Hi-Fi optical cable, so that’s one less variable to deal with, though there are significant differences in the physics behind the way multi mode and single mode fibre works. I have an external clock plugged into one of the ERs, the one which saw less significant SQ improvement, as I had a spare socket on the clock and spare 75 ohm cable, but disappointingly I do not hear any change between the external clock and using the ER's internal clock. However it is a sine wave clock and apparently the ER likes a square wave. John Swenson, the designer of the ER, published a research paper and noted that a cheap minicircuits low pass filter will convert the signal to a square wave. So I have ordered one, it’s worth a £30 punt to see (Link to John Swenson paper). On that forum there is one thread in the Uptone sponsored area with much discussion re external clocks on an ER (https://audiophilestyle.com/forums/topic/57686-the-etherregen-thread-for-various-network-cable-power-experiences-and-experiments/#comments)
  12. I have tried three. This single mode SFP- https://www.fs.com/uk/products/48929.html This is what I am currently using. And this multi mode- https://www.fs.com/uk/products/22138.html which I tried with OM1 and OM4 cable. The two cables sounded the same. Your SFP is like this one, a multi mode SX. I also tried this multi mode SFP but it did not work with my EtherREGEN, which require 1000 mbps speed - https://www.fs.com/uk/products/23583.html I prefer the single-mode over the multi mode, a little more preciseness to the sound. Though I am not sure if this is the SFP, which is a longer wavelength SFP, or the nature of single mode. But both are better than Ethernet.
  13. Yes I have, and surprisingly it does improve the sound. You do need a Cisco 2940 compatible SFP transceiver module at each end. I have heard people rolling their SFPs and getting changes in SQ, though I have not done this.
  14. I’d be interested in the effect of the Isoacoustic Orea. I have had great success putting my dac on a Townshend seismic platform. You can hear the improvement clearly.
  15. Congratulations Greg! One of the finest speakers in the world.
  16. No you can’t bypass the active bass. The W11 is a passive version of what I think is the same body. I’m not sure why you would want to bypass it? The active bass is incredible with its completely sealed unit.
  17. I like the Supra as it is designed as a subwoofer cable. I can't comment on this Chord cable. Have you tried ringing David? Monday - Friday him or his office always answer the phone even if the email response may be slow this week.
  18. It is not on the website, you have to email MCRU. David, who owns MCRU, can get you anything but you have to request it.
  19. Yes that is the cable. It is available from MCRU who can supply any cable from the Supra range. Great business to deal with too. These cables sound better than the XLR-XLR ones I had before and are one tenth of the price.
  20. I found the Supra blocks from MCRU, complete with the Supra main cable, are very well built, have excellent wall attachments, and offer a degree of filtration which improved the sound of a DAC I run through it. I was so impressed I now have three of them.
  21. I have read a few pages here but I am confused - when this topic comes up on Pink Fish, where I have been more regularly, the objectivists get belligerent: Keith from Purite repeatedly says the same thing ad infinitum, others condescend because they are scientists, anyone spending money on power cables is ridiculed etc etc. From what I have read here it is so friendly and accepting of others views. Even the same people who are rude elsewhere! Is it always peace and harmony? Is this down to strong moderation?
  22. I doubt any of the speakers will be more or less good with your amp as they all have similar sensitivity. I am guessing that your measurements are in feet, I have a pair of W13 in a room 4m x4.5m, not much bigger than yours, with an open plan opening next to one speaker and a bay window next to the other, so that helps with having no close reflective surfaces. They sit around 30 cm away from the 4m wall and sound off the scale in unbelievableness, I mean crazy crazy good. I have a pair of W5s on my desk very close to my window and they also sound phenomenal (picture attached) so I would not worry about not having them in a lot of space. With regards to being in a flat it depends entirely on the sound insulation. Some old mansion blocks in London have amazing sound protection, whereas some converted houses and modern apartment blocks are dreadful. I would expect any floor standing speaker could present an issue in a flat if playing at volume, in fact the W8 is probably the most flat-friendly floor-stander from a neighbours point of view - it has good bass but it isn't so low as to cause throbbing bass next door.. Have you thought of W5s? If you like a lot of deep bass you could always have a sub which you could turn on if the neighbours are out! W13 is also a good option as you can turn the gain on the bass down in the evening or if playing at a higher volume or bass-heavy music so as to reduce the issue with neighbours. With regard the amp and a W13 - if you do not have a separate analogue pre-out Sven has connectors for attaching to amps to get the XLR working. With regard to the room nodes: these can be measured precisely with REW software but all I did was play bass tones at various frequencies through my previous speakers and used my ears to tell me which ones were booming, it's pretty obvious when you do this. I did also use the Analyzer app on the iphone and played these fixed frequency bass tones and measured them on the app. It produced the same results as my ears! The W13 come with 4 in-built DSP modes but if you need a specific EQ profile then it would have to be programmed in separately, and I think that has to be done at the factory.
  23. I guess because the Boenicke have a super tweeter of sorts on the rear.
