  1. My dual rail DC3, which is connected to my Virgin Superhub modem and TPLink Archer Router responded positively when I placed it on a small Artecama base. It had previously been on the carpeted floor, which can’t be good. From a vibration standpoint, with your SR4s already on a rack, I’ll bet separating them will only make a small difference....of course you don’t know how their fields interreact. I have my 2 DCs on an Artecama minirack....works brilliantly, looks good and is small so easy to fit in next to the main rack
  2. Could someone please provide me with an exact description of what a reclocker does to the data stream. I know all the generic stuff about removing jitter etc but I’m interested in exactly what is happening to the data stream that is processed by the reclocker. I would like to understand a little better why reclocking a data stream ahead of an asynchronous DAC has a positive impact on SQ or why an ultra smooth Linear Power Supply transforms the reclocker. Again I’m not looking for a generic high-level description, I’m looking for the nitty gritty step-wise process of how the incoming data stream is buffered, processed and retransmitted. My deep appreciation to anyone who takes the time to explain the actual nuts and bolts of digital reclocking. Cheers!
  3. All this video does is highlight the shortcomings of the test, which is a MASSIVE confounding variable. Bluetooth? BLUETOOTH???? Have you ever tried to listen to a Naim Mu So via Bluetooth? It sounds like crap....no frequency extremes, dull, lacking detail, lacking any sense of rhythm. All Bluetooth is going to do is reduce the sound of all 3 speakers to a sonic lifeless mush. When I first decided to get into digital streaming seriously I bought a Naim Muso in order to learn about and try all the networking connection protocols. The easiest way to start playing music, which involves no network at all is Bluetooth. It simply lets 2 devices communicate wirelessly. Well I can tell you, the sound was a major disappointment...barely good enough for background music......I say barely because the sound was still irritating when played at even moderate volumes. Its lack of resolution can clearly be heard in the treble which has no sparkle whatsoever and is dull and flat. The bass in almost as bad, without any timbral elements, just the main frequency and the typical one note bass......Dumm, dumm, dumm Link up the Muso with a decent wireless network protocol and the whole thing comes alive and actually starts playing music. It takes the sound from barely tolerable (wincingly bad actually) to quite enjoyable (dancing around the kitchen to Franky goes to Hollywood). So, in summary, all the participants of this blind test did was to listen to the severe limitations of the Bluetooth protocol over 3 different speakers. “And the one that revealed the least amount of damage to the musical signal was ...............”
  4. Sounds like a smart move....keep the engagement and fun bits and hand the sometimes stressful and non-audio related parts over to your successor. Basically switching from ‘more of a job’ to ‘more of a hobby’
  5. I think we all recognise professional jealousy when we see it.
  6. Doesn’t Roon require the Hegel to be on the network in order to find and recognise it. If you’ve only get the USB connection then its not going to find it. Obviously as soon as you use ethernet or wi-fi you have a network connection to the Hegel. Have you tried connecting the Hegel to your network while using the USB interface between Innuos and Hegel?
  7. Would that be ‘Bit Perfect’ with 20ns of random jitter or ‘Bit Perfect’ with 1ps? Both would be Bit Perfect as far as I know, but one would sound a lot different to the other without some reclocking.
  8. There are a few things going on here I believe. Let’s look at the logic. When you isolate your hi-fi system’s data stream from its upstream components, such that no electrical noise is transmitted nor measured, but a change in upstream components has an impact on sound quality, the conclusion is simply that the changes have nothing to do with the noise that was isolated and confirmed absent by measurements. Claiming that no change in upstream components can have an effect due to the isolation is simply denying that other factors may be influencing SQ with absolutely no logical grounds for making that claim. Isolating electrical noise is not going to influence factors like jitter, crosstalk, data errors, data distortions etc etc. Isolation will prevent electrical noise reaching downstream components but will do absolutely nothing for anything that modifies the actual data stream. Further, the components used to execute the isolation could themselves be introducing negative impacts on the SQ that are unrelated to electrical noise. In my experience, the more resolution I squeeze from a system, the more profound the losses due to set-up shortcomings. Conversely, the less resolving a system, the less prone it is to reveal set-up deficiencies or changes. In my system I have complete electrical isolation via a wi-fi link but changing cables, power supplies and routers and modifying the vibration reaching or produced by the upstream components all have a clear influence on SQ which obviously has nothing to do with electrical noise.
  9. By way of feedback I found this whole thread rather uncomfortable. What I really don’t enjoy is a manufacturer or its representatives rubbishing a competitive genre of products with implied criticism based on set-up shortcomings while presenting an ideal case for his own products. I find this ‘tilting of the playing field’ very manipulative, especially when they’re prefaced with ‘holier than thou’ platitudes. As an example, take the claim that any product with wi-fi is a compromise. In fact, the problem, as presented is simply one of limited bandwidth, which is problematic for streaming over any medium, optical included.
  10. I have been an audiophile for well over 40 years and have learned quite a lot about setting up and getting the most out of the equipment I buy and I’ve chased the holy grail of 100% convincing music for that entire time. The Statement, together with some front end optimization has finally taken me to the point where I’d need to get a custom designed room built around some extremely exotic ‘high number’ Magico or similar speakers to make a significant improvement. The Zenith SE will get you 75-80 percent of the way there but that extra 20% is where beauty, purity and ability to utterly convince and enchant lives. How did Innuos design that into the Statement? By minimising both internal and external EMI, creating a built-for-purpose motherboard, designing fully optimised power supplies for each component and re-inventing their topology, by minimising vibration, minimising clock errors and removing critical clock and DC cable connections, and by removing as much noise and jitter as possible from incoming streams. Trying to emulate all these engineering measures by adding a large number of extra boxes, cables and connectors largely goes in the opposite direction, costs the same or more and is IMO unlikely to achieve the same SQ levels When I read your description of your system it really resonated. My system is set up solely for local and remote streaming and is extremely simple...comprising a fully optimised internet data stream based on Sean Jacobs LPSs, the Innuos Statement, Devialet 440 Expert Pro CI amps and speakers. Essentially a rack with 2 shelves. In your position I would either stick with what you have or go for a Statement. I would not try to achieve the Statement’s performance with what are essentially a series of bandaids. In summary I would say, if you have an SE but want Statement performance, buy a Statement.
  11. I really don’t see why that would be the case. Typically reclocking will bring benefits when the total jitter caused by the reclocking device, its interfaces, clock and interface cabling and noise introduced by cabling, clock control circuitry, power supplies etc is less that the jitter in the signal it is reclocking, otherwise reclocking will simply add noise (if the timing variations are random) and/or atonal intermodulation artefacts (if the timing variations are periodic). https://www.soundonsound.com/techniques/does-your-studio-need-digital-master-clock Devices like the SoTM ts-USBUltra with master clock, introduce 2 extra power supplies with their inherent ripple and noise, 2 extra DC cables, an extra clock cable, 2 USB cables plus all the circuitry and interfaces of the devices themselves. Innuos has gone to a LOT of trouble to place the regulators of their power supply right next to the interface and clock, removing any DC cabling from the circuit, they have provided a 3ppb OCXO stabilised oscillator with its own ultra low noise LPS, split their PS to remove vibration and noise, mounted their interface in a low EMI environment and minimised vibration. Its hard to see how the introduction of multiple boxes, boards, cables and power supplies is going to improve anything. It would be like taking a pure mountain spring and passing its water through a treatment works.
  12. Given the degree of refinement engineered into the Statement’s USB its unlikely that a tx-USBUltra is going to further refine the signal. Vibration control, EMI mitigation, OCXO 3ppb clock and direct coupling to custom designed discreet linear power supplies is not going to leave a lot of noise or jitter for a reclocking device to clean up, even when its connected to an external reference clock I tried a tx-USBUltra with sps-500 with my Zenith SE but ended up preferring a direct USB connection via a Synergistic Research Atmosphere X Reference. If I was looking to further gild the Statement Lilly I’d be looking at the upstream rather than downstream side. Downstream I’d just make sure that the Statement’s signal output integrity was protected with really good cables.
  13. Given that we are comparing actual products (Servers) with future Sonore products which are currently unavailable and therefore not tried by anyone, the entire discussion is theoretical and fairly pointless. As I’ve mentioned in previous posts, in digital hardware the actual performance doesn’t always follow what’s predicted in theory so its always important to listen to products before buying. During the building of my current system I tried a number of networking and isolation strategies and the very best I found was wi-fi based on LPS DC supplies throughout, feeding an Innuos Server to my Devialet 440s. Despite the total electrical isolation achieved, several other steps like vibration isolation and selection of both upstream and downstream cables made a difference, so the conclusion I would reach is that complete isolation, while helpful, isn’t the entire solution. I also reclock the data stream before the server, yet ameliorating vibration still improved sound quality. Going back to the OPs question, an Innuos Zenith server fed by an optimised wi-fi stream is in my experience and my installation the best sound quality I could achieve while being extremely straightforward to install and robust in operation
  14. No, I haven’t done that yet. If you look at the interfaces on the Statement, both USB and Ethernet have OCXO 3ppb clocks and dedicated LPS rails so much of the differences reported could be down to cables and interfaces on the DAC side. I’m just waiting for for my last DC3 PS to run in....once it has I’ll give an ethernet cable a try and report back. I have a spare Meicord lying around so while its not quite up to the SR standard, it isn’t chopped liver either.
  15. I agree 100% with Alan’s post. The USB output of the Zenith direct into my DAC provided the absolute best sound I’ve every heard from digital. I also agree that avoiding noise in the first place is superior to trying to remove it later on. Why do I say that? I use a wireless connection between my router and server which should fully isolate the hi-fi, yet everything done at the modem/server level, for example ps improvements clearly reflects in the sound quality. Its as I said in a previous post...theory doesn’t always match practice in digital audio when the criteria is sound quality
