  1. Thanks Davide, a very concise answer to my question…..but here’s the gotcha, and I’m honestly not trying to catch you out, just looking for an answer. Lets say that I replace the cheap-as-chips SMTP on the final switch before the server with a DC3, a double regulated and still one of the finest LPSs available. Ive done this and the result is an almighty leap in sound quality. Great. So now let’s say I replace that DC3 LPS with the new kid on the block, the double regulated DC4. I’ve done this too, and the result was another mighty leap in sound quality….so do you think that the same mec
  2. Hi Plissken, I added a lot to my previous post, but the edits were too late and rejected, so in addition to my last post……. Errrr…I’m having some difficulty with the scientific logic here. If there are no variables, there is no comparison. There has to be at least one variable. The whole point is to make a comparison between two things, so what’s the other thing I’m comparing my network with. Surely its an alternate network…..at least that’s how I understand VPN tunnelling? Anyway, let me know the process and I’ll take a look. I really am keen to understand why upgrading netwo

  4. Too many potential unknown variables. With a cable swap the only variable is the current streaming network vs a direct cable. Easy and simple
  5. Interesting! Can you explain the basic physics behind how a better power supply reduces internal network delay and error correction overhead in terms of what’s causing what?
  6. So why does changing from ethernet to fibre optic make a huge difference in terms of SQ? Why can you hear large improvements when replacing cheap network power supplies with much better linear supplies? Why can you literally transform the sound quality by upgrading network components without touching software or end point hardware? and analog noise is an entirely different kettle of fish….nothing to do with what we’re talking about here.
  7. Hi there firedog, I suggest you read the very next paragraph I wrote following those ‘correlates’ “But what we haven’t yet done is qualify exactly what these effects are having on the final music we listen to” Pretty much encapsulates your above comments, I would have thought…..at least that was my intent Also this arbitrary -115dB…..have a look at the amplitude difference between an LHS sourced 85dB @ 1m signal at a 4meter distant listening position at the left vs the right ear. The differences are very small….in the order of 0.4dB on a 73dB signa
  8. Hi Plissken As you say, its extremely easy to test. Just throw an ethernet cable over my bannister rail and connect between router and server, thereby bypassing all my optimisation measures. And the result is a massive downgrade, like I’d downgraded from some Magico M2s to some very much lesser speaker….ridiculously easy to hear the difference. A complete collapse of the fully immersive, 3 dimension musicians playing instruments to a much more 2 dimensional presentation. I actually tried this manoeuvre before spending more money on further improvements just to make sure the effects I w
  9. A better DAC still has the same problem. ~It may sound better but it’s still equally sensitive to the network quality. So your solution doesn’t address the actual problem, given that your better DAC will still exhibit large differences between local and remote file playback as long the remote playback is via a poorly optimized LAN
  10. I follow your logic but here’s the problem. Take any one of the best DACs in the World (you decide which, because it doesn’t really matter), connect it up however you want and have a listen to a remotely streamed file. Mmmmmm wonderful, I’m sure. ~Now go ahead and upgrade the power supply on your pre-server switch from the standard, cheap-as-chips SMPS to say a DC4. And what sounded wonderful previously, now sounds doubly wonderful and that’s because with every piece of hi-fi equipment I’ve ever encountered in over 45 years of very actively pursuing this hobby, they all follow the same r
  11. What I learned by studying the networking standards and theory is that whenever files are moved across a network, as long as the final file is a ‘bit perfect’ copy of the original file, all should be good. But is that true for audio? In audio, we take that bit perfect file and transpose it into an analog voltage stream which we amplify then transpose into sound pressure waves, which we then detect using our ears and transpose twice more, once into nerve impulses then again into conscious music in our brain. And it seems that when the final measure (detection device) is our subconscious limbi
  12. Hi there, i used the word ‘commercial networking products’ when more accurately i should have said ‘consumer networking products’. I’m talking about the stuff that the average consumer is given by their ISP or buys from their local Branch of Curry’s or PC World. Also you are talking high-level Network Standards jargon, while I’m talking about what actually happens physically when a voltage stream from a cable is stored on or read from a local buffer in a network device like a router, switch or network bridge.
  13. And with this set up do you still hear big differences between playback of locally stored and remotely streamed files? I’m talking about the cause of why local file playback sounds better than playing remote files over a typical LAN built with consumer grade electronics. What you are talking about is usually not the cause, rather the fix…ie steps taken to improve how remotely streamed files sound.
  14. Here’s a picture of your average power supply in consumer grade network electronics. The size is roughly 100% ie. correct size. When a data stream is ‘reconstructed’ (I used the word resynthesized) for transmission on a standard consumer network this is typically the power supply on which the data stream is based. Also bear in mind that the incoming power to this supply is 230V AC, so there’s also an AC to DC rectification going on, with all the associated vibration. By removing this supply and powering the circuit from a remote LPS like a DC3, the upgrade is SQ is night and day, like y
