1. Things you need to know about the new ‘Conversations’ PM system:

    a) DO NOT REPLY TO THE NOTIFICATION EMAIL! I get them, not the intended recipient. I get a lot of them and I do not want them! It is just a notification, log into the site and reply from there.

    b) To delete old conversations use the ‘Leave conversation’ option. This is just delete by another name.

    Not if “worst offenders” are identified by vague assumption and they are replaced by products which are only vaguely assumed to perform better.
    Especially if not CE certified.

    So much neurosis and self disbelief - what’s so difficult to comprehend? It’s made a very positive difference ..... and what’s a CE certificate outside the U.K.? Is the rest of the world going to burn down... ?

    I am not advocating retail therapy as a solution (or DIY unless you really understand how to do it safely), and I wouldn't suggest changing anything that isn't noisy. There are plenty of SMPS out there that are well designed and not noisy at all, and a whole lot more that are bad.

    There’s an interesting thread on computer audiophile where various eBay Lpsus are measured with predictable results.

    My ears hear much better than my eyes do... ;-)

    My eyes read a temp of 39c and Volts are 12.0 DC

    Really? Probably assembled by a 7 year old girl whose principal tool is a teaspoon.

    You recon, that doesn't sound like a preconceived derogative based superiority complex at all

    Are you using video streaming with the Nas? Do movies look better?

    I'm going to try one. If it shaves :20 from my fap time it's money well spent.

    You had better look it up. Urban Dictionary might help - not safe for work though...

    What I find difficult to believe is on one hand, you are supposed to have an Audionet amp that is totally immune to any switching / digital nasties, yet an improvement has been heard. Without a doubt the new PSU is not improving the signal, but it will be reducing switching noise into the mains. How audible this might be would be extremely system and mains dependent.

    Like i mentioned in my USB cable thread, the SMPS was chirping away.... has been for a few months now...

    What makes you so sure the SMPS nasties where not entering the 5V rail in the USB output on the NAS thus going to the DAC>analog out?

    I see, there's some skill involved then, as MM wants to be speed things up maybe some blue pills may help him.

    Anyhow, the point of this little gamble was to see if an LPSU makes a difference to a server, which it absolutely does. Now it's time to investigate further....

    Yes, a potential issue, which is why I interrupt my +5V rail with a dedicated linear supply, however, I don't think your unit is self-powered, like my USB to SPDIF converter is, so +5V shouldn't even be connected?

    Who knows!! :) I've not got one of those USB cables, my QED USB A to Mini B Performance Cable is USB 2.0 certified.
