Oh, I thought osanto started this thread.... I noticed you didn't start the "Linear Power Supplies - any improvement in sound?" thread in "DIY and tweaks" either....
No, you are correct. I suggested a separate thread (sorry, I should have been more accurate), here:
http://www.runeaudio.com/forum/post12964.html#p12964
(Just to keep the discussion out of the Raspberry Pi3 thread)
I agree that linear supplies are generally an improvement. Not necessarily with the selection of the supply. There are some good ones on ebay, with a description of the regulator and transformer used. Some bad ones too, but quite a few good ones, for reasonable prices.
The place to go to collect information is diyaudio, or a similar web site. Not all people there build up from component level. My opinions are generally ummm... biased(?)... and you can find quite a few discussions and recommendations there.
It is worth it to read up on transformers, and why some are better for audio than others, shielding etc. Lots of information on the internet about that. Same goes for filters and capacitors, even if you never solder one.
