Wow - such illustrious company on this forum, I feel 'ever so 'umble me lord ... Anyway, my 1 year old SB3 / Classic came with a 5V 2A switched-mode plug-top PSU with interchageable UK / EU connectors, so I guess this is the latest incarnation? Regarding "extra "oomph" ..." I do think the notion of PSU upgrades is fairly well accepted in hi-fi circles; certainly my Naim Audio gear has hefty external PSUs, even as upgrade options on the CD players and pre-amps throughout the range, and noise / stability / regulation seem to be the goals rather than current capacity. I did notice the difference when I added the Naim XPS PSU to my CDX CD player. It wasn't about "oomph" (that was the power amp upgrade) - more about space, clarity, sparkle, timing, the "lifting of the veil" etc. etc. Cyrus kit has a similar philosophy, and the (in?)famous SB+ features a particularly high-quality external PSU as well. PSU upgrades on power amps are, of course, rare since a power amp is essentially a big "modulated" PSU. So I guess the question really is, does moving from the stock switched-mode PSU on a SB Classic / Receiver to a "heftier" (= higher quality?) regulated linear PSU make any discernable difference? And, if so, under what circumstances (e.g digital v analogue outputs, internal / external DAC etc.)? No criticisms of the stock PSU intended of course (although most things DO have budgetary constraints - Marketing 101 I believe). I've been quite happy with the "as supplied" price /performance of all the Slim kit I've got to date, otherwise I doubt I'd be posting this missive. But this is an upgrade thread after all ... If you're still with me - thank you and well done. Graeme -- GRC -Seen it all, done it all, can't remember most of it ...- And if it matters ...
