Noting the various comments posted here, I ordered a PSU-1 for my Revelation M, having bought it with only the basic power unit. It arrived at the end of last week (thanks John!).

Before playing any music I thought I'd compare the volume at which background fizz becomes audible through the speakers, so in scientific manner pressed an ear the grille. It seemed to occur at a point when the volume control is set -4dB higher than when the Revelation M is powered by the basic power unit. A good sign, thought I.

Returning my Pre-amp's volume to -60dB, my starting point for records, I cued Berlin's Love Life. Having played it a couple of days before after a break, I'd thought it a little dull around the edges. I'd barely reached the sofa before being pinned to the back of it...the lower noise floor had been translated into volume - not sure how that works!

However, having settled to a comfortable listening volume, two sides of Berlin (not dull about the edges at all) followed by some Blancmange and Yumi Matsutoya, it was very apparent that there was more to this than volume. I don't want to sound as though I've been reading too much magazine review jargon, but there was a fuller sound from top to bottom, with increased instrumental separation which was quite audible. This wasn't upgrade expectation, as my wife commented to me about it sounding 'different' from two floors upstairs. I've had one more listening session this week, but unfortunately other things have got in the way, as they do.

What had I expected? Well, I suppose a more subtle version of what I heard. The PSU-1 costs about the same as a replacement stylus for my Goldring 1012GX, so as an upgrade I'm very pleased that I bought it (better late than never). Big smile

A good summary of the benefits of the PSU-1 Graham!

I had a similar experience with a Solo headphone amp a while ago now. Going back to the "green" PS, the dynamics decreased and the soundstage narrowed. (I'd had the PSU-1 come with a loaner phono amp and thought i'd try it on the Solo. Needless to say all my kit now has PSU-1s!).
