The Graham Slee PSU1 as offered here is an improvement over the "green" Power Supply.

All Graham Slee phono stages (and also the headphone amps) are supplied ready for use with the 'Green' Power Supply or the PSU1 upgrade Power Supply. Check the product you have or wish to buy to see which one's included.

Here's what TNT Audio reviewer Geoff Husband said about the PSU1:

"My Audion Silver Knight pre has a superb valve phono stage, but only one, I needed two. Enter a 'White Knight' in the form of Graham Slee. He happily supplied two of his GramAmp2 phono stages. These are wonderful devices for beer money and my experience with them made me consider them capable of showing up front-end differences even at the high-end. I was right... Graham even included the optional bigger power supplies [the PSU1], which managed to lift the performance, particularly the sense of scale and openness, to a point where at times they were a match for the Audion stage..."
[Geoff Husband, TNT Audio online audio magazine, Turntable Tests - Methodology]

That's exactly what the PSU1 does - it lifts the performance, the sense of scale and openness.

All the phono stages we offer are capable of matching or beating the high-end, even the little budget Gram Amp 2 Communicator - the old plastic boxed variety being used in Geoff Husband's high-end turntable tests. That is, provided you use the PSU1 power supply.
