Hi TG

Looks like no one has. I just ordered my Genera kit last I decided, that despite my love of MC I really did need a decent MM phono in the house - sometimes I want to play something that really rocks

But I have the PSU1 with the Reflex C, so I will eventually get to try the combo.

cheers

I haven't but am very tempted because I could run my Genera and Novo from one PSU1... and when I eventually buy a Solo UL I would buy it with the green psu.
 
But in the nearer future your observations on Genera with PSU1 would be very helpful gmdb. And the Genera is very good on every level, including the kit which I have eulogised about elsewhere.
 
Best wishes

Well I inadvertently tried the PSU1 with the Genera. I told my wife that the Genera could run off the better Graham Slee PSU and she switched them over without telling me. So there I am going Wow, this Genera is just getting so good, its getting closer and closer to the sound of the MC system.

It helps to understand I think that I started out listening to the Genera on an old Dual 1219. Great turntable, just a pity about the tonearms on them. I now have it on my second Rega, playing a couple of $200 carts. The arm on the second Rega is a standard RB250 and I am really starting to appreciate what good arms they are, even when unmodded.

With the PSU1 in place, on some records the second Rega delivers a more enjoyable listening experience than my first system which has the Reflex C as its phono stage and a Michell Tecnoarm (essentially it's a modded P3-24). Why I have been asking myself? And I think the answer has to do with the fact that my MC system retrieves so much detail that on some records the music gets in the way of the song. Does this make any sense?

So matching the Genera with the PSU1 gets you close to the openness that you get from MC, improves clarity at the mid-range and high end and improves the already decent MM bass, making it just a bit more round and tight. I know some people love what I call "fat" bass but I'm not one of them. I play quite a bit of reggae and "fat" bass turns reggae to mush.

Thanks Geoff, I just ordered a PSU1 and I am now very glad I did it. I'll share my comments after it arrives. Your description of the clear midrange and tight bass has increased my anticipation.

Update:
It is indeed a step up from the Green PSU that comes with the Genera. The PSU1 does cost more than the Genera itself but it further refines the preamp's transparent and rhythmic sound.

Good info Geoff & Jon

Sounds like the sort of thing I might have expected from recent tinkering of my own with a few other things.

Big, clean, power supplies seem to have a lot to contribute in many areas of audio reproduction.

I originally came to the a better understanding of power supplies in a roundabout way. Before I was in the doubters camp. I was getting too many bizarre hums in my system that were none of the obvious things. So, on advice, I tried a decent mains filter system and that resolved the problems as well as improving the overall sound reproduction. But sound is such an objective things that I found the the easiest way of demonstrating what impact a mains filter had was by plugging my old Sony CRT TV into it. The improvement in the quality of the picture was dramatic.

With a dedicated PSU designed for a particular piece of equipment then the result should only be better.

I do wonder however if there are places where it wouldn't be necessary e.g. places that do in fact have a consistent power supply. This is not the case in Brisbane: here we have frequent brown-outs (quite spooky those ones; black outs; lighting strikes and a power-supply that can fluctuate between 220 and 280v. In these conditions it seems obvious that a PSU that delivers clean constant power is going to be an improvement. The logic defies any doubts I previously had.

One thing I remain unsure about is whether it is best to run the PSU1 on the mains filter board or direct from the house mains plug. Heed with their offboard turntable PSU advise not to run it off a mains filter. I think the reason is that having two boxes "tinkering" with the power supply is likely to lead to them interfering with each other, rather than working together.
