Have anyone pics and tech-data for a SU-1 step-up?

I'll add in that a number of years back I had an SU-1 in my system when I had one of the original Transfiguration cartridges with its miniscule output--not even my JP-80's MC stage had enough gain to play it without tube noise problems. The SU-1 actually worked quite well for me, but (1) I had it well away from motors and other transformers, in the same place my Lamm LP2 is now in fact, and (2) I had a VERY difficult time trying to get interconnects to use with it which didn't cause hum problems (the Expressive Technologies interconnects do work with it, but they are roughly as flexible as a garden hose frozen in the winter, and few others I tried (or could afford at the time) save the XLO Signature seemed able to work). Once I got it worked into the MM stage of my JP80 it worked very well (there are those who think that's the best way to use the JP80), although I always felt that the sound was slightly bass-heavy, probably a function of the XLO or the cartridge. Ultimately I sold it when my cartridge was wearing out, as I couldn't afford to upgrade/retip it without selling the ET. Sold mine to a gentleman in the Netherlands for $1700, so I'm a little surprised at the price being asked now on the A-goN--should have kept my unit instead of putting the money in my Keough, I guess. I think that the SU-1 probably is the best step-up transformer you can get, and is beautifully made, but it does come with its own set of compatability issues, and may not necessarily be the best choice in every situation, as Albert notes from his experience.

Give as a later version of the SU-1 ? The first cost 3500USD and the later version over 5000USD - is that right ?

Mine had a list price of $3500 when I bought it in the early 1990s. Got it used then for what I sold it for 3 years later. I did not know of any subsequent price increase; indeed, I doubt if there was any change to it, not much you could change, so don't see why there would be an increase.

Frank,

I have seen and heard an SU1. It sounds just fine and very quiet (no hum pickup). It is very big. I'd say 12" wide by 10" deep by 8" high (30 x 25 x 20). Must be heavy, too. There is a lot of shielding and the transformers themselves are supposedly quite large. It's quite unique.

My guess is that the gain is about 26dB (20:1), having compared it to my new step-up. RCA jacks in and out.

Is that the way on Audiogon ? I , yes I , post a wanted for an SU-1 here on Audiogon ! 3 weeks later i became an good offer and i`m happy ! 2 hours later i don`t understand the world !
