Thanks Soulful, I had a great time with this amp. So much fun, in fact, that I think some of it rubbed off on me as I wrote the review.

I have long liked Plinius & if I upgrade this article will help in what I get next. BTW Much, much grass for the heads-up on Pantha du Prince's Black Noise. I like 'tronica very much but it's hard to find worth stuff sometimes.

Much Grass back atcha, Tony. Pantha Du Prince's "This Bliss" is also very good, but "Black Noise" is my fave - it's a great recording and great music.

Very funny, but for me the difference is that I'm very glad to show and share my gears to my friends.
And I'm not a promiscuos guy, well, just eventually, jajajajaja

...that it kicked out plenty of power into your Revel F-30s.  I'm thinking of mating an SA-103 to a pair of Revel Salon 2s that are equally inefficient, and am hoping to avoid the need for two 103s to fill my 28x16 room.

Entertaining and informative reading.  I am looking for a solid state amp with some "tube magic" in the midrange ... could this be a love match with my Focal speakers?  Nacho
