Plinius SA250 Mk.4 vs. Pass Labs X350

If I were you....I'd pick up a second Plinius SA100 Mk III and run them as monoblocks. I'm in the process of deciding between an SA250 or 2 SA100's as monos. I'm leaning toward the monos!!

I like Plinius, but look at it this way. The Pass is unquestionably one of the best amps out there in it's price range and holds it's value as well if not better than most of it's competition. You cannot go wrong with the Pass no matter how you slice it.
Consider this.......
Go immediately to an Electrocompaniet dealer and listen to an AW250R amp. While you're at it, check out the AW180 mono blocks. Since you like the sound of pure class A amplification, I must tell you that I would not be surprised if you posted back later that you took my advice and became the ecstatic owner of one of those amps I suggested. Hell, if you can afford an X350- consider the Nemos. My FAVORITE amp regardless of cost or manufacturer.
Good luck!

I have owned Plinius (SA-100 Mk III) and currently own Pass (Aleph 4). I have heard the X-350, but not the SA-250 Mk IV. I would say that Pass unquestionably makes the better amp on the basis of detail, soundstage, neutrality, high frequency and low frequency extension. This was clearly evident, but the Plinius had such marvelous synergy with the other pieces in my system, it makes this comparison a much tougher one than it should otherwise be. The Plinius has that iron-fisted bass (although it is not that deep) , great dynamics, and a marvelously clean midrange, upper midrange and high end. I don't see how anyone else other than you can weigh the pluses and minuses, ideally comparing these two amps in your system.
