Jeff Rowland to what?


I currently own a Jeff Rowland 625 S2 amplifier. I'm curious as to what amplifiers I should listen to below 20K, new or used. I'm not unhappy, but I'm curious. The amp will be driving Monitor Audio PL500 II's. The preamp is a Jeff Rowland Corus.

I'm a bit late to this game/thread, but thought I'd toss out a name that is seldom mentioned in the amp space: Linn.  I recently went from a Mac MC303 (3 channel 300W/ch) to a set of Linn Klimax Solos (driving B&W 802D2s and an HTM2 center).  Not only do the Solos run amazingly cool (I could cook steak for 6 on the Mac), but my 802Ds suddenly came alive in every respect.  The difference was immediate and astonishing -- clarity, soundstage, depth -- without so much as a burn-in period.  I actually started a thread some time ago wondering why no one ever mentions Linn Solos in a thread like this, and not surprisingly got two responses.  I haven't A/Bed them with other speakers (or against any other amps), so take it for what it's worth.  But I've also never seen a listening review of the Solos that was less than glowing.
Too much disposable income and boredom is a terrible problem to have isn't it? Love reading this stuff! Just had dinner in Carefree AZ at a little Italian restaurant and what do I see? The last amp I bought from him I gave it to the guy that drives by looking for looking for stuff to pick up for scrap. I've had 3. Looking at my system now you coull
