Warm, Deep Stage, S.S Dual Mono Amps ?


Looking to step up from my B&K M-200 mono's, anyone familiar say, with semi-older Rowlands, Classe, or similar classics ? Speakers are Dahlquist DQ-30I's with 91db,& 4-ohm nominal. I want to stay with dual-mono, (2 chassis), system & cables are configured for it.

Calling Tunes4me & David99, tell me more, I've been awakened, give me some comparatives maybe, sonic characteristics please, such as presentation, depth, warmth, openess, dynamics, etc.
Lets put it this way, for 500, you get an amp that has been compared to Spectral (3300.00) and several more, check out the review @ www.6moons.com.
