How would you rate these 2 Channel amps

I'm not sure about availability where you are located, but Pass (and Threshold as mentioned before), SIM, and Plinius are top notch solid state gear.

A close cousin of the Sanders amp... I'm currently using an Innersound ESL amp with my Magneplanars. It was the predecessor to the Roger Sanders' current amp, and shares many similarities, including case & construction. Recommended!

Very clean & powerful. I use an Audible Illusions pre with mine.

I would like to chime in and second Cmk's recommendation of the Sanders ESL amplifier. When my CIAudio D*200s broke down 16 days into its 1st anniversary, I was crestfallen but an audio friend (thanks Alex!) highly recommended I hear these amps. My reply, "I've never heard of this brand!" Well, doubting Thomas as I was, I gave the amp a try in my setup (Bent Audio TAP silver TVC, Thiel 2.4s, Altmann Attraction DAC). After about 2 hours of warm up, I could not believe how effortlessly the Sanders handled complex dynamic music. It simply illuminated every musical instrument and singer, separated them and allowed each to shine. The bass was copacious but tight and firm. I did not even feel the need to turn my Subs "on". Transient attacks were hanled with absolute ease. The soundstage widened, deepened and heightened! The HF and midrange sparkled and had a musicality which hinted of the best of SETs. To say I was floored is an understatement! The Sanders never ran out of steam, was cool to the touch (literally). My music system never sounded so good! I can quite unequivocably say that the Sanders ESL amplifier is OUTSTANDING!
