I haven't heard the later ARC solid state but their older stuff(D-200 D400) didn't hold a candle to their tube gear of the time in direct comparisons, the Classic series which are my least favorite ARC tube products. Would certainly like to hear for myself but can't imagine any solid state sounding like tubes especially, as Jtinn states, in the area of air, timbre, and midrange presence. But I have heard great things about the 100.2 and reserve judgement until I hear for myself.
Audio Research transistor gear vs. tubes
I would like to hear any and all input/experience that people have or have had with Audio Research transistor components...esp. recent models...100.2, LS-12, LS-9...etc. I have had the chance to own some..and to listen to others.. ...and they seem to be forgotten..or undiscovered....and better than that fate.
