Hi everybody, I was hunting for second hand amp in local stores to replace my cambridge 640a, and found Audio Analogue Puccini Remote, Consonance a100 linear, Consonance a100 hybrid, and Pathos Classic One (mark one) they are all priced nearly the same. Which will be the best match to my system. It is Vienna Accoustic Haydn(not grand), QED silver Anniversary XT, shek d1 DAC + squeezebox. and audioquest panther interconnect. My main interest in sound characters are sweet, rich and warm. I would like any advice on this.. thanks a lot in advance, wun
