Alternatives to Pass Labs
Pass Labs are great amps but are expensive too. Are there any other good amps (stereo and or multi-channel) that are as great sounding as the pass labs products but not as expensive? I had an (borrowed from a friend) an Aleph 3 and I felt that the Aleph was on SS(solid state) amp closest to the tube sound but at the same time retaining the SS features.
