Pass XA30.5 vs. ARC Ref 75


Has anyone compared these two particular amps? I own the Pass, and I'm thinking of test driving the ARC (a.k.a. buying it on Audiogon, and selling if I don't prefer it to the Pass).

Amplifier magnifies electrical signal to drive speakers. If one goes by straight scientific terms, it just increases the voltage and current of the signal, adding nothing and losing nothing. In fact it is not difficult to have am amplifier to do just that. But the sound would tend to be plain and harsh.

Music makes up of harmonics. Without it, music is just any sound, no soul and feelings. Some amps are better in keeping and enhancing the harmonics. They sound better, more involving and satisfying. It is the strong area of a tube amp and this is Pass Labs just cannot give.
