Since you are only asking about those two amps, I will have to go with the Pass Labs. It is a good amp, but the technology (compared to newer Pass Labs amps) is a little dated. With that in mind I still think it is better than the Proceed. The Proceed is another good product but not in the same league, in my experience.
Which amplifier would you buy?
Does anyone have any thoughts as to which amplifier they would recommend? I am using a Krell HTS preamp with Revel F-30 loudspeakers, and enjoy music sometimes, but am more interested in home theater performance. I have narrowed it down to the Proceed Amp-5 and the Pass labs X-5. Both cost about the same and have about the same power output. Could anyone advise please. Thanks, Jeff
