"You really think it’s only a couple hours labor per amp? That would mean Krell is charging me over $500 an hour. Krell also told me it’s a huge improvement when these are recapped. "
Don't get sidetracked by listening to people who have no direct experience with how Krell or other reputable manufacturers such as Mark Levinson, Bryston, Audio Research, etc., perform service on older amplifiers. They will do much more than just solder in a bunch of capacitors like a tech down the street. I've had friends who have sent in amplifiers to both Krell and Mark Levinson for service and the amplifiers came back like new. In both cases, they didn't even charge for replacing some of the passive components which were deemed marginal during their final test. They are not cheap but you'll get what you pay for, assuming you plan to keep the units a while. Furthermore, having a certificate from the manufacturer is always a major plus if or when you decide to sell them for any reason.
