I'm sure the Mac gear you mention sounds very nice. In contrast to your SS Classe system it is certain to provide a markedly different sound. I wonder if that difference might be more a matter of tubes vs ss, as opposed to 'old' tube gear sounding best. Have you tried other, more modern tube kits and compared them to the Mac stuff? You might like a whole variety of 'newer' tube gear as well, perhaps even more than the vintage Mac stuff. I guess my question is, on what basis are you concluding the that it's just "old" tube gear...what else have you compared it to?
