I have a buddy who has just been bitten by the HT bug. He's thinking about a second-hand Classe SSP-25 and CAV 75, and he wants me (the supposed expert -- yeah, right) to vet the choice for him. Since I'm not familiar with Classe gear, first-hand, I've spent the first half of the weekend surveying the review literature, and the sound of the stuff would seem to be first-rate, but there do seem to be some unnerving themes regarding performance and reliability issues.

Does anyone have a SSP-25 (or an SSP-75, since that's undoubtedly what my friend will talk himself into sooner or later), and/or a CAV 75 or CAV 150, and care to comment on the performance / reliability rating for these products?
