My comments were about Rotels Pre Processors. Amps are single function, dumb, and binary; that is, for the most part they either work or they don't. On the other hand, pre processors (like the RSP-1572) are a hornets' nest of function and features; and as we all know, the devil is in those details. As for reliability, today's electronics are more reliable than they ever have been; so reliability is probably not an issue. What is an issue these days is support, availability of parts, and longevity of the company. Rotel scores well here.
Bruce, do lots of homework before you buy anything. And if you can, check out used components at Audiogon or other used audiophile equipment sites. In my opinion, component level reliability should not be an issue with today's electronics. I would be more concerned about the condition of the cabinet and display.
