I like your question about the reverse. And one has to be careful with these questions, since there can be a gap between the lower line of a brand and their upper levels of product. So, can be an apples to oranges comparison mistake.
I will add one comment, namely, that I really thought Adcom was very mediocre, but I realized that of my two units -- a tuner/preamp and the amp -- that once I paired a really good tube preamp with the adcom power amp (535L), it sounded pretty darn good. In other words, the amp is still only mid-fi, but it has much greater potential paired with a good preamp than I previously thought.
