This is food for thought. In this month's issue (192) of Absolute Sound magazine in the review of a Pass amp and preamp, Anthony Cordesman said "I have never been a believer in choosing one type of amplifier- tube or solid state, or Class A verus class AB. The best and most neutral amplifiers still don't sound the same, but the way in which an individual design is executed now tends to be as important as category. I could live very easily with the best examples in each category. I also find that the sonic differences between tube or solid state, and class A and class AB are becoming smaller over time."
It will be a sad day for Audiogon when all amplifiers of all types and categories sound the same. This section of the forum might as well be shut down. Wishful thinking.
