Just to play devil's advocate, the only problem I have with that research is that they coach people on what constitutes good sound quality. I'm just wondering how different the results would be without instructing people on what to listen for.
I am thinking like you. When I see reviewers replacing 200W ss amps with 36 to 40 W tube amps and talk about how much better the soundstage, etc. is, it pushes my curiosity into high gear. Since I don't have any high end audio shops around here that actually carry tube amps I look for input from my fellow forum members
