I am in the other camp in the NNJ/NYC area. Many audio clubs, dealers. manufacturers, reviewers, etc. Plus I get to repair and modify components daily so I get to hear so many components and get to experiment weekly. Yesterday I fished building three power amps, all built by my partner. We compared three hybrid amps. two with 6SN7s (one has a single tube per channel the other 2 6SN7 tubes per channel) and one using 6DJ8 tubes (1 per channel). Interesting outcomes.
Back to your question, No matter how many audio friends you have or systems you can listen to, your ears are all that matters. There is always something better in one aspect or the other so there is nothing perfect and it all comes down to compromises and what you prefer your system to sound like. I play guitar and to me no system does the guitar right. Nice reproductions but nothing real to my ears.
The amp you have should sound very nice, it there better, yes but what do you feel is missing? Sometimes you find something better in some areas but not all. Even when I repair or build something, there are several ways to go and each time I give up something for something else.
Happy Listening.
