To be clear... I was not blindly following anything. I thought my buddy’s urging at least deserved an experiment. I came up with something I consider very obscure, even among audio enthusiasts... Also happened to be a question I’ve been chasing answers for from within "our community" and gotten nothing concrete. I'd get a direction to explore, procure a couple tubes, and make an incremental improvement on occasion. I also never got anything like a complete analysis of my amp with my WE300Bs from sources through speakers with very specific tube recommendations. Sounded compelling, but we've all become aware of the BS potential of AI.
Given the relatively cheap experiment to see if Chat’s recommendations were worth considering, I bought the tubes and ran the test. I was skeptical, but for a few hundred bucks I’d rather take the next step and have an answer for my buddy when he asked about my AI experience next time. The amazing part for me is I’m not sure how long it would have taken or even if I would have ever landed on the recommended tubes. I was considering an upgrade to the latest "R" version of my amp, chasing the few remaining veils... a $15K adventure... but think I’m going to be happy for a very long time with this tube mix.
Anyway, enjoy the ride and use AI if it can help you achieve that goal!
