"I apologize for my two digit IQ. Purpose in my lead off post is to solicit comments from much brighter people than me to better understand merits of why tube amplifiers on balance seem to be preferred, after allowing for operating inconveniences."
That sounds so innocent and self-deprecating, but the fact is that you came right out and said that tubes were better than solid state. It wasn't just a question. Even now you say that reference systems using solid state components are likely not suitable for long term use. Your bias is clear but uninformed.
