Hey Charles,
Not only is fair to claim both of us are Jazz lovers I have Lee Morgan and Lester Young tattoos on my arms to prove it!
All the gear that you mention is still in-house in my smaller up-stairs system. It's a great solid state system, however as we both know it does not sound like a great tube based system. As one of my listening guests said ,"your up stair's system sounds like great HiFi, your down stairs system sounds like great music".
I want to share I'm not a great fan of KT-88-120-150 based amplifiers because they sound "solid state-ish" to me. I also find any gear ( Audio Research, BAT) that uses the Russian 30 super tube in its design quite unpleasant to my ears.
Now, El-34's, 300B's, 211's, 2A3's, 845 based amps SET or Push Pull that sounds like music to me, with the right line-stage, like the LTA's Micro-ZOTL which is still the best preamp I have ever heard in how uniquely deals with space and macro-dynamics, now we have music to my ears/personal taste. I have never been a fan of horn designs and have reviewed single driver designs, which have a beautiful purity but lack extended highs/lows that can be easily driven with a few watts. Now, that I'm using the DI's I can play with all these great tube low watt amplifiers, without any drawbacks at all.
