Looks like an Avalon.
Ah - yes - maybe the Avalon Idea MK2. Interesting - thank you.
(oops - looks like this has been discussed on Audiogon before ; in this article he specifically talks about the "Avalon Eidolon Diamonds")
I was just listening to the set that came out in 2016 - "A Multitude of Angels" - 4 concerts from October 1996 that were the last long-form improvisations he ever did (he already had Chronic Fatigue Syndrome at that time). In that case, he also recorded the concerts himself, using a pair of transformer-less microphones and a Sonosax DAT Recorder.
So - if he is still using the Avalon Eidolon Diamonds then he has had those for a very long time. But - at that price (over 30K I think) - hopefully you wouldn't get the urge to swap them out in a year or two.
That Rick Beato interview is quite good by the way - Jarrett actually plays a few things with just his right hand (after his strokes, he no longer has the use of his left hand).
A garbage system that can sound good enough to verify quality of the recording. That is usually the case. To describe an entire situation a second phrase might help a lot indeed. Not all musicians have budget of Taylor Swift and not all musicians have budget of even an ordinary IT specialist.
I’m impressed. Many musicians have garbage systems. Wonder what he’s driving them with?
HAHAHA! man aint that the truth! thats where i come from. man, it cracks me up...band guys will spend forever dialing in their tone, fiddling with knobs, etc...theyll sweat minor tweaks and changes during playback...then listen to music at home on some BPC they got off the side of the road.
