Leaning towards tubes, but need help long

Seeking an integrated or amp/pre-amp in the $1500-$3500 range new or used. My speakers are the old Conrad-Johnson Synthesis LM260s, which I still prefer over speakers well above their original cost such as the Krell LAT 2. Primarily listen to jazz, especially vocals, orchestral, chamber orchestra, string & brass ensembles. I’m not a hobbyist, so please forgive any misuse of terms. My primary priorities are what I’d call airiness, detail and texture (the separation of instruments, the “woody” texture and action of the fingers on strings, timbre on voices). I also like warmth, musicality or whatever you’d call it, but not at the cost of detail. I’ve never owned tubed gear, but still remember McIntosh electronics from years ago that blew me away on vocals. Was thinking in terms of the Krell KAV400xi to replace the 300i I wish I hadn’t sold, but it was too “in your face” for my taste. Other solid state units I considered were the Naim 5i (warm, but lacked detail) and the T+A PA1230 (warmth + detail, but not worth the $1000 premium over the Krell IMO). Current consideration list includes the Manley Stingray, Rogue, used Bryston power/pre, CJ CAV50 and, if its worth the stretch, a used Mark Levinson 383. Except for Bryston, I’ve not had a chance to audition any of these, so I may be making a leap of faith. Any input, especially in terms of the finickiness of tubed gear much appreciated!
