Asking suggestion for $15,000 audio system for classical music

I'm a classical-oriented guy who plays, among other instruments, violin & acoustic piano.  I go to my share of classical concerts.  Tone quality and imaging are what I crave.  Slam isn't my top priority and I really don't care that my system wusses out beneath about 30hz.  I only hit 90 decibels on the stereo once every blue moon. What drives me nuts and what I try to minimize are edgy vocals, strident strings and boomy bass.

Anyway, I'm truly loving my current system...all btw carefully positioned in a fairly modest-sized room.  The components are...mentioned in reverse order to properly denigrate my addiction to audiophilia...  Nola Boxer speakers.  PrimaLuna Prologue One 30 watt tube integrated amp.  A Mytek Brooklyn Bridge that is usually streaming Qobuz & Primephonic.  An older Sony CD/SACD player (I use the Mytek to stream the CDs).  An older SOTA turntable with Alphason arm and Lyra Delos cartridge piped through an elderly but still game Moon LP3 phono stage.  A variety of interconnects from companies that include Cardas and Straighwire. Acoustic Zen Satori speaker cables.  An old Paradigm subwoofer.

My equipment is not that impressive. I bought them many years ago. Table is Denon DP300F, cartridge is shure, speaker is B&W 600, amplifier is Marantz (old model), CD player is Marantz

audiotroy, onhwy61, and the rest who suggest going to the dealer make the best point. Go, listen, take it home. Ignore any specific name/brand recommendations here

"TC is $300 for 1.5ml."

Uranium is $45 per pound. Actually, even less in the beginning of this year.

Hello! If you want to get the best out of your 20,000 I suggest you consider used equipment. That's why there's Audiogon and A____ Mart. That's how I built mine. 

I am being redundant, as the OP has stated that he has a lot of vinyl and no SACD or BluRay.  However, he is looking for a disc spinner, and given the sheer amount of Classical available in SACD and BluRay I would strongly (re)advise getting a Universal Player.  I can’t emphasize enough how good some of these discs sound, particularly in Multichannel.  He may, just for giggles like to experiment with vinyl vs CD vs SACD/Blu Ray of favorite recordings.  For example, I just obtained the DG Karajan/Berlin cycle on BluRay.  Even in 2 channel the sonic benefits are obvious—much more hall acoustic and reverberation.  Last night I was playing a Pentatone reissue of a 1970s Quad recording from DG (Christopher Eschenbach in Beethoven PCs 3/5 with Ozawa and Hans Werner Henze leading the Boston SO, and even on a midfi HT system the soundstage and detail are utterly believable (the SACD cost $3.99 from BRO).
  Universal Players run from $400 (Sony) to a grand (Pioneer and Yamaha), or he can spend in the stratosphere if he wishes with the usual suspects (Esoteric, etc).  If he prefers to use them as a transport into an external DAC they have digital outs.
