If I were you, I would PM John Rutan, his Audiogon Tag is 'Audioconnection'.
I promise you that he will give you the best advice and not try to sell you something.
FWIW,
I think you have some nice equipment. That you feel the need to change is understandable, but, as has been said before
'If it ain't broke, don't bother'
All of us 'audiophiles' want to move onto something 'better', but that depends (esp. those of us who don't have unlimited budgets), on what we can afford.
My 2 cents-
Ask yourself, what do you find deficient in your current system?
I say this as someone who came to high end stereo in the '80's, when there were lots of brick and mortar businesses to audition equipment.
Unfortunately, today, unless you live in a major city, your options to audition are limited. If you are near a dealer, and can schedule an audition, then do so.
What you like is solely up to you.-But, in order to make that decision, you need to know/understand what your ears feel what sounds 'best'.
Please feel free to PM me.
