Amp upgrade from Ayre V-5xe

I'm using a QX-5 Twenty, KX-5 Twenty, and VX-5 Twenty combination, all balanced of course, based on my long-term love affair with a C-5xeMP.  There is something about the music just flowing with the Ayre gear, but that ended when I inserted a Bryston 10B crossover between the preamp and amp, contravening Charles Hansen's admonition not to do it.  The result was HiFi sound.  Removing the 10B restored the sense of music flowing without electronic intervention.

I don't know, but I'd guess the upgrade from V-5ex to VX-5 Twenty is a worthy upgrade, at least Charles Hansen thought so, and his thoughts seem worthy of attention.

To be clear : I don’t want to change the sound of my system. I want to improve it

  The Revel speakers are certainly well put together, committee design, checks all the boxes, using fine materials with a nice balance and impressive at their price point.
In order to improve on this, it really depends on what you are looking for.
If that, in particular, is hearing more of what the microphone really picked up
with the fundamental, overtones and harmonics all intact
I would suggest you take a listen to a set of Vandersteen Fives or Five As.
These along with the zero feedback Ayre gear you already own IME would
 complete and make a truly special system.

Many good comments already. I’ll add that last year I replaced the well regarded V-5xe with a Pass XA-25. The comparison showed that the V-5xe is decent with the right speaker but not great. IMO moving up the line is a worthy consideration.

Getting a Luxman L509X will improve you sound a lot.

Keeping the K1xe and getting a better amp to go with it will improve your sound LESS. Add to that the search to match both components, and the additionnal signal and power cable needed...

Hope I am clear enough.
