Amp upgrade from Ayre V-5xe


I am loving the Ayre sound (V-5xe Amp, QX-5 Twenty DAC / streamer). My speakers are the new Revel F228be

While I think V-5xe is great, I am thinking of upgrading to the newer VX-5 Twenty. Just because.... I hear my sirens calling :-)


For you Ayre owners, is this a worthy upgrade?

Or should I consider another solid state Amp? Pass Labs come to mind

Thanks!

The only Pass Labs retailer is Reno HiFi in Reno Nevada. They do however in-home Demos, so I might try that. I would be in the hook for round trip shipping though if I don't like it.
I recently covered shipping to audition the Ypsilon Audio Phaethon. Well worth it.

You think the amp in your system  sounds great, so in a strange twist of logic you seek to divest yourself of that amp.
