I didn't like the bottom end grip of VX5-Twenty on my Sabrinas. My Devialet and the Mcintosh amps I tried did a better job in that regard.
Ayre DACs rule and that's a pretty awesome preamp. I'd maybe look at the MC452 power amp from Mcintosh at the same price.
Note: I'm pretty green, so take my advise with a grain of salt.
