What sort of upgrade from Rega Brio to go with my Dynaudio's X12?

I started to hear the weakness under 60 watts/8ohms with my Dynaudio speakers. There are 100s of choices, depends on your budget. I have been very happy with vintage gear.

CRAP,CRAP,CRAP!DON’T buy into the need more power BS,UNLESS your running in a BIG room OR always listening VERY LOUD!!!
I’ve run Dyn’s for YEARS with lower power tubes & SS amps..Started with Audience 52>Audience 52SE>X14 & now X18’s...BEST ever was pure Class A SS @ 25wpc..Sugden or the new Musical Fidelity Class A will bring out the best of your speakers..

Better sound quality?  Simple send it to be upgraded.  That solves that problem.

Did not mention in my response that I used the Rega Brio (newer, half sized form) for several years and was never enthralled with it.  I chalked it up to the speakers that I was using (Omega single drivers), which tend to do better with tubes.  Swapping in Ascend Acoustics didn't help matters.  I just found the sound to be very flat.  Suggesting it may be the amp, knowing nothing about the Dyns.  

I would try the Elex MK4, for instance, as I like the Brio as a more music than hifi sort of amp.

My budget is 2k max, if you have ideias to suggest.
