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

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.

more music than hifi sort of amp

what does it mean?

sorry for not being clear. an amp that, in my view, plays music very well. many other amps are technically more impressive in the way you get details, bass, highs and so on....the rega is very natural and musical sounding in that regard, I think...

oh, OK. yes it's subjective what sound moves you. It's hard to describe what's musical because it depends on the person and the music I like to use the terms "warm, bright, sweet, detailed, layered, rich, airy, direct, spacious, vintage" because I think I know what they mean. I don't understand the meta-language used here a lot.
