Amp for JM Lab Mezzo Utoptia's

I've recently moved my (2) Threshold T-200 monoblocks to the HT. Temporarily, I'm using a Bryston 4b to replace the T-200's. Anybody have any suggestions for amps to replace the T200's. I'll be selling the 4b. I'm using a Threshold T-2 preamp and a Meridian 508-24 CD player in a room 25x20 with a 16 foot cathedral ceiling. Speakers are JM Lab Mezzo Utopias. Music is 90% classical and female vocalists and about 10% pop&rock. Thanks.
