You might want to consider a used Audio Research pre-amp. They are well built and sound great. That should warm things up.
What pre to use with Vons and Bryston 2B-SST?
I own a pair of Von Schweikert VR2's with a Bryston 2B-sst driving them. I am auditioning a PS Audio PCA-2 for the preamp and am happy with what im hearing but would like a little "warmer" sound. I dont want to spend more than $2000 on the pre new or used. Any suggestions would be appreciated. Thanks
