I purchased a pair of these new way back in the day. I think they are great speakers. Given enough power they can really energize a big room with life like sound!
I found they do like power and used a Classe CA-300. This was a very good match power wise but maybe just a little warm as I found the big Veritas a tad on the warm/dark side with a chance of overpowering some rooms with a too much mid-bass. The combo though was very refined and powerful. I think a Bryston 4B3 would be a great match. I owned a 4B3 well after I sold the Veritas but the Bryston impressed me with its bass control, and the 3 series is smooth and refined relative to its price point, in my estimation.
Enjoy the big Veritas! They will always be a pair I remember owning very fondly.
