I've got the XPA2's and the Gen 1 DAC with a Parrasound preamp and another of the 2ch Gen 1's. Ok for the money. The mono blocks can't drive my rebuilt AR9's. Anything below 4 ohms ....trip. Someday I would like to get some Bryston mono's but for now I'll have to try my recapped Hafler XL600's maybe in mono and see how it goes, I just hate the fans though. lol.
