I owned the RL-11 and a pair of A-150's for at least a couple of years without any problems. The 150s just sound better that the 250s. Just my opinion, but I really enjoyed them. I am currently using a Llano A100 and an AES(Cary) AE-3 Pre and while I'm very happy with these I do not regret the time spent with the Acurus.
