I sold my Spectral 260 late last year in hopes of purchasing 400's, with the intention of moving into a larger room. Wife nixed the idea, so still in smaller room with no need for 400's (plus the costs of the 400s were, uh, out of my ball park). I delayed the repurchase of another 260 until I couldn't stand it any longer- I was using a well regarded inexpensive amp to get me by. Happy to say finally have another in the house, and wow, forgot how great the amp is! Listening sessions are frequent and long- into the early morning hours!! Gotta love Spectral!
