I have to say that if you go with JM Labs, the 1027's are the ones to get. They are simply a fantastic speaker. With good placement, and tweaks, the sound that you can pull from these speakers is simply fantastic. I would say that they are at least 90% good as Alto's. I am using mine with a Halo C2 and Bryston amps. I had the 927's and it is simply no contest. The 1027's are much better.
