Would like to add, I have been living with the sim p-5 and w-5 for some time now and have been very happy. Never a problem, in fact I survived some serious brown outs, foolishly I kept playing the system and no problems. Of course now I'm using battery back-up.
Ayre K1xe vs. Simaudio P7, P8
Has anyone had a chance to compare the Ayre and one of the evolution Sims? I realize that the P7 and P8 are more loaded with gadgetry and cost quite a bit more, but my question regards only sound quality and presentation. Any reliability/ quality control issues? I appreciate any experience you care to relate...
