As some like to kid me, I do, in fact, actually open the boxes of the components I buy and actually use them, albeit for as little as an hour sometimes. I've tried many maps on Salk speakers including: PS Audio, Moscode, Rowland, Belles, Sunfire, Pass Labs, TAD, Emotiva, Parasound, Van Alstine, etc. and am extremely happy with the Wyred amps. I am not the expert on amps, but the Wyreds have given me the full frequency spectrum with no emphasis on any one band, troublefree reliability, flexibility to use SE or XLR connections, option to have mono, stereo, or multi-channel configurations, and the knowledge that they really care about and know what the heck they are doing out in California when building these.
I have 2 monos in the 2 channel room and 5 more of their amps in the HT. The flexibility of monos is great but their multichannel versions are not slouches. I went around the horn to realize that "major brand labels" do not have the corner on good amplification.
Disclaimer: I reserve the right to try other brands! But for now I am not considering it.
