Used to sell it, and have owned it since the mid eighties. Sonic characteristics changed when Keith O Johnson took over design from Demian Martin and so did the complexity of the build and am not as familiar with the latest stuff. Their is a look and sound (a sort of house sonics?) that has been I guess their hallmark. I 'm not going to get into futile discussions of sonics but I love it. It's some of the best equipment out their with when I sold it ,basically 100% reliabilty. Only came back for upgrades. They don't advertize and they don't have to; it sells itself. I'll say this about its sonics, if you want detail, if you want to hear each table of patrons in a night club clapping and chatting at some live performance of jazz and hear that space between and around your speakers, maybe truncated to fit, Spectral can do that in ways I have never heard other equipment do. Not saying other equipment can't, I just have never heard that kind of detail delivered the way that they do. Reviews and opinions are a waste of time; a dead end with equipment like this. You really want to listen to it and hear for your self.
