Hi,
I also own Spectron Musician III Mk2 Monoblocks with all options and remote sense cables. I have to say they are very impressive. My oldest brother plays guitar and has been in a few bands in the past. He and a couple of his friends heard my stereo and were very impressed. They commented that what they heard sounded so real. I take that as very high praise. I can say that the Spectrons take a long time to break in and it only gets better as time goes on. Please take a listen, you will not be disappointed.
Joe
