Denf, would you be kind enough to post your impressions of the Musician II compared to the JC 1's. And did the Spectron have 400 hours on it. I know from personal experience my digital amp took at least that long to really open up.
One of the attractive aspects of digtial amps for me is the lack of heat. Should I need more power with a speaker change, the Spectron would be a consideration.
I am sure the JC-1's are great, but not in Hawaii !
