Hi Sjhall, I owned the Spectron MIII for a few weeks, and now have the JC-1s.
In my system the MIII was impressive sounding initially, especially the powerful, taught bass. However, over time it was clear that the mids and highs never sounded relaxed at spls above 80 db in my system. Soundstage bloom is only fair, and the MIII favors speed over letting notes decay naturally. Its basically a good amp, but a bit pricey now at 4k imo.
I agree totally with Denf's assessment of the JC-1s in comparison. Its a different animal, and worth the price difference if you have the room and can deal with the additional heat the JC-1s produce.
