Perhaps it is system or speaker dependent or the sound you are looking for but I like my MK2 with V-Cap upgrade (makes it more liquid sounding). The sound is very musical sort of between tubes and SS but with tremedous headroom and tigh solid bass.
I have B&W 803D speakrs that can dip to 2-3 ohms and the Spectron is stable down to 0.1 ohms which really helps....especially if one has electrostatic speakers.
I tried a lot of amps before settling on the Spectron (I like the MK with V-Cap upgrade more) as it works well with my speakers and system. I use a tube preamp and the combination works well for me.
What I didn't use to like were the round black speaker posts that were not suitable for bi-wiring. However they now use a Cardas regular speaker post and it is a welcome change.
