Spectron III SE vs. Signature III SE MK2

Yes, there is a discernable difference for the better in the SE vs. the MK2 mainly due to the improvements in the reconstruction filter. There are other improvements in the MK2 version detailed on their webpage.

The V-Cap option is also worth it imo but the bybee may or may not be worth it depending on your power source (do you have a dedicated line without a lot of noise on it and do you use a nonrestictive condtioner like the Shunyata with it?).

From my experience the MK2 is a very musical, detailed but not harsh at all amp and one of the best I've listened to.

You have to run it in for 300-400 hours before doing any crtical assessments however.

Yes, I was thinking about doing the V-cap option and not the bybee. From what I have researched on the web the v-cap seems like it has a greater impact.

Radicalsteve,

I wonder if you have tried your unit with single ended input? I tried this on my MkII, and loved the increased dynamics I got. Not going back unless I get another unit and run in balanced monoblock mode. As I understand it, the stereo amp converts balanced input back to SE, anyway. For whatever reason, I liked SE better than balanced.

FWIW, I really, really like my MkII. Best amp I have ever owned, including lots of tube gear. I have owed the same speakers for 18 years, and the Spectron is easily the best match for them.

Do you really like the remote sense cables and have you tried conventional cables?

oofer, you have v-caps or bybee?

I did try the SE but the balanced in was better in my system - more dynamic and lively, probably the cables - 15' run - Transaparent XLR v Harmonic Tech SE
