Spectron III SE vs. Signature III SE MK2


Any impressions from those who have owned the former and now own the latter. Discernible sound improvement with MK2?

Also, anyone install the V-caps. How did that work out.

Feedback would be greatly appreciated. Thanks

I have had my new Spectron III SE MK2 for 2 weeks so it is still being broken in. After a rough 100-200 hours of break-in and 24/7 music playing the sound coming out of the amp now (around 300 hours) is, as the kids say, awesome, absolutely awesome. I can really crank her up now. The difference between the MK1 and MK2 is easily discernible. I had both upgrades put in but not being able to compare to a stock MKII I cannot tell you how much they contribute to the sound improvements. I can tell you though that the clarity of sound is spectacular and I would have to assume that the Bybee upgrade is contributing to that. That's all for now.
Regarding break in for the MK2 upgrade: What do you suppose is the 'window' of time needed when looking at two scenarios: just having the amp on 24/7 with 1-2 hrs of play time per day vs. having a source playing through it 24/7? I need to balance my desire to hear the upgrade in the near future and to not drive my spouse crazy.
Got my 2nd Mk 2 on order, for monoblock-isizing!!! Can't wait. I'm an idiot for wanting to fix what ain't broken 9my system sounds glorious right now), but by all reports the monoblocks "go one louder". I'll report back, once they are broken in. 2nd amp arrives in a couple weeks.
