Thanks for sharing your experience. I only drive a pair of Kef Q150 (86db sensitivity), and originally only had one 48V10A driving both V3 monoblock. I wasn't expecting much when I tried two 48V10A, but was well rewarded. I don't listen to them loud, but can really notice the dynamics change.
I run a separate 48V10A for each of the monoblock, the improvement in transients and speed is hard not to notice. Mine stays very dark, do you run balanced XLR? Can the speakers scale up well with the upgraded electrical?
Sharing what I did to keep mine cool, hoping this could help some people.
Each monoblock is run on a separate 48V10A, and passive cooling alone was not enough to cool it down (I also repasted the internal heatsink).
The solution was: I flipped the bottom up, put external heatsink over, then a...
