2100, Am I to understand that you are also using the Almarro with another speaker? Say of a 93dB?
I too found that the Almarro changed in a good way when upgrading the caps. Even the little 205A showed a beneficial change (in my opinion) when changing to Teflon caps. I have been using the V-Caps in these amps for some time. More noticable in the 205A was also going with a slightly higher value. This was more dependant on the speakers being paired with the amp.
The Adagio speakers are, in my opinion, and exceptional performer. I do not have much experience with them being driven by solid state but with tube, you are emotionally connected with the music.
