Kweifi-about your Sonatas and 2a3 Fi

I've owned my Sonatinas for over a year, LOVE them! I'm considering mating them with a Moth Si 2a3 amp. I understand your using one of Don Garber's Super X (2A3) amps with your Sonatas. I love Don's stuff, but heard that his amps are'nt the most powerful 2a3's out there, otherwise very good. What is your current opinion of your amp/speaker interface? What 2a3 tubes are you running? Sovteks, AVVT's or N.O.S.? I was really concerned about a flea-sized amp driving my speakers but after getting Alan Yun's OK and replies from other happy users I'm sold that it is a "good risk". I listen to pretty low-levels 60-85 db's, simple vocal/instrumental music. 20x14-9 room. Listen in the near-field. But due to extensive ac treatment, my system is quite sensitive to micro-dynamics as the noise-floor is very low. I just do not have to turn it up to "feel" the music. Killer tubes and after-market power cords help alot too. I'm getting the amp, but still interested in your relevant comments. Best regards, MikE
