I'm reaching some important conclusions. I'm so satisfied with my Abyss 1266, that I'm going to discontinue my interest in pursuing the Susvara. It's so much money for another TOTL "flavor", so I'll just concentrate on my Abyss 1266 and maximizing what they have to offer. I believe my Woo WA22 drives them pretty well, although it's only 1.5 watts and a tad more if I use 5998 power tubes.
I'm still continuing my research on solid state amps (having heard my Abyss 1266 with a local owner's Wells Audio Milo). I probably won't get the Milo, as I've heard some not so great feedback on the quality control and company owner. I've narrowed it down to: Ferrum Oor/Hypsos stack, Burson 3XGT, or Headamp GS-X Mini. I know there are some amps above this price point, but not sure I can afford them.
