Hey Mike and Joe, not exactly sure how it does this. I do not know if the integral choke filter in the power supply is unique to Viola or is behind many of the desirable qualities I experienced. I have asked Sanjay at Ciamara for some help with your query. I also noticed that with and with ac conditioners or power cords, no real improvement, I just plugged it into my dedicated 20amp furetech receptacle and away we go. I think Ayre has some built in power conditioners I wonder if Viola has something built in that assists in this regard. I forgot to mention I also am excited to mess around with the 2 sets of binding posts to see its affect on biwiring my speakers. Joe seems to have like this even with less expensive speaker cables. I also likedthat Viola doesn't bring out a new version or Mark 2,3 or 4 of a great design. They told me if better parts come out for a particular product they will incorporate it in future builds. They don't try to rewrite the wheel or design if they think it already does a really great job. To me many mark 2 or 3 version r a PR statement to pump up business but not a huge design improvement. I think that's why I also like Hansen's thoughts on his new Ayre dac with dsd. It is essential almost an entirely new design not just a quick addition of dsd capability. He knew after several years there was room for improvement and that is why this new version came out. Nice blog about this on Computeraudiophile where he is a member. I will forward any additional info soon hopefully.
