I have no idea if the La Voce had been upgraded when I heard it, that has been a few years back. We did a blind test on 20 DACs then but this time it will be maybe 15 and we will be using at least two versions of the latest Yggdrasil. Last time we had an early version of the Gungnir as well but I own one so it is easy enough to compare one with one of the top few DACS I bring home for an extended listen. I suspect we will have at least 60 total test subjects including myself, last time we had that many or more and my results were pretty close to that of the group. I had two DACs reversed in the final order of finish. I will say that Schiit is the only company from which we are allowing multiple DACS.
We are using an $8,000 maximum cost so that eliminates other Aqua DACs.
This comparison is not for everyone and I will use our tube comparisons as an example of what we do. Say a person likes a slamming bass, or increased mids or whatever, those are just a few criteria, we rate on 25 so a tube may have a few characteristics a person likes but may test lower on several others. Some of the top 6sn7s tested well across all criteria and those numbers were an average of what the entire group thought. It is a 100 point scale so some tubes ended up in the high 90's, others in the 60's or 70's yet even the ones with the low scores might have been wonderful in a few areas.
Some 6sn7 tubes sold for $1,000 or more, a couple were priceless because they were one of a kind. (engineering samples). No tester knew if a tube was a well known brand, was worth $1,000 or $25. That eliminates bias. To this day people swear by specific tubes but I can tell you many did not fare as well as those people might hope. This is not my system, it was a group effort and many of those involved are pretty well respected in their fields. My role is relatively small, I built all cables being used and I designed and built four tube amplifiers that we use on occasion. Some things I would have to talk about in PM but I will just say it is an easy way for me to hear and evaluate several DAC's at the same time with the same music and the same gear. I cannot do this going from one Audio showroom to another.
I will not know which DAC is which, if we are going by weight the PrimaLuna weighs 28.7 lbs.
