Whatever they recently did to the Analog DAC, with the latest firmware (and QUAD USB module - the old module is not very good), it sounds very close to neutral actually. It sounds pretty much like a different DAC to what most people commented on from before 2015.
I have been auditioning the Signature 5 stack for several weeks now, and I am quite convinced the Analog DAC is actually now the lesser "R2R sounding" of the two. How that fares in the grand scheme of things I will articulate when I post my impressions. Also I did not like very much the old Analog DAC, hearing a non-upgraded sample recently. It was a bit too lulling and coloured for my preference towards more accurate sound. Certainly it would have been much closer contest vs the Yggdrasil. And this is yet another way to highlight the relative performance of Yggdrasil, which as I always said punches well above its price.
Some may not agree with me, but actually the Yggdrasil is imo not one of those "dead neutral" sounding DACs. It is a bit coloured, having a hint of added warmness to the bass and mids, and the slight greyness I mentioned. The treble can be a bit inconsistent. Most if not all of this could be difficult to detect outside direct comparisons with other competitive DACs and sources.
