@mahler123 yes, W4S would have been using ESS chips at the time you purchased, it sounds though as you may have bought one of their entry level series and with the various series, they offer numerous upgrades. I'm sure a basic DAC-1v2 would sound nowhere as good as a loaded-up DAC-2v2 or 10th Anniversary Edition at 2.5 times the price of the 1v2. Do you know what model you had?
@jsalerno277 +1 (well said)
@p05129 What DAC did you purchase for $4K then $8K respectively?
@mofojo Yes, I currently am using a Gustard R26 which is an R2R DAC, but as @jsalerno277 suggests, it does sound a little laid back.
