I am not familiar with Jim's system (not understanding the primary personality), so I will comment on my "immediate" take over that hour or so (not counting the 2-hr. warmup on the side!). The Bolder EE DAC has a much higher output than the regular EE DAC. That I've observed with my experiment here at home, between the Bolder and my unit. Guess it's all due to all those part replacement/upgrade done by Wayne.
With the BC DAC in Jim's system, the sound improved significantly, tho someone commented it was just a slight improvement. Most others thought the difference was significant.
I am still experiment with the BC unit and mine here at home. Will/May update later.
