I'm just posting to say that I am (still) amazed by the quality of sound from this DAC.
I have a Level 4 DSD-Only model that's balanced, with Duelund caps & volume control. I run it directly to my power amp and run Windows Server 2012 with Audiophile Optimizer on the front end. I use JRiver to upsample all of my content to DSD128.
The sound is so extraordinary that I'm amazed by it every time I listen.
