Upgraded my Hugo2 to a Dave at my office setup and added MrSpeakers Aeon Closed headphones (on the recommendation of Rob Watts) and couldn’t be happier.
For critical Roon listening, current chain is:
Macbook i7 Core > iPod Touch (6th Gen) endpoint > Dave DAC > MrSpeakers AEON Closed
For general listening (like when the iPod is flat, most of the time), it’s an el-cheapo USB-to-Toslink converter feeding the DAC.
No leakage current loops through the DAC, in either setup (for any John Swenson fans out there)
I’m done with upgrades, forever…
