I cant wait to hit 400 hours... Very much enjoyable except for some moments after 3-4 hours where i feel it can sound a bit thin and hard sounding... when i reset the computer as i use this for music server via amarra, it can sometimes restore the sound back... could be also computer related ??

also placed Entreq grounding system recently. this could have impact as well.

Yep, I think with good AC voltage stabilisation and proper digital-analog circuit separation, plus excellent grounding you should be (more than) good!

the entreq is a nice improvement to the system for sure !!!
