I would have to disagree with Golden ears when he refers to the Accustic Arts Tube Dac suggesting it's fatiguing, must be something else going on.
I have had and compared different dacs in my set-up, most costing substantially more than the AA Tube Dac and in the end preferred the Tube Dac but not with their stock tubes, even AA has come out with their latest Reference Tube Dac and changing the tubes.
You can refer to Teajay's threads regarding this.
I have actually had some of these Audio Aero pieces spoken of here in my system and they are very nice but there was no comparison in my set-up when compared to the Tube Dac and Golden ears you can listen to my system 24/7 with no fatigue what so ever.
I'm curious what was the rest of set-up because something was causing these issues you were hearing.
