Ethereal Sound
500+ Head-Fier
So basically, I have an asus xonar essence stx and I wanted to upgrade my amp. Between the Maverick audio A1, Asgard 2 and the O2, which would be my best bet? I currently own a heir audio 4ai and a sennheiser hd 598 and I plan on getting the hd 600/650 or a beyer dt880 600ohm or dt 990 600 ohm. Also, if I get the maverick, would I have to swap out the tubes and if so, how often?
