I've had the Arya with several setups, a balanced DAC will help stay in medium gain but short of avoiding high gain mode, you're not in for a noticable difference unless it's a DAC with both filters and colors like the SMSL M300 or DO200. If you fiddle with both you can get it to sound a little nicer. Main thing is having overhead to equalize with a preamp reduction if you want to get better sound. If you're not running out of power or hearing clipping at high volume during busy passages, then keep what you've got and run a few EQ profiles like the one reviewed here for those. APO/Peace has the presets now with the Autoeq button to make it really easy.
