GRACE DESIGN X MASSDROP M9XX Review

“What won’t is the m9XX’s power. If you can’t get enough power for your headphones from the m9XX you’re either deaf, or you’ve already broken your headphones. It provides overkill voltage for the DT880/600, the T1, and the HD880 at current-stable levels. You’ll bleed long before high-performance mode runs into IMD.”
