Specs
SPECS THAT MATTER
Power: Plenty for all headphones except a handful of the hardest-to-drive ones (we’re talking HE6, Tungsten, stuff like that)Noise: Inaudible on all headphones and IEMs
Distortion: Unmeasurable at normal listening levels; 1000x lower than the typical headphones you're using
Heat: Amp gets slightly warm without DAC card, moderately warm with DAC card; this is fine, we have made much hotter-running stuff that lasts farrrrrr past the warranty
Size: Extremely desk-friendly
