I have a Sabaj A20h amplifier, but the only power output ratings are for the balanced outputs. The email to Sabaj bounced with an error, so I took what measurements I could. Here's the factory numbers for balanced: 4W(16Ω), 2W(32Ω), 1W(300Ω), 500mW(600Ω) I'm using the SMSL M300 DAC in DAC mode (not preamp, full power).
I set a 200mhz test tone and put the Hifiman Ananda in the same spot to measure with a decibel meter phone app. On XLR it measured 60db and on the single end 54db with everything else being the same. I know 6db either way could double or halve the volume, but most amplifiers I've seen only have 1/4 the power on the single ended side. Is there a formula to solve for SE output power using the known numbers? I have a spare to send in for measurements, but for now just using what I've got. Just got a new DT880 250 ohm in a few minutes ago (I get 4-5 headphones a week) and at -10 volume in medium gain it's about as loud as I'd go, amazing power but trying to pin down the SE number.
