While I could reach levels that satiated my desired listening level, I came close to max (26 out of 30 on the volume) to attain that, even on full volume LO. At full volume, I could listen, but it was beyond my comfort level. Some may be able to reach that full-volume level, but I could not.

All of the other listening headphones were able to be powered through the 4.4mm balanced jack with ease.

I never had to move past 22/30 to attain an adequate listening volume. Combined with a source input that has plenty of juice, though, the CH-Amp Signature could readily drive anything I sent its way.
