Hello,
I have a Tascam US-2x2HR USB audio interface connected to my imac.
With either of my Sony Headphones (detailed below), the sound is fine up to a certain level. But, as the work day progresses, I find myself inching up the volume. Eventually it gets to a place where the sound is distorted. Maybe 3/4 of the way on the dial. Overmodulated? Not sure how to articulate it. But, backing off the volume fixes it.
I’m included the headphone out specs on the Tascam below too.
Anyways, my question is: If I were to try the Beyerdynamic DT770 Pro headphones as a solution, which Ohm model should I try: 32, 80, or 250?
At first I thought 32, thinking that if I used less power from the Tascam it would distort less. But, then I thought maybe I was having the opposite problem. IE. The tascam was too powerful for my current headphones and I needed something like the 80.
Thanks for your time,
Bobby
