I think they are. I have read that the headphone outputs on high end equipment often are not up to par with the same quality of output as the device. I built a cheap cmoy headphone amp using a Burr Brown 2227 opamp. I use it with
Grado SR-80 phones and WOW. I didn't believe the sound. I can't believe that high end phone amps do much better. I took my homebrew amp into a high end audio shop and they said it sounded like a 250.00 phone amp. You might consider building a cmoy amp. Many places on the internet with info. Dean
