How are you driving those Grados with that AP2496?


With a Creek OBH-21

IME the AP2496 is not really designed to drive low impedance headphones like
Grados. It can work, but there might be some audible frequency response
variations due to the impedance curve of the headphones interacting with
relatively high output impedance of the AP2496. I'm not saying that the
output impedance of the AP2496 is high for a quality audio interface, I'm
saying its high for a headphone amplifier.



Oh OK. Darn it. I only just bought this combo and can't really afford to
get something else. Thanks for the info anyway.
