I am contemplating buying a headphone amp/DAC, but I am wondering do I need one? Is the signal delivered through the headphone plug on my Denon 3312ci receiver good enough i.e. does it have full audiophile qualities just as it is. I have Sennheiser 550 earphones. Will I get a better sound with a separate headphone amp with a DAC convertor? I am also thinking about moving up to the Sennheiser 800 earphones.

Help please!

How do you determine good enough?


If you have the receiver and the headphones can't you decide if it sounds good enough to you?

From my analysis of the service manuals of earlier models (current model not available) it seems probable that this AVR provides headphones with a relatively high source impedance of no less than 33 ohms. This is not a serious problem with high impedance headphones such as the ones you have or are contemplating, but could be more problematical for others that have far lower impedances. I wouldn't recommend this headphone jack for common headphones with 15-16 ohm impedances!


This particular problem is common even with very expensive headphone amplifiers so if you are buying such a thing, investigate this aspect of its performance carefully!

I will assume you are not being sarcastic

, so let me put it another way....is it possible to get an even better sound or what is the path of the signal that comes out of there.

Thank you mate! That helps!
