I understand; whether in my hi fi rig or home theater setup, I never got too caught up in shooting for "reference," being that, as you said, 99-percent of the time you're probably listening way under that. As such, I leave the Onkyo stereo amp's volume readout on "Absolute."
Indeed; on paper, that would be the deal. However, I really enjoy this unit outside of those limitations. The build quality, sound, robustness for the money...can't be beat. I just wish it had provisions for an EQ, but my ears have kind of gotten used to listening to albums with tone controls neutralized (more the way it should be).
I just don't want to jump through the "ghetto rigging" hoops I'd have to in order to make an EQ work with this amp; seems like, after I'd be finished, there would be more noise introduced into the system than is even desired. The weird thing is, I've heard so many contradicting takes on this -- some have told me that an EQ can definitely be installed with this amp, but it would have to run through the amp's TAPE IN/OUT to an EQ's TAPE MONITOR section. Others have said because there's no way to get the signal back INTO the amp, like through a traditional LOOP, it cannot be done. Still others, as seen here, have suggested I can use the ZONE 2 connections but it would be risky in terms of feedback.
I know I can run an EQ through ONE input connected to the amp, like a CD player, but that would equalize just that one source -- I want all the sources, including the onboard tuner, to be affected by the equalized sound.
