I have an ONKYO TX-DS656. Maybe someone else out there has one of these too. Let me know if you have the same problem as I describe below. If you do then I don't feel so alone.
I never can get the volume control just right. By I hand I turn up the volume the smallest amount possible and it is too loud. I turn it down by hand the smallest amount possible and it is too soft. It is even worse using the remote. I see modern receivers and their volume controls let you very finely control the dbs. Like tenth of dbs.
Maybe this is how all these receivers were made (where you can't the volume just right), or made I just got a bad one.
Let me know.
