as a previous (and hope to be soon, again) owner of an opus 21, i have a few suggestions:
1. DNM single solid core cabling with eichmann bullet plugs. inexpensive and amazingly musical. jeff kalt of RA recently designed his newest amp with dennis morecroft of dnm, using his 3d design principles and dnm single solid-core cabling throughout, and the products mate really, really well. i think it's the bargain of the century in cabling and i liked it so much, my whole system is wired with it now. i'm even going to be re-wiring my ATC scm50-A's internally with the stuff.
2. the internal volume control circuit can be bypassed entirely by using the DIN output. i strongly recommend (if using a preamp) that you have a DIN to RCA cable made up, as this improves the sound because you cut out an unnecessary circuit. if you're connecting directly to an amp, then it's obviously necessary though.
3. i don't remember what it's called, but there's also a single solid-core power cable that i used to use with the opus 21 (and that i'm currently using on my dv-50) that is simply wonderful for digital devices and, again, very reasonably priced.
this stuff isn't easy to find, mind you - if you would like, i can put you in contact with the dnm importer.
btw - i was trying to buy that opus 21, but it looks like you beat me to it. :-)
i'm really wanting mine back.
