Opus 21 cable questions


Ok, I finally have the final piece to my system, as I have purchased a used Resolution Audio Opus 21 cdp. (Well, it is on the way anyway.)

I have two questions:

What balanced interconnect will work best with this cdp?
(I use an Ayre K-1X preamp, which is running fully balanced, fyi.) I don't really have a lot of money, so no Valhalla type suggestions. Keep it under a few hundred dollars for a used 1 meter pair please.

Also, any thoughts on the power cable, and whether it needs to be upgraded to get the best sound out of the Opus 21. Or if you find that your get the really good sound with the stock power cable, let me know that too. Again, inexpensive suggestions are appreciated.

Thanks for all your help, in advance!

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.
I know you want a balanced cable suggestion, but I don't have one as the amps I owned at the time I had my Opus 21 did not have balanced inputs. However, as Lazarus stated, the DNM is the way to go if you want to bypass the internal volume control of the O21. There is a DNM DIN-RCA cable for sale here on AudiogoN (I have no affiliation with the seller) that will allow you to use the DIN output (not volume controlled) and connect the other end to a unbalanced RCA connector on your pre-amp.

Since you mentioned that you use a pre-amp, I'm suggesting the above. I think the DIN output of the O21 is the only output that bypasses the internal volume control built into the O21.

BTW, the internal volume control is very good IMHO, but why have it in the circuit if you don't need it?

Like Lazarus28, I miss my Opus 21 and may end up buying one again in the future. It is a great bargain IMHO....

Enjoy,

Buy the Shunyata Black Mamba power cord, it really refines the sound of the 21.

Happy Listening.
I heard this player at home expo and thought it was nothing special. It was connected using the Din and the top end sounded a bit veiled and unrefined. Be prepared to tune away when you get it home.
