Balanced Y Adapters--Where to Find

www.A2Zcables.com has lots of stuff like that.

You may want something better since you're using Levinson, but I've good results from my Cobalt Cable Y's. Very cost effective. I bought a pair of these to use with my Norost SPM interconnects while I saved up for another interconnect pair for the second amp. Now I just use both amp out ports on my preamp which I think is better. I do think I get more background detail now, but I wouldn't say these Y's dimished the sound all that much. I'm sure the Purist would be even better.

To repeat what Nsgarch said - Cardas will make them for you.

I think there were some for sale here last year, but they were very short.

Thanks everybody--I had no notion that there would be this much variety.
