XLR cable with RCA output

I use RCA out from my Audio Research PH7 Phono (RCA)to ARC LS26 line stage XLR inputs w/Cardas adaptors with great results. Sound opened up, much better, more transparent a great improvment, then used LS26 XLR out (also w/Cardas adaptors) to the ARC amps.

The only unit I have that has XLR in & out is the LS26, I don`t know a great deal about "electronics" but I think what happened is that the XLR "path" within the LS26 reveals more detail and is quieter. "a no going back" upgrade.

Cheap adaptors will kill you. You have to spend decent money on the Cardas. Otherwise you will get humm due to the impedance imbalances and other issues.

I used a pair of RCA to XLR cables between my Cary preamp & Atma-sphere amps with pretty good results. They cost less than $20 at Sam Ash. I also tried XLR adapters (not Cardas) but there was a significant loss of sound quality. You could try these before spending more money.

I also have a pair of RCA to XLR cables for my surround channels. It's usually better to limit the amount of connections to as few as possible. It's worth noting that unless you're only connection option is XLR on the amp you may as well just do RCA to RCA, but try it and see.

Purist Audio also makes the adapters and if you can locate them Infinity Audio makes a nice set too.

In my case I just had my cable reterminated. In hindsight that probably wasn't too wise as there is not much of a market when selling these cables.
