XLR to RCA conversion


I have learned that my Manley monoblocks perform better using a single-ended input, rather than the balanced cable I am using.

If I were to buy the Cardas converters that would enable me to convert the XLR to an RCA at the amp end, would I (1) have to do the same at the Audio Aero Capitole output end or could I just convert the input or amp end of the connection?

I have to use my 40 foot balanced interconnects and want to go single-ended at the amps and HOPEFULLY still get the benefit of a balanced cable and the noise rejection it provides.

Thanks in advance for your help.

I'm running a single ended Cardas Golden Reference IC from my CD (MF Nu-Vista) to my pre-amp (BAT VK-3i). The MF has only single ended connections and the BAT has both SE and balanced. When I tried SE to SE, the sound was OK, but then I tried SE (output) to balanced (input) with the BAT adapters and ... WHOA! I picked up much more gain and the sound was fabulous.

It appears that going balanced TO the input provides more gain than going balanced FROM the output. Don't know why this is. Anyone have an answer to this one?

As to your idea of getting only one end of the IC terminated with an XLR, I'd forget about it. The re-sale value is likely to be nil and you may eventually be stuck with a cable you won't want anymore.

Well I have a balanced Placette linestage which I can choose to have single ended inputs installed. So I'm deciding whether to get that modification or simply get a RCA to XLR cable.
I added a pair of Cardas single-ended adapters to the amp end of the interconnects and all I get is a buzzing sound thru my speakers. I turned everything else off in the room and still get the same buzzzzzzzzzz.

Maybe it's because I didn't put the same adapters on the source end of my interconnects?

Any input will be appreciated. thanks
I've eliminated the ground loop hum and the change to single-ended at the amp end is remarkable. Much better soundstage and slamm. In addition, I was surprised to see that I got greater GAIN by using the single-ended amp connections at the amp end. This is exactly the opposite of what I expected since XLR's normally provide a 6dB gain. I plan to call Manley and discuss, but if you're a Manley owner, you must use single-ended at the amp end to get the full potential of these fine amps.
