Balanced interconnect for Hegel H200

That's a pretty big gamble even if the components were balanced. Sometimes people expect way too much from cables. Factors other than if a component is balanced usually determines how good your imaging and staging is. In your case, ops amp are added to you dac and probably to your amp to make them "truly balanced" connections. Doing it that way may allow you to use a longer run of cables, but with the extra op amps in place, it sometimes degrades sound quality over SE cables. If both your components were "fully balanced", that's another matter. 

If you live in the US, give The Cable Company a call. You already have some good cables, but maybe they have some options for you to try without you having to risk money on something that may not work. Very honest people to deal with.

Have used Cabledyne Reference Copper XLRs and Audioquest Columbia XLRs from Gungnir DAC to Hegel H200.  Prefer the clarity of the Columbias although these took some time for the bass to come in.  Am curious about the AQ Colorados.   

Have also used Cardas Parsec (CDP) and Morrow Audio SP3 & SP4 (phono pre) RCAs with the Hegel.  Investing time to find the IC (out of several owned) that gave the preferred sound from a given source through the Hegel was worthwhile.  Good luck in your hunt.

Hope this is some help, as I too am a Hegel H200 owner and have experimented a few different cables. My present hookup involves XLR cables between my Bryston BDA1 DAC and the balanced inputs of the Hegel amp. The first XLR cables I used were AudioArt, but I recently changed to a pair of Silnote Morpheus Reference II's. The difference was not night-and-day, but it was noticeable and a definite improvement, that is, slightly more controlled and resolved. I'm not too sure about Silnote's marketing though, as they seem to advertise these cables at a very high MSRP but then heavily discount them. I picked up this pair here on Audiogon for (I think) a very reasonable price. Comparing an XLR hookup to RCA, the XLR wins hands down in my system. My connections are different from yours, though. In my case, because my disc spinner, a Cambridge Audio 751BD, doesn't have balanced outputs, I connect it to the DAC with Audioquest Carbon coax through a Wyred4Sound Remedy reclocker.  I think the AudioQuest Carbons are excellent cables for the price. (Just FYI, I have Proac Response D2 speakers and Clarus Aqua speaker cables).

I have both. Not a big difference between the 2.
