Balanced vs. Single Ended Interconnects

Though I may be mistaken, it looks to me that your Pathos Classic One Mkiii is not truly balanced. That is, it does not use differential circuitry; the balanced inputs are either transformer-coupled, or simply single-ended inputs on XLR connectors. If that's the case, you're not likely to get much (if any) benefit from using a balanced cable.

According to Ralph (Atmasphere), if both components use true balanced architecture, there is minimal benefit in using uber expensive balanced interconnects.  Ralph, if I have misinterpreted the above feel free to correct me.

IMHO there is really never any situation where using really cheapo wire is advisable when Blue Jeans, Redco and plenty of other companies sell interconnects (and speaker and other wire) using excellent Mogami and Canare wire at VERY reasonable prices.

@cleeds about 6.50 in Kevin addresses the balanced input question. It is fully balanced according to Pathos.

I'm not sure whether the Pathos Classic One is fully balanced or not. In the video, Kevin says it has a "fully balanced front end." That sounds to me like the amplifier itself is not a differential design, @jerryg123.

But, with that front end, I can see that there could be advantages to using a balanced cable.

For whatever it's worth I have done a lot of critical listening over the years with a lot of different high-end audio equipment and at short distances (1/M - 1.5/M) and I have not noticed a difference in the music comparing XLR to RCA other than I acknowledge that when the volume is set at the same level the XLR cables are about 3dB louder. Therefore assuming your equipment has both RCA and XLR inputs and outputs I recommend staying with a good pair of RCA interconnects unless you are talking about extremely long runs.
