The signal from the 1212m is coming out balanced (default), so if you use a mono connector, you are sending both channel signals (right and left) to one amp’s channel. You just need to send the right signal to the right channel and the left to the left channel, as an unbalanced connection. Sound is very clean and neat, like this.
Explain how a cable with an RCA on the end is balanced? RCA plugs are unbalanced. Think about an XLR (balanced) plug, you have Positive, negative (180 degrees out of phase), and ground. So three contacts. RCA plugs only have two, positive and negative...you cannot make them balanced.

The signal from the 1212m is going out (balanced), so if you use the mono 1/4 connector, the soundcard is sending two signals thru the cable to the rca connector. We just need one signal to get to the rca cable (unbalanced). This topic has been discussed (here) before. Please, do some search. Thanks.

Exactly, you shouldn’t be sending a balanced signal (using mono connectors) to the rca's (unbalanced). That's exactly the point. I mean, you can but it's not the right way to do it.
If you use the 1/4 stereo connectors, only the right signal will be sent to the right RCA connector and only the left signal will be sent to the left RCA connector. Of course, every channel soldered individually. Thanks.
I had actually forgotten how much I hate soldering cables, but now I remember Here's a pile of (well, five ) XLR-cables for my ongoing, system-wide, unbalanced-to-balanced conversion
The cable is from SommerCable and the plugs are Neutrik silver-plated XLRs.
I'll be making more, but it seems I've had some trouble counting because I'm out of female XLR-plugs
On the Couch: Teac PD-H300 -> NONOZ III DAC -> PPA/Millet Hybrid -> K501/SR325
On the Desk: iBook G4 12" -> META42 w/ AD8620 -> HD330/B&O Form2
On the Move: iPod Nano 8GB -> EX70/ER-6
In progress: M3, Zen, JLH and a new DAC (and more...)
A mini-meet a couple months back revealed issues with one of my DIY cables, issues which became apparent on my system after made myself a DIY power cord. And so I pilfered the connectors off it and built a new cable using the TNT Audio Shoestrings as a starting point.
Started with a 1/4" polyolefin heatshrink tube which I shrunk down then wrapped with Teflon tape. Put Cat6 solidcore cables around it as per the article, then wrapped another layer of Teflon tape on top of that before sticking it through another heatshrink tube, shrunk that down, then threaded it through an old lace from a hockey skate to make it look nice.
Sound? Pretty much as described in the article. Does not bloat up the bass as the old cables did and seems more detailed. On thing's for sure, they look a lot nicer.
I was bored and didn't really like the look of the yellow PET I bought for interconnects. That combined with the fact that I needed a RA plug on the end, I figured I would make a standard [grounded plug-to-IEC plug] cable a little cooler. I removed the outer sheeth, and braided the three leads. I then put on the yellow PET pulled it tight (to show the braid) and used some double wall, adhesive lined shrink tube to hold it down on the IEC side, and just regular 3-to-1 on the connector side.

Those colors are too cool.

It sounds like heaven.
