drp nailed it. The nano is just too small to fit even the tiny NX HI-Q BGs.
Here's the thread with the RWA iMod nano:
iMod Nano (56k warning)
The issue I'd imagine coming up with that kind of configuration is that some people would want to swap out the male mini plug for their own Eichmann Bullets, Cardas and what not, so RWA would have had to personalize every iMod nano. Then some people might object to having the pigtail stick out of their pockets, wires breaking in the pigtail from the drilled hole, they want silver instead of copper and vice versa, etc. Personally I don't believe in spending that much money on both wires and connectors as there are countless amounts of other audio offenders in any setup that could only be removed or improved with prohibitively expensive upgrades. That may seem contradictory in a thread about the iMod, where removing cheap components is the goal. But we can't forget that there are limits to how much an upgrade will cost and how much sound improvement, not necessarily sound difference, there really is. This mod was extremely cheap for me in comparison to RWA's offering, making it worth the $20 in caps, Tic-Tac box, cheap mini stereo jack, electric tape and hookup wire, if even $20. I'm all for upgrades that are obviously improvements that aren't restrictively pricey, but after a point you end up paying as much as, say, a much better power supply when you're only exchanging a connector, whose sound upgrade is immediately extinguished by the other crappy components in whatever box comes after it. I'm not saying there's no sound difference or improvement with the
$11/pair Cardas female RCA jacks, I'm just saying there are better investments you could be making.
Nevertheless, maybe someone can come up with an interesting layout for this design. vvs_75 went RWA's completely internal way, but still pulled it off in his own unique way. My way is pretty unique too =D You could pore over it night and day and discover a great method, but I think that time might be better spent elsewhere, like cooking up your own Cardas Myrtle Wood blocks. If someone did do it however, future generations would benefit from it and I guess that would be your payoff, much like I couldn't have done the diyMod without RWA's entrepreneurship.
