... Whew! any more arguing about balanced and I think I'll loose my balance. Anyway I have tried balanced plugs at a few meets and while I don't deny it sounded clear and great, the only difference I ever noticed was the volume was louder due to this config.
Anyway I have done a lot of research, slept on it before impulse buying (that one helps a lot, trust me!), and heard back from the Audio-Gd man himself. It turns out that while the NFB 11 version 2014 has much improved USB chip and sound over the 2012 version, it's still not comparable to the sound of the NFB 28/29. I'm sure the sound of the 28/29 are phenomenal so I would just about pull the trigger for the 29, but being a bit of a traveler, I have 'nightmares' about lugging that huge, fragile 80's VCR size box around with me. So it looks like my hat goes off the the infamous Gustard which, although DAC only, has the same DAC chip with at least as good (probably a tad better) sound than the DAC of 28/29's, yet half the size and a tad cheaper.
