Thanks for your even tempered reply to my hotly worded post. I guess I am angling for some perfect solution that includes Jelly Bean and also sounds as good or better than the DX-100 and also makes phone calls. Can you talk about exact model numbers that might rival the DX-100. Preferably portable but desktop is okay also. It sounds like you are not finding solutions that have the DAC and the amp in one box, that in your view the best sound so far needs 3 boxes: phone + DAC + Amp. IMHO the Amp is the key factor here. Am I understanding you to say that the DACport LX without an outboard amp didn't put it over the top, but that the DACport LX has an adequate DAC, but just needs a solid 3rd box to serve as the amp. IMHO passthru of digital bits and DAC are not the critical factors, again it would be the amp.
USB Audio Recorder Pro is quite interesting because our initial idea that "requires kernel mod" is proved wrong. I was all set to go get a Nexus 7 to use with USB Audio Recorder Pro but then I realized that, well I'd be committed to only that one music player. And it may not handle the music formats I want, or more importantly may not (yet) support DLNA to pull the music off the NAS and the LAN or even the WAN.
We need to either get audiophiles to become Android hackers, or Android hackers to become audiophiles, then we can move the ball forward. Samsung seems to get it, HTC not so much. But even Samsung will likely never back patch their older phones. There, we have to rely on custom ROMs, and cyanogenmod seems like the big dog. That is the only way around the evil dogbert marketing hacks at Samsung... as https://play.google.com/store/apps/details?id=com.extreamsd.usbaudiorecorderpro notes "Unfortunately, Samsung S1, S2 and Note 1 devices are NOT supported because Samsung deliberetely blocks audio devices. S3 and Note 2 works though." Android hackers will "get it" and want to do the right thing. Marketing hacks at Apple and Samsung will want to shine us on and do the minimum, their goal is only to sell new phones period.
This does of course bring up the question of: USB Audio Recorder Pro, on CYANOGENMOD, on Note 1 and 2. I am emailing the USB Audio Recorder Pro guy.
