@linglingjr, You're missing the point entirely. You seriously cannot believe that your little cellphone or portable DAP has superior DAC characteristics compared to a Sony PHA-1 or Fostex HP-P1? I'm not implying that the aforementioned Sony or Fostex are magical devices but you have to admit that the sound quality is at least at "par" with the source device.
Also, saying that Bluetooth "headphones suck" and implying that all Bluetooth audio sucks is like throwing the baby out with the bathwater. I can tell you that the custom Alpine stereo in my car that receives MP3/MP4 files via Bluetooth from my iPhone does not "suck." The Onkyo receiver in my living room that receives the same files via Bluetooth from my iMac or iPad does not "suck."
Bluetooth itself does not degrade the sound quality. It transmits bit for bit. The DAC is what causes the quality issues. Do date, I am only aware of one Bluetooth headphone that actually does a descent job... The Sennheiser MM-550X, but there may be more. The challenge with headphones is that they need to be the source for the battery, the DAC and the amplifier, not to mention the speaker and sound cabinet. It's tough for a manufacturer to get all of these specifications small enough to meet the needs of the average consumer and still meet the needs of geeky technophile freaks like us who scoff at the mere notion of a slight hump in any part of the frequency spectrum.
My proposal was intended to remove the LOD from the equation. Your headphones still connect to the amp as per usual. The upside is not having to keep the source and the DAC/Amp connected (or even near) each other. It also makes pairing completely universal (assuming they have compatible Bluetooth specs). You don't need to worry about having the right LOD for a Sansa, WM-Port, 30-pin, Lightening, Micro-USB or the like. It also removes the need to double-amp for those who have a Bluetooth device that does not have an available LOD option. You can also own the crappiest device in the world with Bluetooth capability (Archos I'm talking to you) and still end up with amazing sound if the Bluetooth DAC/Amp is top-notch. The source device is nothing more than a glorified Bluetooth hard drive. At Head-Fi we seem to have weird fascination with cables. Cut the cable my friend.
It's cleaner looking, less parts to manage, more universal and just cool in my opinion.
