Does Audio-GD even still make the NFB-15? I know the webpage for it is still up, but the product isn't listed on the products page. I have one, and while it does sound wonderful, when you have problems and have to send it back to china...lets just say you're looking at half the cost of it to use anything but USPS(assuming you live in the US of course). I got lucky that mine made it back after failing to be delivered, I made the mistake of using USPS, and learned from that. Luckily USB was the problem and optical worked out fine, sadly after years of owning it I've recently had sporadic static lately that I'm unsure of the cause with no good ways to test, especially with how random it is.
Guys, added the Fostex HP-A4BL DAC Amp w/ Balanced output to this list. This fantastic headphone amp at $399 MSRP is great for anyone who needs a balanced output or wants to upgrade-proof themselves. It's made available by a well respected Japanese company, so quality should be top notch. It'll be hard to find anything that's better value than this anytime soon.

Here is some discussion about it on Head-Fi: http://www.head-fi.org/t/792916/fostex-hp-a4bl-the-a4-with-balanced-output
Hoping for your votes on this to get a drop!
Schiit doesn't do deals, so why they're always suggested baffles me. And unless you can acquire a huge stake in the company or commit to buying a huge run, it's not going to happen. I, for one, would love to see the HA-1 get dropped.
