As i understand it, one reason why the SD is so cheap is the manufacturing method and that fact that the parts are from China. While the XP-7, for example, has a more hand-crafted, manual manufacturing method.
Anyway it will probably cost $150 rather than $99.
The big advantage of his amps is they work great for portable devices for everyday use. Lugging a PPA or XP-7 everywhere can be a bit much.
I don't think I will even take my PPA with me on a plane trip because of security and the hassle. I had a Meta42 amp on a plane with ety headphones and the stewardess thought it was a bomb and I couldn't even hear asking me about it because of the ety's. I think it freaked her out even more because I didn't respond. My girlfriend told her what it was and told me what happened later.
