Looks like a potential competitor to the basic T-Amp.

Quote:

"Unfortunately, we discovered one major drawback. While the audio quality was excellent, we noticed that our wireless keyboard and mouse stopped working whenever the amp was on. Some experimentation revealed that the effective range between the peripherals and the wireless receivers dropped to about a foot or less from six feet or more. A second, more robust wireless keyboard and mouse dropped to about three feet from twenty. The range dropped even further when the volume was cranked up high. Clearly, the Kama Bay Amp has EMI shielding issues, and not small ones either. According to Yamaha's spec sheet, the switching frequency of the amp is in the realm of ~500 kHz, and this is where you would expect the worst interference to occur. This is two orders of magnitude lower than the 27 MHz band used by wireless peripherals, so obviously the interference is not restricted to the 500 kHz band."

That's a pretty severe problem given that they expect some users to place it inside of a computer.

Wow, this amp destroys wireless devices? Haha, that's crazy.
 
I think Yamaha fixed something in the SDA 1100 upgrade over the SDA 1000.
 
I'm selling one now.
