You know the advantages and disadvantages of this type of amp. Here are some of the specs:

- Drawn Power - 290W
- Output Power - 46W 
- Efficiency - 15% 
 - Ripple Rejection - -29.6dB
 - THD+N - 0.006%@1Khz/46W/4ohm
- Frequency Response - very broad from below 1Hz to well above 50Khz. 

Tips: 

- The ripple rejection is kinda low, so sufficient filtering is a must! 10mF per rail is not unreasonable! 
- This will need a preamp to bring the input level to 1.8V

Efficiency is around 15%. Anyway, keep it up.

Ah, yes. I've neglected the second source.

Right, and "drawn power" is about 300W

Well yeah, the efficiency is twice as low as 30% so the consumption will be twice as high :D
