Hi all,
My first DIY project is going to be an integrated dac/amp to power a pair of small bookshelf speakers, fed by usb from a laptop
My list of parts so far:
1x ak4399 dac board with xmos usb chip + transformer
1x 6J1 dual tube preamplifier (12v input)
2x LJM L15D-Pro or CxD300 Class D boards
3x mains filters
4x speaker posts
1x fused iec socket
1x push button power switch
1x suitable aluminium chassis
I could use ideas of how to power the two amp boards and the preamp. Possibly a SMPS with additional 12v source. But which one? I am confused with regard to both which voltage would be required, and the overall power consumption and would like to keep this as cheap as possible in case i break anything.
