Hi Greg, the Bottlehead and CSP have the same DAC topology the differences are that the CSP is JUST a squeezebox player, the BH does USB and S/PDIF. So if you are a SB person, going with CSP gives you a more focused option. For the BH DAC the filter parameters are built in to the FPGA, you can't change them, for CSP the filter is done in software on the wandboard, you can change the parameters via a webGui any time you want. On the PS front the BH comes with a battery which gets the best out of it. The CSP has a jack, you can plug whatever you want into it. I had not thought about using separate supplies with the CSP. In order for it to work there will have to be some changes to the board layout and some way to select single or double supply. There is no way to do this with the boards as they are currently layed out. I will have to think about this one and see if there is any way to do this.
