Todd, Did you assemble this "system" yourself? I'd like to get into DSP, but is it really necessary that I spend >$1K to have such a system? I have an AT compatible and I really don't need to have a stand-alone system (like yours with a serial port). Does anyone out there have a 56001 system running on an AT platform that they built/bought for under $1K? Does adding a second pair of ADC/DAC's for stereo increase the cost/complexity a lot? Since I don't have any 56000 data sheets can you tell me what's the difference between the 56000 and the 56001? Thanks for any info! Cliff
