Bionic: Those sigma-delta DACs work like "steering" an analog voltage (the output voltage) by means of a 0-1 stream of -Vref and +Vref... this operation results in a situation where high frequency noise level and good slew rate would be concurrent parameters. As for the SID, yes, that should be the best. (Actually, it could be funny to emulate a SID to its full extent, including its true ~1Mhz operation... I don't think that it would be hard to in an FPGA, even if lots of multiplications must be done... hell, today's FPGAs have multipliers that execute 16-bit signed multiplications in a single cycle... =-) Actually, not even DACs capable of 1Mhz sampling frequency are expensive... :D )
