Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

The basic difference between pcm and dsd for users

1. pcm has brick wall filter at 1/2 sampling frequency unless it is replayed without one, in which case supersonic noise is fed back into the chain.

2. pcm has poorer impulse response (transient) due to brick wall filter.

3. dsd pushes noise out beyond the audible region of frequencies but may upset systems with poor ultrasonic noise tolerence. Only an analogue and more gentle filter is needed following the dac. It has much better transient response.

There is no absolute superiority in either system.

My own leaning is towards 352k 24 bit pcm and dsd 128/256 for better sound quality.
