I use a Rotel 971 cdp w/c has both digital & coax outputs w/c I pass to a Monarchy Audio DIP then MF A324 DAC before it enters my pre-amp. I compared Digital output vs Coax to DIP/DAC. The coax(75-ohm) has a warmer more analog presentation vs the digital w/c seemed dry/lean and uninspiring. The DIP is an anti-jitter w/c re-clocks the digital signal from your cdp. This smoothens the signal prior to entering your DAC. Yes, the effect of a DIP is noticeable.
