Importancy of DAC's analog section

I think both of you make excellent points. Leaving aside the subjective side, I'm curious about the measurements. If you take a look at a reference input vs. the output measured on the same scope, how similar is a scope load vs your own system preamp input's? I suppose they are both high inpedance but I wonder how the load affects the dac output. You can find some excellent DAC measurements both in jitter and noise floor as seen on the spectrum analyzer. I wonder how this translates to the actual sound. I assume good measurements are at least an objective way of seeing how good a job the DAC is doing.

One of the things that the modification people are replacing are the output OPamps chips in the analog section of the CD-player/DAC. These OPamps are often of inferior quality. It is better to replace those OPamps with good sounding ones or to use discrete OPamp modules. What is rationale of using the most advanced DAC chips and algorithms but to implement cheap bad sounding OPamps? To those "high tech digital audio" manufacturers: We (audiophiles) are interested in sound, not technology!

The digital section used to be the most important factor during the infancy of CD technology. But now pretty much everyone from $100 Denon CD player to a high end design uses state of the art BB or Wolfson DAC. I agree with others, the analog section is much more important now that the digital section is more matured.
