Each of your upgraded kit has both digital and analogue processing - can you tell whether the improvements come from one side or the other? In other words, does either player sound better when you're using digital interfaces, as well as (presumably) analogue?

I don't really want to go OT, so I'm happy to go PM or a new thread. By the way, I did not mention in the PM, but Dave's upgrades are for both the audio (both digital and analog) as well as for the video reproduction. Yes they are most definitely better for everything after upgrade. Dave replaces lower quality parts with better parts where he knows their affect and they dramatically improve performance. He does not believe in replacing clocks etc.

Cheers, Nick

Hi Nick,

I just sent you a rather lengthy PM which I hope will prove to be valuable. I forgot to mention in the PM that Dave works on both the digital and analog sections of the audio as well as the video portion of the upgraded units. Dave does not believe in replacing clocks, or tubes mods. He replaces low quality parts with expensive high quality parts that he knows will have extremely positive effects from his 28 years of experience.
