I do not know what Bit DAC's you might be using ,but upon inserting the DAC with the new Canare Cable into the loop I was able to discern that some of the underlying Details that I was missing were more apparent!The effect is not astronomical,but it is there!
The most important improvement that I noticed was a better presence of Cymbals and Voice info is more distinct.
I will also point out that this is inserted in to a system which only had a 16bit stock Phillips DAC!Anything just about short of getting a Custom Powercord would probably be an improvement.
Another fact I will mention is I only had time to play 4 tunes that were fresh in my mind from listening at high Vol. yesterday as a good reference .The amp was cold and the CDP \ART DAC were on for 10mins so that they could warm up.The sound is rather sterile until my system has a chance to get warm so these are just initial impressions.The DAC and the Cable will also need time to burn-in for the sound to warm up.
The DAC Mod.\Tweeks would probably help also.If it was voted as being used in the playback at CES for Finest Sound Booth at the show there must be merit in using it .For me it was worth it!
Later!
