Gentlemen, It has been several weeks now since the arrival of my new digital cables from Granite Audio and, as I felt that was sufficient break-in time, I wanted to post a few of my thoughts with regards to the #420.

I bought two of the #420 cables, one to feed from a Pioneer Elite DVD player into my processor and the other to audition between my Metronome transport and my Modwright MSB Platinum Plus DAC. This latter pairing was a bit of a lark as the XLR digital input of the DAC has been modified in a fashion which the RCA connection has not. But I wanted to try it out as I had high expectations, knowing the type of cables Granite produces otherwise.

The first swap was at the Pioneer set up. I have read reviews where the individual writes that a "veil was removed from the sound". Such was not the case here. I would describe the difference as more of removing a blanket. I didn't realize that the original cable was so dark until listening to your new #420. Keep in mind that this other cable was no slouch in its own right and had earned the right to be in my system. True, while I had always been impressed with the sound from this Elite unit on movies, it was somewhat less than what I wanted for music. No longer is that the case. I can honestly tell you that this cable made a bigger difference in my system than many of the mods I have had performed in the past. In effect, your digital cable took a mid-priced, mid-fi unit and managed to elevate it to a level of performance attained previously by modifications costing two to three times as much and taking weeks to implement. A better piece of equipment from a simple 5 minute change of a cable? Amazing! But the more interesting test was to be an unfair one, I felt. My reference 2 channel set up is tough to beat and one that I am very proud of. The Metronome is a constant and the Modwright MSB is a wonder. I had hoped the RCA connection with your Granite 420 would sound good, but I never thought it might best the modified XLR input. I will tell you it was both surprising and difficult to judge. Surprising because it should have been a hands down, XLR all-the-way show. Difficult because they were so close it took hours and hours to decide. In the end, I removed the balanced cable and kept the RCA connected Granite digital cable!

The soundstage was similar with both cables, both being very wide and impressive. But the voices were more distinct on the Granite cable. I found the sound to be very lively, yet not brittle at all. On some tracks, I felt the XLR input was slightly more articulate sounding on strings, but I attribute the difference to the modifications on the balanced side and not to the other XLR cable itself. It is my opinion that a balanced version of your #420 cable would be even better than this RCA version and, in my system, be the utmost in digital cabling. For your information, the XLR cable that you replaced was a high end, 99.99 % silver cable with some top-of-the-line connectors.

Thank you for your research and efforts on this cable, I know you have been working on this for over a year with several people pressuring you into getting to market, as it were. I can assure you that it has been worthwhile. I look forward to more of this cable making the publications and to hearing what some other more well regarded reviewers might have to say. By Walter S.
