The best digital IC, period.

There are 6 different guys with very good systems but we all prefer the HiDiamond Digital Carbon, Power 3 power cords, Signal 5, 7, 9 and speaker cables D4, D7 and D8. We all have several different systems so depending on if the system is in our main listening or just a secondary system. If I had to pick one series I would pick their series 7 speaker cables and interconnects with the Power 3 power cord and Carbon Digital. Sound in my opinion is all about reproducing what the recording studio intended you to hear and HiDiamond cables do that in our systems but it is still just our opinions.

I am not sure how much honesty you are looking for but please remember this is just my opinion from blind test results. We have tested Ridge Street and they also tested well but we were never looking for OK we are always looking for a new reference. I would personally say if the cable company does not a real factory or a metallurgy background probably stays away from that manufacturer. I could build a good cable with a nice sleeve and market that cable but who really cares. When you buy a cable it should have little to no effect on your equipment; you should never us a cable as an equalizer. You will know the cable is correct when you become emotionally attached to the artist. Cables with bloated bass or cables that are too analytical will not allow you to connect with the artist.
When we test digital cables it is always 1.5 meters unless the manufacturer recommends a different length.
There are 6 different guys so the source and DACs vary when we do our test. Several of the systems are very expensive and do have what we consider reference components. The equipment will definitely affect the results of any test.

Ozzy, no, the six foot cable lacked articulation and sounded a bit too warm for my taste. Your system being different than mine may not have a problem. Measure exactly what you need to the inch, HAVE will custom make you a cable without extra cost, just tell them what you need.

Audioengr, $685. I'm trying to share my experience that a $25 can, and most likely is, nipping at the heals of such crazy expensive cables here.

There is no definitive "best" of anything. There are way too many variables involved. The "best" you can hope for is to find something that works well in your system. You can then say it's the "best" for you until you find something you think is better !!!!
