Tried many dig cables with the Dip. Canare, MSB cable, Monster, MIT, to name a few. I gave all these cables away after using the Kimber D60 and KS2020. The Dip is a great little dig processor that most likely will improve your sound from Transp to dac using just about any of the less expensive 75ohm dig cable like the Canare. But I found that the better dig cable like the D60 and even better KS2020 just pushes the envolope further. The cost of the cable will exceed the cost of the Dip. Is it worth it? To me, yes it was. I also use a Classe Transp and dac. The SuperDrive Dip is better than the reg Dip. The SuperDrive has the same Opt and RCA coax inputs but substitutes a BNC output instead of the AES Bal out on the reg Dip. They both also have the standard RCA coax out. The SD Dip adds 3db of gain only on the BNC out (said to be for long cable run up to 100ft but works good for 1m or like0. I use two Dips, one for the CD and another for my Satellite receiver with opt dig out. Here is where the bigger difference is found in using a Dip. Using the OPT out from the Sat receiver into the Dip and out of the Dip using a D60 into the Classe dac. The Dip converts the OPT out from the Sat receiver and sends the data to the Dac using the D60. This has enhanced the sound of the Sat system greatly. The Dip also has enhanced the Transp to dac, but only slightly. From Sat, the Dip has really showed it's magic. You milage will vary with what transport and dac will be used. The better the trans and dac, the less the Dip is going to do and guess to a point where it may be a step down. Using with a Link Dac, yes, the dip will help.
