Having only recently discovered the extremely impressive performance of the TT2, the next logical (?!) step was to hammer the wallet once more and go for an m-scaler...(courtesy also of the current virus situation misery lol).
Anyway, being slightly concerned by the number of folks stating the almost obligatory need to have top grade digital cables, which can indeed be silly money, I myself feel much happier knowing one can make one's own fairly easily for not a lot of money. And having found superb results first for connecting my Naim UnitiCore to Hugo2, and now to the TT2, I shall of course be repeating for the 2x BNCs of m-scaler.
Although unconventional for a 75 Ohm requirement, I and a very exacting fellow DIY head-fier friend (with far better hearing than myself!) progressed from using
Neotech UP-OCC silver and copper wires for interconnects/headphone cables/power cables, to applying same to digital cable. And much to both our surprise, it easily surpassed my previous use of 1.3mm solid 'ordinary' pure, soft annealed silver in place of a coax cable's copper.
But this time, instead of conventional coax cable as the carrier, I used (modified) cat 7
Ethernet cable! By removing its 4x twisted pairs from their foil shielding, one can replace with the already teflon coated Neotech cables. I personally used 2x silver and 2x copper, but a lower AWG in just one pair would probably be just as good. And I also - hating connectors with a vengeance - dispense with the plugs' pins and fashion the wires so as to act
as the pins and make direct metal-to-metal contact in the socket...far more preferable IMHO!
Given the much higher frequency transmission capability of such cable, it was a pleasant surprise to discover just how well it aided performance, despite perhaps not quite being the exact SPDIF impedance requirement. No doubt the additional (thick) foil shielding around each conductor, as well as the outer braid help no end in interference suppression.
And so perhaps fellow DIY cablers (and would-be ones) might want to give this method some thought...especially as it's a relatively easy procedure, and one that I'm sure can result in a cable to rival (or exceed!) commercial ones at many times the price...
A photo of the blank cable I used first, but for the m-scaler will use cat
8 cable out of interest :
ps. The twisted pairs are easily pulled out with pliers, and then try not to pinch the cable, so avoiding compressing the foil conduits too much....GOOD LUCK!
