No surprise to me. The American Digital is great for class "D" amps. What is special IMO about TWL products is that they are consistent in sonic character in ALL systems used.
Neutral would be my best description. TWL products are not tone controls. The cables do what a cable is required to do without adding or subtracting a thing.
Now if TWL would offer a all copper duplex outlet cryo treated of course we could plug copper plugs into copper receptacles oh my !!!. We need an TWL umbilical cable as well for those power supplies.
For all of you who have PIAudio Uberbuss or PIAudio or new Digibuss the All American digital cord is a must hear. Wonderful synergy with TWL products.
