Using these as my main guitar/bass cables nowadays, both live and at my home studio.
From the minute you take them out of the box, you can feel (and hear) these are some of the best cables out there.
I've recently made the move to Vovox cables earlier this year, their line is absolutely amazing, but these in particular are simply outstanding.
Zero noise, amazing clarity, high signal, easy to handle, the list goes on.
As far as I see it, the only con is the price, as they are quite pricey, but most guitar players out there would surely agree that you should never skimp on the cables.
