unsound - no doubt you're right. Jim gravitated to the Geortz from StraightWire. I think it was Tony Cordesman or John Atkinson who borrowed those Goertz for their reviews and considered them an improvement.
I haven't gone there myself because I prefer to stay in the middle lane with ancillary products that are likely to be in widespread use among Thiel owners and fans. However, I would love to audition some flat-ribbon cables for comparison.
My recent wire excursions have me cross-checking driving speakers with and without crossover networks. The SCS4 is quite well behaved with no XO at all. And, guess what, cables interact differently with bare drivers vs networks.
How would you characterize 'their very obvious differences'?
