Do any of you know/have FMS Grey Speaker Cables?

I think Ladderlake has the original "FMS Grey", not the grey jacketed "WaveGuide" Kjweiss is describing. The design is similar, but not the same. The "202" version of WaveGuide is the best sonically. -AG

The FMS "Grey" SC is from the late 80's. It's very well made with "FMS" helical serve conductors in OFHC enamel coated wire with TPFE tape dialectric. The design was for AudioQuest but our relationship with AQ (1983-1987) ended before the cable was made. AudioStream (Paradigm Loudspeakers) licensed a version the design made with bare copper and sold it as Audiostream Black. Changing the construction from enamel coated to bare copper did not have any sonic penalty, which surprised me (and Bill Low). I kept working on the design with bare copper, and in the early 90's it was manufactured and sold as FMS WaveGuide, first "102" then "202". Many miles of this cable (2-15,000 ft runs and one 25,000 ft. run) have been sold. The "202" is the best of all of them. It is much more transparent (Harry Pearson definition) than the others. This gives it a 3D realism that goes beyond not only the previous versions, but most of what is currently available. I have been in demo rooms and heard 202 embarass $10K cables.
