I found this - http://www.shop.com/op/~Sonicwave_8482_Glass_Toslink_8482_Cable_Gray_4023X-prod-32146388-41911410?sourceid=298 . It is available in lengths up to 5 meters.
I spent some time at the florida meet comparing Ray's R10s (serial number in the 1100 range) to a AT W11JPN and to my surprise the R10s had considerably deeper and fuller sounding bass with more impact. In fact the only pair of R10s I heard that were lacking in bass was an older pair that Mikhail had at the national meet (not the recabled one, he had two pairs at that meet). The rest of the R10s I have heard were the later production models and I was always satisfied with the amount of bass they presented. To me percussion instruments sound more real on the R10s than any other headphone I have ever heard.
Well I just put in my order for the extreme. I went with a Plitron transformer upgrade, Blackgates for the power and cathode caps, a gain switch, Solen stage 1, and a single tube adapter so I can use some 12au7, 12at7, etc. for the gain in addition to the standard 6sn7. I can't wait till I get this bad boy.
