This probably belongs someplace else. but I can’t find it, so here goes.
This $119 item gets as much big-time productivity enhancement as anything I know. It’s a 3 foot Glass Optical Cable with 470 strands of real glass fiber–as opposed to the usual fiber and glass combinations. As I recall, it’s imported from Germany, where it was originally used in surgical/medical applications (and maybe still is). Anyway, it makes the garden variety optical cable–a la approx. $25 bucks from Crutchfield, Amazon, Audio Advisor, etc.–sound veiled. The increase in clarity, detail and overall sound quality is huge. I use it in several different audio systems around the house and in each case the improvement is like orders of magnitude better. And that’s using several different DAC’s (two RME ADI-2’s, two SMSL SU-8’s, two Bifrost Multibit’s, one Bifrost Uber, and one Modi Multibit) in headphone systems, main speaker systems and a near-field speaker system. I got the recommendation for a “real glass” digital cable 3-4 years ago from a tech support guy at AudioEngine, when I was building the near-field system with 3 of their speakers and 2 from Focal. It made a big difference and I’ve been using the same brand cable in other systems ever since, including to replace existing coax cables from Cardas.
Here are the specifics. Company name is Lifatec USA. www.lifatec.com. 315-689-1497. Cable name is TOSLINK-TOSLINK SILFLEX GLASS DIGITAL AUDIO CABLE w/OPTISILK SHEATHING. This is a great little company in the Finger Lakes region of upstate New York. And this particular cable has a “30 day, 100% satisfaction guarantee, no-risk return policy.”
You might want to give this Lifatec a try, especially if you’re currently using a mediocre coax or optical cable…Lee
