At 10 meters in length, I had fears that the sound quality will suffer. But that is not the case. The sound is clear and strong. Compared to the coaxial cable also connected, gold-plated 1 meter long, I hear absolutely no difference. I run a Onkyo 608 in a 7.1 system with speakers in the price range of 4,000. This optical cable provides this despite the low price is no restriction. In contrast to coax it is also possible such long distances without loss of quality to be bridged. However, a prerequisite iat that the optical waveguide is not too tight out around corners.
Can therefore wholeheartedly recommend the product. For the price I have no choice but to distribute 5 star, due to the excellent price-performance ratio.
