Operate a Teufel system with this cable. Very good workmanship: plus and minus can be perfectly separated. Very good and harmonious sound also due to the cable, as pure copper was used. Delivered was not ready, but simply wound: but did not bother me. Only the somewhat strong plastic smell of the sheath bothered a bit, but I leave it as others simply airing a few days auf'm balcony.
All in all, however, a high-quality speaker cable that is convincing due to the price-performance ratio.
