For selling on Amazon speakers I ordered equal to 10 m of the speaker cables referred to herein (2x2.5) with. For the price is the cable OK! Plus and minus cables are marked. In any case, it has brought a significant improvement in contrast to the standard attached with the speaker cable. So I recommend it even further. Although this is probably is only a copper clad aluminum cable, there's no penalty. I think that one "household" is hardly or not tell the difference in everyday.
