Qualitatively sure beyond all doubt, but Overkill

Sure, subwoofers are the type speakers, where cheap stripping bring degrading sound quality with it. This cable is qualitatively the most highest quality speaker cables, I've ever had in my hands.

Nevertheless, I see it as overkill. It is extremely thick and inflexible and not exactly cheap. Oehlbach gives it 5 stars (that is the best thing they have). If I take the 4-star Oehlbach I hear no difference, do not pay quite a quarter and have a significantly more flexible cable that fits in my cable channels in the living room.

Conclusion:

At the cable should not save, but this here is going too far. My chain of Marantz SR6006 AV Receiver and devil THX Ultra 2 speakers is not sufficient to justify such a thing.

4 stars because it certainly a top cable, but point deduction for the price and because it is extremely large and stiff.
