I love them. They were, however, beaten by the (far more expensive) Cardas Golden Cross in my system. I prefer the AP Oval 9 copper over the AP 12 gauge silver hybrid in the systems I've tried them with. Oval 9 is very natural, rich, with deep bass. Treble detail and extension nd speed are natural as opposed to extreme as in some cables or gear. I feel that the Cardas Golden Cross was more refined. Also in a head to head comparison with Harmonic Tech Pro9, I personally found the AP a bit more natural sounding. The HT had a little more speed and treble detail but to my ear was just a hair less natural. I could be happy with either of these though.,
