Fla, I have not tried the speaker cables. But I know they use the same cable for their interconnect, speaker cable and digital cable. I have tried it as an interconnect and a digital cable and in both the applications it is fabulous. When I say it is fabulous it doesnt have an wonder tone or a ghostly huge soundstage...it just sounds like it doesnt leave a signature of its own, the tone-timbre is dead on, soundstage is wall to wall when the recording has it else it is just nice and extends from outer edge of speaker to speaker. Background is very clean, not the kind of cleanliness which you see in some heavily shielded cables which almost always takes away something from the music as well. It is just very clean with all the music intact. Another outstanding thing about this cable is its PRAT. It is among the best in the business in keeping PRAT intact. Apart from all this, I have never missed anything in the detail department but it doesnt sound hyper detailed like some silver cables. IMO every little detail is there and presented the way it was intended. Clean taut bass and open airy highs with natural hue like an excellent tube equipment. In the end it sounds like nothing. You have to listen to this my friend.
