I was using the Q-10 internal bi-wire for my HT fronts, now for the center and surrounds since re-integrating my two channel w/ht. The Q-10 is a very good performer for the price. Its open, detailed, extended, sounds fast, and yet is quite refined sounding for a cable at its price point. Response is flat with a relatively neutral sound, neither to bright or to warm. I also have Transparent Ultra XLs on my mains, and used to use Transparent Super on my center. The Q-10 is a little more open then the Super, although somewhat leaner sounding, but no less detailed or capable. I also tried Audioquest Granite and LAT International's top bi-wire cable. Neither one peformed at the same level, and both cost more.
