How Good are the Analysis Plus speaker c

I have the ultimate way to determine how good stereo "stuff" is. My wife has great ears and moderate interest in listening. She also pays the bills and the agreement is that I can't buy anything if she doesn't hear a difference (with at least some positives). We've been doing this for many years and I have come to trust her less invested but more objective input. She loves our Quad 63's, partly because they can't go too loud but also because of the usual Quad attributes. We were running 15ft AT Dragon from a Sonic Fronteirs Power 2 which most would agree is up there with the big guys/gals. It sounded as one would expect, great. I happebn to know the guys who developed AP and had always been curious. I accept that bias could be seen here but my wife has never met these guys. We (I) ordered a pair to try and went through the effort to A-B the cables. It was actually one of the simpler changes to evaluate. The AP silver cable sounded better in soundstage which we had preceived to be excellent. Quads also tend to be laid back but the AP brought a new sense on "life" to the sound with a "reach out to you feeling" as opposed to "here I am, come on in." While they are incredibly cheaper, there value is incredible. They didn't blow away the Dragon but were significantly helpful that this was a no brainer. One previous writer questioned the bass and since the Quads are crossed over at @100 to Celestion 6000 subs, I can't comment but am curious. Having listened to many of the great cables, and frankly being able to afford, within reason, what I really want (read NEED), these are a real bargin that loses nothing that I could hear. My wife also finds them to act as I have described. And yes gentlemen, there are women in this world who actually listen to the high end and while not her favorite thing, she does love the music and tolerantly enjoys the stuff that makes the music. Well, there is at least one woman so there must be more.
