OK- I managed to obtain a pair of Cardas Golden Reference IC's(along with a GR PC) and have to say that yes, indeed, I can hear a clearly increase in bass. Meaning I can clearly hear the bass, but "feel" more of the bass too. Now, I had a Shunyata Copperhead PC on my Pass amp and when I hooked up the GR IC's I have to say it was not a discernable change. Hooked up the GR PC AND the GR IC's and ,yes, definitely a change. However, soundstage is totally different than the HT Magic II's. More recessed, I think. I also feel some of the detail is missing. On certain solos, I can tell the placement of the soloist is moved. What was once centerstage is now recessed. Now, I have to say I don't know if it was intended to be recessed or centerstage, just that that's how it sounds now. Personally, I think it was intended for center stage. But, that's me.So, while the Golden References did, in fact, give me more bass extension, I am looking to other avenues. I am thinking Purist Audio Venustas or Synergistic Tesla Accelerators for IC's from preamp to amp. I just feel something is missing. Don't get me wrong it still sounds wonderful. Guess I'm just a brat...or very hard to please.
