interconnect brand/model attributes????

Well why don't you start out by telling people what your gear is, what cables you are currently using and then telling us what you think is missing. Are you looking for someting with more musicality or something with more resolution?

There is no site that has what you are asking for, just as there is no map the can tell you how to get from 'here' to 'there'. However, there are experienced people here who can help guide you, they just need to know where you are at presently and where you want to go.

I've heard the Kubala Sosna Emotion, they will give you more of a 3-D soundstage than the Gabriel (Rapture), but I think they will actually have less high end extension than the Gabriel. I haven't heard the MAC Pallidiums.

I don't know what your price range is, but the best interconnects I've heard as far as 3-D staging AND high end extension are the Stealth Indra or even the Metacarbon if the Indra is out of range.

Dvdgreco, I would say that tonally they are similar, the GG Rapture's may be slightly more extended in the high's and the K-S fuller in the bass. As far as soundstaging goes, the K-S had a deeper more 3 dimensional stage, more similar in this regard to Purist Audio Design cables.

Cardas, Purist Audio Design and Kubala-Sosna sound like what you are looking for if you are looking for more vibrant tonal colors, musicality, bass weight, a deep 3-D soundstage.
