interconnect brand/model attributes????

IMO it's unlikely an "unbiased" data base of the info you seek could ever be collated simply because a cable can sound variable with different components. Input impedance, sonic characteristics of speakers, cartridges, amps, etc. all alter one's perception of a wire's "sound." Since what one would consider a desirable cable is system dependent, Lloyd's answer is eminently sensible.

"Unbiased" opinion? Not a chance.

There are generalizations made such as cardas golden series are warm sounding, etc...

Understabding not all cables can be assesed on the same exact equipment, but, say two to three cables can be assesed by one individual with general characterisitcs noted.. If this could all be correlated into one site/location...

weeding through hundreds of gon pages---crazy

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.
