AlbertPorter is dead on, re "neutrality"!...............I'm trying a one meter Gold Eclipse III RCA interconnect right now, besides VERY many others. With either my tube power amplifier, or tubed headphone amplifier, I feel that it is very smooth, so much so that the treble range takes on (mostly) the same character, no matter which recording. All the other cables I'm trying don't do this. However, the GE3 is perhaps the least fatigueing silver interconnect I've ever heard (even though the treble range is still the slightest bit forward). It is a "very nice" cable, definitely worth the used price, IMO..................One thing I'm finding is that it is almost impossible to get that "tube midrange" that I'm after with a silver interconnect (my amp is NOT a 300B, or 2A3). However, this "midrange" CAN be had with my silver speaker cable (Dragon plus), provided the interconnect is copper...or perhaps gold..............Cardas makes "neutral reference" cables, and my experience with them has been that they are neither "neutral", nor a "reference". However, the name supposedly implies a consistent character, with regard to "no matter what length, they 'sound the same'". I have no idea whether this is true. It could be, I suppose, at least in a practical sense.
