ICs with great natural sounding highs?

XLO Reference/Signature

Currently, my interconnect of choice is the Ridge Street Poiema 3, which I've owned simultaneously with the Cardas Golden Reference. Depending on the mix of components at any given time, I could live with either, however, the Poiema 3's more revealing top end does add a welcome measure to my musical enjoyment. To my ears, it also sounds somewhat more neutral vs. the Cardas, however, I can easily understand why some others might appreciate and prefer the Cardas. It is a very, very fine interconnect. I also owned the Synergistic Tesla Accelerator. Despite both considerable burn in on my Hagerman Pro Frykleaner and listening in my system, I did not find is as satisfying as the Cardas or Poiema. But, again, personal reactions and tastes will vary.

I've been using Kimber Selects(KS-1130), and found them to be VERY transparent. They will allow whatever your source is capable of to pass without hinderance. Some look at interconnects as a tone control. The interconnect SHOULD not affect the signal at all. At least; That would be the ideal. If your reproduction is not accurate with these cables: The fault is elsewhere in your system.

Cardas Golden Reference is very good in this area but some will say its too slow. I agree with Rodman99999 about the Kimber Select 1130. The Kimber Select series are all wonderful and priced to suit anyones needs.
