Audioquest colorado sound to bright

I agree with tooblue cardas cables will tame a foward or bright sounding system, and still sound musical warm and rich sounding. I use klipsch speakers and they can be bright and to revealing at times. I also use cardas cross interconnects. The cross interconnects seem to be the sweet spot in the cardas line.

I recently bought the Colorado cable ,and  spoke to one of their engineers 
The  dbs battery pack runs only a small electrostatic charge to block RF, And EMI
It doesnot breakin the cable . Give them 200  ours .I just played for 10 days straight night and day more refined and not bright unless the recording 
Is a very musical cable. Now discontinued  and can be bought for 1/2;thrir 
Original price .please note they should have the 72 volt dbs battery pack to 
Be the real deal not a phony one.

Earth is, I believe, the new replacement for Colorado. Earth has a smoother more refined sound. Also preferred it to the older Niagra  silver interconnects.

@mr_m  Have you had the opportunity to compare Colorados directly with Earth?  I thought the only appreciable difference was more layers of noise shielding in the Earth.
