Dedicated line question

Tantejuut, where did you get this knowledge from?

A combination of 35+ years of audiophilitis, learning from other respectful audiophiles & manufactures (skipping the as^&(^&*es and knowitalls), EE degree, experimenting/DIY & common sense. 

Woah.....tantejuut....I just asked you nicely where you got this knowledge from, don’t be like all the other hare trigger jerk offs on this forum. 
I had never heard the term star quad before and I was wondering what field of electrical work it was from. Since you insulted me rather than giving me the answer I looked it up and I see it’s from the world of microphones and PA equipment. Could you give an explanation of how it works in a modern stereo system? I didn’t quite follow what you wrote. Thanks, Ray

My apologies Ray, I didn’t get the part where I insulted you. The part "learning from other respectful audiophiles & manufactures (skipping the as^&(^&*es and knowitalls)" is a more general complaint about hate trigger jerk offs in this hobby. I just wrote where I got my experience from. Please don’t get to personal.

Starquad works by magnetic rejection of external fields (self shielding). A good explanation can be found here:

The cable salad behind your rack is one big source of external fields. Starquad for low level connections is a must IMO. But it also works on power lines. Some people think it is only useful for long runs and strong external fields, but our systems can reach -90 db easily (at least when you measure it on the test bench). So every step in noise reduction can be heard. (blacker background, tighter/deeper bass, less haze). My starquad power line is hardwired directly from the breaker box to my distribution block, skipping connector junctions where possible. Then I use starquad power cabling to my system components. If I can’t use starquad (like UTP/SPDIF) I use double screened cable.

Keep safe and healthy. Juut
