Integrated Amp Jumpers

Knownothing,

How ironic is your name compared to the insight you have provided (smiling). That was a great explanation! Thanks again.

Well, I will give one of the dealers I spoke with credit as he told me the King Cobras would have tighter, more defined bass response compared to the Diamondbacks. He was right about that.

As far as checking out various cables, my choices are none. Living in a small city means placing orders without auditioning first in most cases.

I will be on the phone Monday ordering a pair of .5m Diamondbacks for use as amp to pre-amp jumpers.

Excellent - good luck.

Now you should contact the Cable Company and check out silver fuses and an upgraded power cord for your amp if you have not already. Both provided improvements similar to higher quality jumpers, and for me the improvements were additive and synergistic.

I took the plunge on power cords a good while back. I am willing to give the caps a try. I would have to check into installation of caps since it doesn't look like a DIY project.

Caps - yes, silver fuses from HiFi Tuning or other source - no.

Nice post guys. I just gto done cleaning up an old NAD 3020 that may never have been opened. After cleaning it up and replacing the jumpers I am confident these types of signal/continuity changes do make cumulative improvements. I came across some audiophile hater site where nobody believed in such tweaks. 
Funny how this hobby can be so split, and helps me understand congress. For those who can't hear or believe in a symmetry between all the various parts in a stereo system, why are you hanging out trying to shoot us down from sharing information, learning and progress? Strange people. Not much faith. One pioneer of this industry was named " the man with the golden ear". He was blind, and only had his ears. He made some of the best sounding amps ever. I know one like this. He is a custom speaker designer that can match components by ear. Not everything can be measured. 
A tip for the non-believers: pick a time when no one is home, pick a time with no traffic to be heard, pick a time the fridge is not running, pick a time you are relaxed, shut off the fans, shut your mouth and listen. If you still think nothing can be improved on, your system likely sucks.
