Tri-Amping with only one mass speaker cable?

213.47.56.5

Posted by qeter on January 11, 2009 at 07:39:41

Hello

I just transformed my hifi into tri-amping using Tannoy D700 with tweeter and super tweeter, middle driver and bass driver driven each by mono tube amps, needing in sum 6 tube mono power amps (3 for each speaker) at all.

I played a lot around with cables. And came to the conclusion that it sounds best to use only one mass cable shortcutting all the 6 mass outlets of the individual drivers and connect them straight away to the earth pole of the main earth outlet (that is connected to the internal masses of the pre- and power amps anyway).
This means I use from each power amp individual "+"-cables to the speakers (3 for each speaker - tweeter, middle, bass), but only one mass speaker cable. I save the money on 2 cables for each speaker. And to my ears the sound is more homogenious, too.

Does anybody know? Is there on clear physical (and not esoterical) reason why someome should use individual mass speaker cables for each driver, and not connect them alltogether to mass?
