Thank you!

I use identical tubed mono power amps. And as I can see from the internal circuits of the amps the input ground is connected to the output ground as well as all grounded caps and resistors and the earth pole of the mains power supply.

The sound is for sure better with the ground of all drivers connected to a central ground post at the earth pole of the main plug. The sound is then "one sound". By connecting the grounds individually onto all 6 power amps the sound does not come together to one picture. It overemphatises the different instruments as stand alone and all in front. With connecting all grounds together the soundpicture becomes one picture with width and depth and more musicality, like everything plays "in phase".

Do you think my installation can be dangerous if for some other reason a shortcut happens? That the main fuse or fuses in the amps might not blow?

Thanks a lot,
Peter
