Connecting monoblock tube amps to single subwoofer.

Hi all,

I have added a REL5TX sub to my system which is driven by VTL225 monoblocks.Currently the sub and amps are connected via the low level outputs on my preamp. I would prefer to use the high level connection to the REL by direct  connection to the the VTLs. I am concerned about creation of a ground loop that will cause hum on the system. I have been told that the ground loop can be avoided by running a ground wire directly between each amp. Is this a possible solution, and if so, where / how should the ground "jumper" be connected to each monoblock?

Many thanks in advance for any comments or suggestions.

The answer to the question is to add a second REL T5x to the system. This way, each sub can run off the particular mono block. This is REL's advice and it is well given. The addition of a second sub to my system is a nice benefit when it comes to overall bottom end resolution. 

One thing to consider, the addition of a second sub is exponentially harder to set up, with the blend and the correct positioning than just one sub. Given enough tweaking it works out well, but time and patience will be required to make it work.

I figured REL knows their products a lot better than I do. 

@ ieales:

Possibly.

Oh no sir, Not "possibly" but absolutely.  I can assure you that REL does indeed know their product a lot better than I do.  :)

One more thought which has usually served me well is to apply the principle of  Occam's Razor.  I paraphrase: "Generally the simplest answer is the best answer."

Not always. of course, but often enough. YMMV.  :)  And  of course, some anal-obsessive audiophiles are likely to surely disagree.  :)

OTOH, I'm with daveyf, I eventually got a second sub, even before swapping my mono tube amps for a tube integrated.
