I may try to do a comparison, but that table is heavy with that TNT platter and I hate fighting to get the ground wires attached behind the phono stage. The tonearm has two separate grounds and my anti-static brush has one too, when I try to attach the third, one of the three jump off. Times like that make me wish I had three arms...
When you have multiple ground wires to attach in a tight space, there are some easy solutions:
(1) attach any crappy old piece of zip cord to your preamp grounding post. Call this "new wire
(2) route new wire
to a convenient location on your rack. You can make it tidy w/ some duct tape.
(3) put an alligator clip on new wire
end. Also, strip off some insulation behind the clip.
(4) attach gear ground wires to this new wire
If gear ground wire is bare, attach an alligator to it, and clamp this to new wire
If gear ground wire terminates in a "u" connector, attach the "u" to new wire
In my rig I route new wire
to the front of one of my shelves so it can serve double duty as a human discharge station in dry winter conditions. Touch it before anything else in the rig, no more static shocks.
Oviously, you can locate the new wire
wherever you want, and the length can be whatever you need.
Your preamp's ground post should be able to accommodate this new wire
, plus a coupla others.
Here's another method I use that works great if your preamp ground post has a hole in the middle -- the kindof hole that accepts bananas. Get a few of these:http://www.monoprice.com/Product?p_id=9436&gclid=CjwKEAiAmeyxBRCJxoKk7IWLl2oSJABvZjhhGXwQjuD_jjxS55ySMnZNYHhNkEbRuZ1m1Gdi_i2zWBoCRvnw_wcB
Get cheapest ones you can find, definitely not BS audiophile grade! Attach one of these to each ground wire (it will accept bare wire and U connector), then plug one into ground post. The adapters have a hole on the end to accept other bananas, so they can be "stacked". With these, several ground wires can be attached / detached to a single ground post quickly and easily.
If preamp ground post hole accepts only bare wire, I'd go with the new wire
