Using long interconnects with your turntable?


I'm having some serious rumble issues with my turntable when I turn the volume up (Music Hall MMF-7 / Goldring Eroica high output moving coil cartridge). The rumble starts between 85 - 90 db.

I've tried everything from Mapleshade 4" block, to TTweights Isofeet, to a Ginko Cloud but nothing seems to help. The table sits on a Mapleshade Samson rack between my speakers. The speakers are roughly 4 feet to each side of the turntable.

I really don't think that the rumble is due to structural problems, I think it's acoustic in nature, because when I put my head directly over the table, I hear a bad bass node.

My two choices are to:

1) use a rumble filter (KAB?)
I'm not too keen on the idea of using a rumble filter, but I hear some positive remarks about this thing. Any thoughts on this?

2) move the turntable
In order for me to move the turntable, I need a 25 foot set of interconnects. I don't want to spend a ton of money, but I don't it to sound either bright, or rolled off in the top either (and I really don't want any noise or hum problems due to the length of the interconnects). I've read a lot of positive comments about the Kimber Hero. Any thoughts, suggestions and/or recommendations??

In advance, thanks for your input.

What about mounting the turntable on the wall behind the rack on a wall mounted Turntable ( Target type ) shelf???

Thorman,
The ceiling in my room is vaulted, so the wall behind the rack is only 4 ft high. In addition, behind the rack on the floor are two power conditioners. One is for my pre and power amp (Running Springs Audio), the other (Bybee) is for my CD Player, with all the cables behind the rack, the only place in the room for the turntable is on the side wall. I measured from the preamp to where the turntable would be is roughly 25 feet.
Elizabeth,
Now you're talking. That make's a lot of sense. Why didn't I think of that? I have a preamp (with the phono section built in), and a seperate power amp. I'm definetly going to consider your suggestion. Moving the rack (even though it will be a huge hassle because of the way my room is laid out) to the side wall should open the imaging, and, as a side benefit, give the room a new look. Great new thought, thanks.
By the way, how do you like your Hero interconnects?

Elizabeth,
Again, thanks for the suggestion. The more I think about it, the more sense it makes.
A radial engineering JPC stereo PC DI Box works well on all long interconnects.
