What can I improve in my turntable setup?


Hello - I'm new to this group.

I think things should sound better, so the first thing I will do is see if I'm missing something obvious in the Turntable set-up.
I just moved into this new house.

The listening room:
It is a carpeted, finished basement equivilant to a large living room with a hallway that leasd to other rooms.
Basis 1400 Turntable... (no suspension)
Rega 900 Arm.....
Benz LO-4 Cartridge......
Nitty Gritty Cleaning machine
Decca Brush
Zerostat
LP#9 stylus cleaner.
Tracking at just under 2 gm.
Alligned with "Wally Tractor"

The turntable is floor mounted. It sits on about 100 pounds of cement. 3 adjustable bolts on the bottom of the cement block level the platform.
a 1/4 in. thick plexiglass dust cover covers the turntable and sits on weather stripping on the cement table.

I read that wall mounting a turntable has some advantages.
In my case - I think floor mounting is better because the concrete basement floor is pretty sturdy and will vibrate less than the walls (even though I bonded the wall studs to the concrete basement walls with expanding foam)

Any suggestions?

The first thing to insure is that the cartridge and arm are set up correctly. There are a number of tools that can aid this ranging from free (the stuff that came with the arm or cartridge) all the way to extremely expensive. The Wally Tracker, is that the whole set, or just one of the many individual tools?

Anyway, one of the less expensive options is the Mobile Fidelity GeoDisc. This does not have a set up device for VTA. If your Wally tool does that, forget what I said. All of these tools are intended to get you darn close to where you should be, the last fraction of an inch will be done by ear.

There are several books that can be very helpful too. "Good Sound" by Laura Dearborn, or "The Complete Guide To High-End Audio" by Robert Harley are helpful.

As far as tracking force goes, always track on the heavy side of the manufacturers recommendation. This is much less likely to damage your LPs.

There are some very devisive arguements about isolation as opposed to dampening. This will probably come up soon, from one camp or the other. The reason I bring it up, is you have nothing seperating your turntable from whatever vibrations will be present. Don't try to fool yourself into thinking they aren't there, or that whatever is there is soo small that it is not affecting your system. Think about how small the vibrations are in the groove of your LPs. Any vibration will affect the sound!

There is also the issue of 'airborne' vibration. They will also affect the turntables ability to accurately reproduce what is on the LP. Wall mounted shelves can be good if a person has a very springy floor. This is not the case in your room. Check into ways to seperate your table from vibrations.

Do you have any other tuning devices in the room?
