Anyone NOT like the sound of VPI?

The SDS should be your next purchase. They're commonly available used here for +/- 700.00, and will have an immediate, and positive effect.

As an experiment, try using carpet thread instead of the rubber belt from your motor assembly to the platter. Helps to tighten up the musical presentation. Do a search at
VA for different knot-tying methods.

Johnbrown, I have the SDS and converted to thread drive. This did not greatly change my perception of a relatively lightweight bass. YMMV

Madfloyd, I sort of missed it, but you're wondering about the Rega. I formerly had a Rega P25 with Grado Sonata, Sumiko Blue Point Special, ARC SP9 MKII, Pro-ject Tube Box, always thought that bass somewhat lightweight as well. The Tube Box improved that deficiency to some extent, in the end I blamed the tt.

I also currently have a highly modified Thorens TD160, this does give me a more satisfactory tonal balance. Unfortunately, it not in the same class as the VPI in the resolution department. Still, I would describe it as more musical than the VPI in it's current state.

I urge you to give that Nordost wire more time to break in. Get back in 6 months..it takes a very long time. The notion that the VPI table is inherently bass light is ludicrous. I have bass on mine that can shake the house. I doubt if wall mounting will make any difference for you. The VPI benefits from the SDS, the heavy platter, the ring clamp, the MInt protractor etc...however these just make it better. The table you have is quite wonderful if set up correctly. Call VPI and get their take on this. They have always been responsive and excellent for me.

Madfloyd, MDF does not make a very good platform, though I doubt it would suck the bass out of the system. It will make for an uninvolving sound however. Maple makes for a good platform. I use a maple platform on a sandbox with a separate platform for the motor. I agree that the platform material makes a difference in sound.
I do not agree that the upgrades are necessary to get good sound from the ScoutMaster. Mine is relatively stripped down except for the signature arm and I have never had the bass problems you are having. AAMOF, the bass response with the Dyna 20xl was superior to that of my cdp which is known for its bass qualities. This is what makes your problem hard to diagnose.
There are those who do not like the VPI sound. But it is usually a PRAT issue rather than bass or midbass. AAMOF, I think that VPI is somewhat known for its bass response.
