VPI Scout or GEM Dandy PolyTable

Go with the Scout.  I have had mine for over 10 years and everytime I think about changing, I ask myself why.  The Scout is built to last a lifetime.

Any reason to not look at the Scout Jr. As an option?

I would upgrade and modify the 150 and you'll have a table that will be as good and maybe better than both. However, if you must part it either table is nice and should be auditioned. 

Btw, f you want to sell your 150, contact me.

@raymonda thanks for the insight... you might be on to something. I really do love my TD-150. It is completely refurbished, and has a custom walnut plinth to match my amp/phono pre.

The biggest frustration I have is not with the table but with the footfall I am getting due to it being on a wood floor, on a crawl space.

I am going to look into some ways to improve isolation.

Maybe something like this to get started: http://herbiesaudiolab.net/compfeet.htm

Use a stand that you can bolt to the wall. Rega makes a nice one. Also, changing out your tone arm for a better one will go a long way towards improving your sound.

Jelco and Rega work well and will fit the size of your arm board. You'll need to replace your arm board with a new one to drill it for a proper fit.

enjoy.
