I want to upgrade my Turntable to something heavier

all my comments are to keep your existing TT because you said

"I have a Pro-Ject, which I like a lot"

What specific model do you have?

Pro-Ject has Many TT accessories

btw, what type, how solid is your floor, your surface/rack the TT is on?

My wood floors are like a trampoline, so even though my Plinth is heavy, my rack level and solid, I had to add isolation blocks below my TT’s adjustable feet

I am using balanced cables out of my phono stage into my integrated. I like balanced cables better especially for a low level phono signal between the phono stage and preamp or integrated. My integrated doesn’t even have RCA inputs. 

That pro-ject x8 looks great. You should be fine if that’s the most you can spend. . 

I have had a VPI TNT III  for over 30 years, and it has been wonderful.

An alternative to another turntable is a better equipment rack.  I have a Mapleshade rack, and it provides a lot of isolation.  Check out their website.

@thecarpathian They are heavy and jump up into a specific chair. They don't care about the wooden floors. I am hoping a heavier TT will help with some vibration
