Turntable Upgrade

Hello, " big enough " sounds like the operative phrase.
VPI's Cliffwood, with Grado-Green cartridge at less than $1000, might be a place to start thinking about what would make big difference.
It may be worth considering a Phono Pre-Amp and cartridge upgrade as a big factor also.

Under 2 grand!
Here ya go!

+1 on the VPI - that would be my choice in this "snack bracket"

Take a  look at - Music Hall models 5.3 and up

But for something completely different take a look at - JA Michell
