Wouldn’t the model with the heavier platter be best?
No
I don’t want to wrinkle anyones feathers but my GT-2000 is much superior sounding than the Victors! Something to think about.
Did you try same tonearm and cartridge on Victor and Yamaha?
Usually the GT 2000 comes with Yamaha tonearm, but what tonearm was on your Victor ?
Also I’m pretty you you can immediately notice the difference between cartridges, but not between different DD drives (it is much more complicated test).
