The Classic offers no significant improvement over the Aries 3 - you might go backwards.
The weak point is the VPI arm - why don't you look into upgrading the VPI arm to a non VPI arm & new cartridge on the Aries. That will give you maximum improvement for the dollars invested in my view.
The AMG Giro is underwhelming - very smooth, but lacking punch and dynamics, despite being better built than both the VPI's.
