Bang for the buck


I've got some money to spend but it must be spent wisely. I would like to know what would give a better result. A new tonearm or a new platter/clamp?

I have a Gyrodec SE with an Audio Note Arm One and new Sumiko Blue Point EVO III.

Looking to u/g the arm or platter or possibly only the clamp. Any suggestions on which would give me more sound?

Plus 1 on the room treatments.
Theres not enough money in the world to spend on equipment, that a room correctly treated will accomplish.
How do you know he's not listening through headphones? Yeah, get some room treatments. Get some new shoes while you're at it. Couldn't hurt, right?
