Acrylic platter


I have a Project expression II turntable which comes with an aluminum platter . I was wondering on buying an Acrylic platter made specifically for my turntable . My question is will it make a difference for the better changing my aluminum platter for an acrylic one ? I'm using an Ortofon Salsa moving coil cartridge with it , project speed box , cables are JPS superconductor Q and phono stage is the dedicated moving coil gold phono board of the Audible Illusions 3A preamp .

Thanks a lot guys . My preamp is excellent in it's sound quality and even though I could get better sound with another cartridge my present cartridge is an over achiever for the price so the law of diminishing returns comes into play . To get me better sound I would have to invest an amount that at this time is prohibited (unless I'm willing to sleep with my dog)
I've read quite a bit on the subject and it seems that a consensus is starting to form on the positive sonic qualities of metal together with cork or acrylic . Getting a acrylic mat seems to be my best option right now. Again, thank you guys for your help . Take care
This is just a matter of opinion. My opinion is that acrylic is not intrinsically any better than alu. The early Teres turntables used all acrylic platters, and the recommendation was for no platter mat. Then they went to acrylic with pockets of lead shot imbedded in the acrylic. Then they went to wood platters on their top of the line turntables. I am sure, if queried, Teres would say that each "upgrade" was for the better. When I see an OEM turntable with an acrylic platter, my first thought is that the platter material was chosen for looks, ease of machining, and low cost, not necessarily for max performance. My question would be why would you feel confident that acrylic is better than alu? I would suggest using a mat on the alu platter, rather than exchanging the whole platter. Boston Audio Mat1 or 2 is very good. But that's just my opinion.
I have not said that I feel confident that acrylic is the way to go . If that would have been true I would not be asking here and just would have gone and bought the acrylic platter .

I have heard turntables that came with metal platter and I did not like the results when it was changed for acrylic . The same is true vice versa , so it seems to be a matter of the overall system synergy . In any event the only way to find out if I would like the results is to test it in my system .
Sorry, but the very fact that you are entertaining this expensive change in platters made me think you were entering into it with the bias that acrylic would be superior to alu. Anyway, you asked for opinions, and you got opinions. I would sooner experiment with platter mats, if for no other reason than the cost factor.

One bit of caution: you probably want to be sure that any new platter is not too far different in mass and circumference from the original, for three reasons: (1) the motor was probably chosen and tuned to move the mass of the OEM platter, (2) if the tt is belt-drive or rim drive, then the motor pulley circumference was chosen to give the correct speed when coupled with the OEM platter circumference, and (3) an excessively heavy new platter might cause premature bearing wear.
Lewm...thank you for the sugestions . I'm more inclined now to experiment with mats instead of going straight for the platter .
