modern turntable or old school dd


I own a vintage system. A Marantz 2270 receiver,Technics sl-1600 turntable with a Grado green cart and klipsch kg-4 speakers. My question is this. Would I notice a difference in sound quality if I upgraded the Turntable to a entry level Rega or a Project turntable ? I love the Technics unit and am having no problems but sometimes I feel like I'm missing something.It seems as if these new units are so simple they have to sound better. My vinyl is in great shape with many records being 180 gram new re-issues.

I have owned (3)Rega p3, p5, Music Hall 7, Linn Lp12, (2)Systemdek IV, Thorens TD160 HD. After a conversation with a guy that purchased a couple cartridges from me at my house, I got curious about DD tables since I had never owned one before. I now have a technics SL 1200 M5G with KAB fluid damper,Applied Fidelity improved main bearing, Ortofon HMC 30 Cart. I love it and would not trade it back for any of the previous tables
Modern, unless you like the old school look, and depending on what grade with that, haha.
