Can a modern arm beat my MAX-282?

I recently had the oportunity to pick up an Air Tight PC-1 Coda for a great price and have been very impressed with it's performance over my long-time cartridge (Shelter Harmony). It's gotten me wondering how far I can taky my vinyl rig.

I'm currently running it on my Micro Seiki MAX-282 with the J-shaped arm.

I'm now wondering whether the arm could be holding things back. The MAX has never been a popular arm, but I've always been happy with its performance. I'd love to hear what folks here think a modern arm might bring to the system.

I'd be consdering things in the range of the 4point 11, Reed 3p, SME Series V, etc. I suppose I'd also consider a 3012R or FR64, since I've never heard these arms.

I'm curious if this would just be different or if I could acheive a broad improvement. Any thoughs?

My deck is a Micro RX-5000 Air with the BA-50 base and my phono stage is an Accuphase C-47.
