upgrade or replace rega planar 3

The upgraded Rega has been compared to the Sota Star Saphire by someone who owns a Sota Star Saphire and it came out a draw. Since you have the rb600 arm, it is absolutely worth it to you. Not only that, but Rega is better for jazz than Sota.

I'm a jazz fanatic, and I have a P-3 24 with every Rega tweek known to man.

Inna, my Rega P-3 fit your description, it was flat, until I replaced the tonearm wire, the motor, the sub platter, the acrylic platter, and installed the heavy weight arm balance; after that, it sang.

Inna, you're right, it was about 1K. We set the bar so high that it's very hard to reach.

Manitunc, the Sota Sapphire is a fantastic table with a good suspension. The person who made the comparison was someone who had tweeked the Rega with the same tweeks I made. That should be here on the "Gon". When the tonearm wire is replaced with "Incognito" and the sub platter which uses a "Sapphire bearing", plus acrylic platter, plus "Techno heavy weight" arm balance, plus the P-3-24 motor; which is much quieter than the stock P-3 motor, you have an entirely different P-3.

I only record, and I use my Rega on the concrete basement floor. This negates the need for a suspension.

I agree with your statement in regard to the stock P-3 and the Sota Sapphire.
