SoundSmith Rega combo

Thanks Matt, hoping to not having use a spacer and don’t want to change the counter weight 

Take a look at these links
https://www.vinylengine.com/tonearm_database.php
https://www.vinylengine.com/cartridge_resonance_evaluator.php

The effective mass for the tonearm on the P3 in the database states 11.5 gm

The cartridge Compliance appears to have two values 22 and 28 uN - I’m not sure what the really means - are there two versions available for order?

The P3 arm has an effective mass of 11.5
The Cartridge has a weight of 6.8 grams + mounting hardware - provided the total does not exceed 8 gm

Using the evaluator, from the resulting chart it would appear the the 22uN would be suitable for the arm - it’s just in the green

It would appear the 28uN version would not be suitable

The Irox Blue might be a better match

My Audiomods arm that uses a rega arm tube  has a list of compatible cartridges - see

I just hope I've read everything correctly - Steve

Thanks for the links Steve, I heard from Peter himself and says, may not need it. Im gonna go ahead and order the Cart, I think it will make the best synergy/balance for the P6, I don’t really want to go to MC cart at this stage

Hi guys. When a 3mm spacer is installed on a 2016 Planar 3, will the lid be able to close?

I agree that no spacer is needed. I used a Rega RP-6 and Soundsmith Boheme, and sounded best without it. The Carmen and Boheme have similar cart shapes/sizes.
