SoundSmith Rega combo

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.

Update: I was advised by my retailer that whilst its possible to fit the "Carmen" to a Rega arm its fiddly, you do infact need a spacer, if you want to close the lid (which I do) you have to get the Tungsten counter weight, also if the rake angle needs to be adjusted, you need to use fine slivers of business card or some such, (the rake angle advice came from Peter Ledermann himself) my retailer has been doing this for 30 plus years, so I listened to his advice and went with the Ania cart for now, Im gonna save for a TT that has adjustable tonearm height, in the meantime I have a P6/Ania combo to tie me over, hope this helps
