What cart. for the Reed 3P?

Like Chakster implied, it depends on the effective mass of the Reed what one would recommend, because each Reed can be had in something like six different species of wood that vary quite a bit in density.  I have a Red Cedar 10.5-inch Reed 2A (about 12-15g effective mass) currently running a Stanton 980LZS, which sounds so good that I have been too lazy to try anything else for nearly a year now.

guys thanks-sbank thanks - funny Doug is who I got the Reed from and just bought his Lyra Etna- Just need to have someone dial it in for me- Hope it is a killer combo- To all thanks for helping a newbee out!!

Dear lewm: At 15grs. your LZS  resonate at 6hz, not so good, and at 12grs. the frequency is a little better: 7hz.

With that cartridge as higher is the tonearm effective mass as lower is the frequency resonance frequency: not good for the listening quality level .

Anyway, the important issue is that you are very satisfied and this is your main target.

Btw, in that resonance frequency regards the 3P/Etna is in the " ideal " frequency range., good.

regards and enjoy the music,

@rauliruegas do you use online resonance calculator or you’re talking from personal experience?
I was quite sceptical about optimal performance of Stanton 980 LZS on my 18g Reed 3P Cocobolo "12 untill i received my cartridge and mounted it.

From my experience all those online calculatora are incorrect and i don’t trust them. I only use Hi-Fi Test LP to measure actual resonance frequency of cartridge/tonearm combo.

Don’t forget about this special brush on Stanton 980 LZS - this is really works well with 2 - 2,5g tracking force. So my samle of Stanton in actual lateral/vertical resonance test (with Hi-Fi News LP) stay between 10-7Hz!
Again: Tonearm effective mass is 18g

Maybe suspension is a bit stiff as the cartridge looks unplayed NOS, we will see after some hrs with Cardas Burn-In record. 

Dear CH: I think that this audio subject is not about to trust on something or not. It is just mathematics and you can use any calculator over the net and will gives you the same resonance frequency ( 6 hz. ). 

What we can't trust is in a test record that comes with " natural " errors " from the recording process and during playback. This is what I don't trust, mathematics are just mathematics and here it's not a " rocket science ".

Regards and enjoy the music,
