Shelter and Triplanar matching ?

I would be pleased to have your opinion on this precise point regarding only the best way to make the 0,24 mV version working fine .

There's a useful preamp gain calculator on this site:

It will help you estimate the necessary gain for any cartridge. (+ or - 5% from their recommendation is fine in my experience.)

In this case, a 0.24mv cartridge needs approximately 63db of gain before the line stage. A 1:10 SUT provides 20db, so your MM phono section must provide the rest. If your MM phono has about 40-46db you'll be fine.

Thanks for this usefull info.
My Jadis JP 80 provides 48 dB , so it should work even with the 0,24 mV version wich seems the best choice according your review.

My old c-j PV11 provided 47 db, nearly identical to your Jadis, and my Bent SUT's are 1:10. That setup was fine.

Your gain control will probably be fairly sensitive, but having ample gain from the SUT keeps tube noise low. It was a good tradeoff in my system.

Do you know what could be the consequences if matching an Airy 3 SILVER version with a COPPER SUT ? or the opposite?

André

Dear Doug: With al my respect to you and trying to help André and to you:



- The André audio system is in the 50K range price: Verdier, JP80, JA 200, Triplanar, Shelter, etc, etc.



-The André Jadis preamp was not designed for low output cartridges , it was designed for high output ones: this is a fact.



- You are one of the regular to this forum and I think that you want to help André given him your best advise and in my opinion you are not doing that.



- You are supporting a 600.00 dls solution ( the worst/wrong one. ) for a 50K audio system and this is not fair for André and the music.



- With that " worst/wrong " solution the André audio system quality sound reproduction will belongs to that un-named " worst/wrong " solution ??????? This is a big mistake. Of course, André can take it, is up to him.



- The JP80 was designed for MM or high output MC cartridges and out there there are several great high output ones that beats easily your supporting " worst/wrong " solution.



- MM from Ortofon, Music Maker, Rega, Goldring, Grado, Audio Technica, Sumiko, Clearaudio, Roksan, Reson, etc, etc. and high output MC from: Sumiko ( the Blackbird is a champ ), Clearaudio, Allaerts, etc, etc.





André, if you really like/love music ( and want to hear in all " glory " your Jadis electronics instead of one additional transformer: step-up transformer ) and take care about music my advise is that you could think for a moment in the MM/HO MC option that is not only the best quality sound reproduction solution but less expensive that Doug alternative. As I told you: is up to you and your music priorities.



Regards and enjoy the music.
