Help me make the best arm-cartridge matches

Thanks for the responses. I purchased the two different cartridges due o their different sonic characteristics (I like variety). From what I had read previously, the Decca cartridge does best on a damped unipivot arm and is very sensitive to VTA and VTF. I understand the S7 arm is a unipivot, but I don't know if it is damped in any way. I guess I'm wondering about two things: 1) I should put the Decca on the S7 or on another unipivot such as a Graham that is more easily adjustable, and 2) How does the Koetsu do on unipivots in general and the S7 in particular.

Dear Thsalmon: I insist, a little, that the manufacturers ( tonearm and cartridges ) must be your first advise step.
The second step should be your own experience: with your SY working with both cartridges and " see " which one ( maybe both, we don't know yet ) makes a better SY match ( here it does not matters if the SY tonearm is or is not a damped one or if it is unipivot or not ). Ovbiously that for test this second step you have to have a music reproduction reference fromm both cartridges for you can find what you are looking for.

The third step could be to try in other tonearms and here there are several options, from the Moerch to the Schroeder or Kuzma and other like: SME, Brinckman, Phantom, Audiocraft, Ikeda, Triplanar, La Luce, Naim, Pluto, Linn, etc, etc...

Regards and enjoy the music.
Raul.

Buy the Schroeder and Allaerts. I use mine on a Platine Verdier with GT Audio Battery PSU. I also have Deccas, albeit much older ones - an original Garrott Brothers Gold and a Maroon. The Allaerts MC1B just destroys my deccas - shame as I have been very fond of them for over 20 years.

If money is no object, buy a Schroeder Reference or SQ (special quality) and an Allaerts MC2 Finish or Formula 1. The good thing is that if you don't have the money, you've got a 6 month wait to save up after you've placed your order!

I waitied for more than a year for a Schroeder Reference SQ. I just cancelled the order. Prepare to wait till you die for a Schroeder...

For the Decca, Ken Kessler has stated he has used the Decca in a SME V to very good results and also the VPI 12.5 tonearm with dampening (the 12.6 no longer has dampening capabilities!?)Raul has also recommended the Ikeda in another post on 12" Tonearms....
