Decca London Super Gold Compatibility Question

The first step is to try to tune the adjustment by ear with the existing arm, dialing it in by numbers is only the start. Once you've got it as good as you can get it then is the time to decide whether to try a different arm.

Thanks, I did that this weekend. I got it to sound ok but not great. My arm just isn’t right. Considering now a Moerch DP6, a damped unipivot, since I’ve really enjoyed that arm in the past.

I've tested the London Decca Reference on the FR-64S, FR-66S and DV-507/II and the FR-66S is undeniably the best match.

With both FR-64S and DV-507/II.....the Decca mistracked at the same point on every disc.
And I agree with previous posters.....the Deccas like their arms with the pivot slightly down.

Unipivots are not right for the Decca.  Lots of resonance reflects back into the arm....you need solid bearings.

A unipivot is what is recommended in the instructions that come in the cartridge box. Then again Art Dudley claimed to get good results with a maroon in a Rega arm. This with the addition of a Townshend outrigger and trough (the deck is a Rock mk2) was going to be my fallback if the Aro didn't work but what I'm hearing is tracking error at the start of the album not mistracking on transients. Getting the alignment to cross two null points rather than just failing to reach even one will deal with that but with an Aro that means boring a new arm board, fortunately I have a blank ready to go but the system is 800 miles away at the moment.
