Shelter and Triplanar matching ?

Doug

It happens (very audible ) with piano records and not during the entire side ( but almost every time at the beginning of each side) . When the sound of the note is going on after the attack it seems there is like a vibrato ( tremulous) in the sound .

I have tried a lot of different records like EMI or RCA or else.They seem well drilled but I will check it .I effectively never had the problem with extra flat DECCAS 200 g reeditions.....but I have a lot of records and they are not all Deccas 200 g

Perhaps the problem comes from records but the fact is that I did'nt hear it with the AUDIO NOTE.

I hope that increasing the quality of he cartridge is not synonimus with leaving the half of my records on the shelves !!!!

DOUG -

Thanks the detailed explaination and for the (R) formula, it was very helpful.

TENMUS - Tri-Planar supplies an optional "spacer" for their tone-arms. Get in contact with your dealer, maybe he'll throw one in for free!

Thank you DOGPILE for the suggestion.

Dogpile,

Excellent suggestion re: the spacer. The TP website even shows them, in black or silver to match the arm. Anyone whose armboard puts the VTA tower in the top half of its range should try one.

André,

Good description of the sound. That helps, and you just gave us three more good clues:
1) the tremolo occurs only at the beginning of sides,
2) the tremolo did not occur or was not audible with an A-N IQ-3,
3) the tremolo does not occur on 200g Decca reissues,

I have a hypothesis which explains #1 and #2. If it's correct then you should hear the tremolo with your friend's DL-103. (Make sure you set VTF to 2.2g or above, as the Denon prefers.) Let us know your results.

If my hypothesis is correct there are ways to solve the problem.

Unfortunately #3 seems to contradict my hypothesis. Do you have a 200g Decca with strong piano attacks at the very beginning of a side? If so, play that with the Shelter 901 and try to cue the stylus as close to the first music groove as possible. (I'm trying to disprove #3!) :-(

1) The Tremolo appears not only but ESPECIALLY on the beginningof the side but it may also happens at the end or even sometime in the middle of it.It seems to me that the problems comes with certain modulations and that it is amplified where the record is not PERFECTLY FLAT ( the beginning for example)

2) I 'll do the test with the Shelter/DECCA tomorrow morning.

Thanks

André
