Shelter 901 on SME 309 tonearm.
fiogf49gjkf0d
Good day, asking experts if it's worth mounting a Shelter 901 on a SME 309 arm. Resonance frequency shuld get upto to 12.86hz (being 17.6gr arm+cartridge and 9cu Shelter's compliance) which guess too high. Any guideline ? Many tks for advise. Ciampa.

I miss sometimes my Shelter’s viciousness…

Ciampa,

I am a huge fun of Shelter 901, love the cartridge, even I do not use it now but I would have no problems to continue use it. I do not about those new SME arms: SME 309, SME 4/5/6. I had once, sort time, SME V and I really did not “get” it. The tonearms preferences are a tricky thing and the things not always so clear.  I do not think that it was the SME V flat but the SME V was sitting right next to the SME 3012 and that made the SME V in disadvantage.

The resonance frequency – it would be strange for many folks but I do not particularly care about it. The rule of relation between the effective mass of arm + cartridge to compliance of the needle are fine but in practice I observed that they are not always have a direct sonic impact. For instance: the higher or lower resonance frequency might affect excitement of your lower end reproduction.  If you play better and heavier TT, do not play warped records and use DSET calcification in class A (the LF in-rash handled just by LF amps and not being intermediated into MF and HF) then you will less care about resonance frequency.

Still with Shelter 901 I preferred heavy load on my 3012. I think the default 3012 and SME 309 has the same effective mass – somewhere around 12g-13g. I do not remember the exact number but I loaded the 3012’s shell with extra mass, somewhere around 20-26g. Search the site, I even posted a picture of the shell loaded with silicone. I think you might try to add some extra mass to the cartridge and to see how SME 309 would response with sound. The Shelter 901 has phenomenal bass. With light arm this bass might be too “straightforward”.  Forget about the resonance frequency, your task is (at least my was) to make the Shelter bass more “complex”, very lash and in a way a bit slower then it is. I loaded 901 a bit harder (to 33K) and I played it with much heavier arm then a common sense would suggest.  I do not know how useful would it be with your TT, your arm and your listening preferences.

SME309.

Tks Romy, well...the SME has actually a mass of 9.5gr. Could eventually use a Micro MA505 with a slightely higher mass (guess around 11gr), have u ever tried it with the Shelter ? 
Was also wondering if the Ortofon T30 cd be used with some sense to charge either the 901 orthe 501. Am waiting for a new table, a Micro RX5000/RY5500 and wd really buy an excellent cartridge as the table may deserve...Ciampa.

I wish I was so smart at beginning…

I was stressing a couple days ago in Reed’s threads a point that the effective mass of tonearms itself is irrelevant for this type of cartridges.  There is absolutely no sense to change tonearm just because you would like to have “slightly higher mass” – add mass to headshell and it is it. if you are in Micro tables that have no tonearms length limitation then you might explore the 12” arms. With other equal conditions 12” arms sound way more superior to 9” arms. In my view Shelter 901 is a needle that deserves 12” arm… The 9”-10” arms are for TT with fix plinth. If you were stupid to get Micro then you need to have at least one proper (means longer) arm. I wish I was so smart at beginning then I would have all 4 SME-3012 on my own TT.
