Lyra and OMA

Thanks to jcarr of Lyra for interesting information.

He wrote: "The Lyras will work OK in tonearms of 10~12g eff. mass (for example SME Type V, Technics SL-1200G), but will sound progressively better as the effective mass increases. Normally I’d suggest 16~18g as the sweet spot"

I run a Lyra Atlas (standard high output version) on a SME V arm. Should I add mass - even 6 g - to the arm?

Thanks for info!

@JCarr - thanks a lot for advice! I am now testing added mass to my SME V arm with Lyra Atlas. Ca 5g at the top of the headshell, 30g on top of the counterweight. This way, I did not have to screw the counterweight further back. I am using coins fastened with bluetac. VTF at ca 1.71g. Initial results: interesting. Some more bass. A sense of stability. Less hard/harsh treble, maybe. Sound a bit more soft, perhaps. Must test more. No clear minus so far - the cart tracks a warped LP ok. I should probably fine-tune weight,  oil chamber damping, etc. I wonder, are other SME/Lyra users trying this modification?
