Lyra and OMA

There are calculators and there is experience. Maybe JCarr knows a little ;)

Care to elaborate on arm and phono? Might get more details that way

According to OMA website it is 1:10. From a gain perspective probably OK with Kleos 0.5mV, although would be curious about the Aric 6sn7 gain. Might the Kleos sound better in this system with  lower ( numerically ) load? Maybe. Could require some experimentation.

Can't comment on synergy with Project arm, 8.5g eff mass on the light side. I do think Lyra carts are sensitive to both arm synergy and setup and when both / either is wrong you get that ' analytical ' sound. 

@michaellent I know you want to know why. Its a big topic. Lets just say that in this case many decades of experience are speaking :)

Tonearm has a lot to do do with how much you get out of your cart...
