Best phono stage for Lyra Etna SL cartridge?

The best is a Herron VTPH-2A. But since you can’t get one new, you’ll either have to find a used one or settle for something... less.

Very nice cart. Not the same league but I have a Lyra Delos running off of a EAR Yoshino 834 MM/MC and I'm pleased. From memory I believe the impedance is about the same between the two carts

My local dealer has installed a number of these cartridges and recommends 0-50 ohms of loading for this cartridge. I almost purchased this cartridge  - it was in the final 2 - but ended up going for a Grado Aeon, which is simply gorgeous

I found the Lyra particularly smooth. Having a smooth type phonostage may be a bridge too far

To get the best out of a very low impedance cartridge go for one of the phono stages that automatically adjusts. 1,2 ohm is not articulately low, but the voltage is. On the other hand they have a relatively high milli ampere output that just needs to be amplified.
I am using a Van den Hul "The Grail" but there are cheaper options!
I think Michael Fremer has lookrd in to this! Just Google.
