Best phono stage for Lyra Etna SL cartridge?

Can you external load it and tryout some various loadings?If that works you be in for ~$15-20.

@chungih
Your phono stage loading available ranges from 14ohms to 200ohm and 47k.
The cartridge can run into any load more than 10 times the internal impedance - so you can safely load it from 20ohms up.
What Lyra recommends is that you try all your settings and use your ear to decide. You should try it at 47k, then 200ohms. If your prefer 200ohms then try going down below 200 ohms one step at a time to see if there is any lower load that sounds better. If not leave it at 200ohms.
There are no rules because the optimum loading varies depending on the phono stage you use.

For such a low impedance cartridge you may want to look at Transimpedance phono stages. These stages are said to mate well with low impedance cartridges.
I recently purchased a Sutherland Little Loco to match with my AT ART-9 (12 ohms) and it works very well. Sutherland also makes the Loco, Chanel D makes one as well, and other manufacturers. There is no loading with the stages. An internet search gives lots of info.

@sebrof  1+. Current mode is the way to go.

I thought that the impedance will control how bright or dark the sound is. I have slight sibilance that I want to get rid of, so I went to the lowest impedance of 14 ohms. I still hear some brightness. I can't lower the impedance anymore.
