Great thread!
@anthos314 I have used three different Lyra's over the past several years. I started with a Delos, then an Atlas and now an Etna SL. Haven't had the chance to listen to a lambda version in my system. They all share a "house" sound and the Delos is an amazing cart.
I wanted to briefly address the issues that you and others with Lyra carts have brought up, the unique sound of their carts and the impression of being a little lean in sound. While I don't disagree with adjusting your cartridge loading but this has a very subtle effect with my phono pre (PASS XP-27). I have found that I get a more full bodied sound without sacrificing the amazing top end clarity when I have the SRA/VTA optimized. My lyra is mounted on a Kuzma 4point 9. I use the Wally Reference tools to find the level at which the cart is parallel to the record and then a USB scope to adjust the SRA to 92 degrees. When you get the SRA close to 92 degrees, you can make further small adjustments by listening. You will find the meat on the bone you are looking for.
Enjoy.
