I think Lyra does most of things but think for speed it truncates decay which is why, whenever I have heard it, and this is in many systems with valves and SS, CH, Ypsilon, pass, naim phonos, I have appreciated how music is presented but never become involved. Dynamics, speed, detail, resolution, extension, has always been great.
Opus was clearly better in Gian's system, immediately, on all the classical records I played. More natural, better stage. On an attribute to attribute basis it would lose out on speed, extension, and dynamics to the Lyra, but would still be better... That's the problem with trying to write why vs listening.
It did not have a midrange bloom. But then I think zyx while it has a nice midrange does not have a bloom at the cost of other stuff. Koetsu and madake do. And zyx universe premium at Steve's is far from dull. So there is some system mismatch
Will Opus be a cart that Is complete? I don't know. It might still not be sufficient, but then will all others. It will be more complete than Lyra based on listening in Gian's system. That's the problem with these carts. Spend so much and it's not complete. It sounds better than GFS at Gian's too, but may or may not do so at Mike's.
If you ever go to audio arts in N.Y. The Allaerts to me is a complete cart, outside Mike's analog set up, albeit with less resolution than Lyra (like all other carts), plus a price am happy with. This might change over the next three months as I compare it to more carts.
