Thanks for sharing your musical preferences. That allows me to better understand your musical perspective. I understand that you want a system that reproduces every nuance, as if you are in the orchestra with the musicians, along with the microphones, and the Lyra Atlas definitely makes me feel that way, and I understand why you have such an affinity for that cartridge. On the other hand, the Koetsu does make you feel like you are further back in the audience seating, where details are lost, but some people think the sounds combine more musically the further back you are from the orchestra / musicians. Your perception is that this effect of the Koetsu is s a deficiency, and technically, I suppose you are correct.
As previously mentioned, it does seem that most experienced audiophiles do prefer a SS phono stage, and I am looking in that direction. While I haven't researched all the recommendations yet, I would say that I'm preliminarily leaning towards the CH Precision P1 with X1 power supply.
Thanks.
