@llkmi Simaudio Moon P8. Slightly warmer but it edged out. It was very hard to compare..the XP22 was excellent, airy, detailed, full of magical fidelity. The Moon just started whispering to the ear however . It was an unbelievable effect in the room that I could not recreate with any other preamp. Then, once I settled on the P8, I actually got a 850P on loan for a few days to see where this is going to go. It was also incredible in my new set up (i changed some other stuff around). The 850P was ’possibly’ even a tad more detailed....but I did not regret giving the 850p back (yes, mostly because of price). Bottom line, if you can get your hands on a P8 for fair price in decent condition, then IMHO don’t hesitate.
