@awise1961 A very interesting observation, in that you own both but prefer your LP12 over your P10. If you don’t mind sharing, why specifically does your LP12 bring you more joy?
The LP12 with the AEON 3 has that midrange bliss with very good bass and upper end detail that suits my ears well. My other setups are wonderful as well with the P10 providing more detail and still great bass. The Rega RB1000 is a great tonearm. I like the LP12's Lingo 3 power supply. My TT power supplies get installed behind the door in a salamander cabinet. When I want to pause the LP12, I use the swith on the TT itself. With the Rega, there is no such swith on the TT. You have to press a button on the power supply which means opening the cabinet door and first moving any LP's which may be waiting in the wings in front of it.
I'm listening to Steely Dan Gaucho via the LP 12 as I write this and it is beautiful
The rest of my system consists of a Conrad Johnson TEA3 phono stage into a CJ GAT S1 preamp into CJ LP276M tube monoblocks into Wilson Alexia speakers. Al cabling is Audience Front Row. This all resides in a dedicated listening room which measures 23' X 25' with a vaulted ceiling.
In this system, for me, the LP12 is very musical.
Your system will possibly invoke a different outcome.
