OK, solved . Thankfully I have auditioned my own system in a nice, big room, and also trialed my RP10 in a friends system. I need to get my system out of my study!! The two systems used with my RP10 : triamped Accuphases, Accuphase pre amp, latest Perreaux phono stage , BMW801's, (the owners transrotor, Benz Ruby 3, Kuzma 12" to base-line)
Now , MY system :Naim Nait 5i-2 , Totem Dreamcatchers, RP10, Dynavector DV20X2. Perreaux phono stage 100 Ohm input 'Z'.
Putting the RP10 in my friends system: Every album is like listening to the musicians in the room. Pin point placement of instruments, as though everything was laid down in a single session. Amazing. Keep the transrotor and the Benz, thanks, I'm astonished at the RP10 and the Dynavector. When it wears out, I'll look a bit further up the market, but I LIKE Dynavector. A lot. Totem dream catchers are where I want to be. Pinpoint accuracy of tri amped 801's is missing, but boy, do I like what I have otherwise.
