Wilson uses cj amps amongst many to voice their speakers. Mr johnson of c-j uses a wilson personaly at home i believe. My sophia 1s sound great with my cj pr 12 monos now that i have faster chryoed kt 120s in my amps. Every upstream change can be heard on these revealing speakers. got great results chryoing my hovland 2 phono cable, seems a lot of what i did not like was not do to the speaker which is only 5-6k used, a nice bargain in todays market
