levinson 26 to replace adcom 565

would you purchase a Levinson 26 in which the Camacs were changed professionally to Rca's 

To put it simply... YES.  It is a common practice to swap them out for RCA's.  

Camac connections were a nice idea (i.e. the negative connection disconnects before the positive side when pulling the cable out), but it never caught on.  

@canefanmd yes to the Levinson, its a iconic preamp. 

Well the unit was bought and hooked up definitely different sound  right now heavy on the bass still need to change cables and cartridge but Im happy 

Glad your happy with the purchase.  Out of curiosity, how is the Levinson working with the treble on the Adcom GFA-555 and the Heresy's?  The Adcom amps of that time always sounded harsh in the upper midrange and treble to me. (I always called it "twizzy".)  The GFP-565 seemed to roll off the top end which tamed it somewhat.
