I've had the PV14L pre with the MV60se for about a month now, I use them to run my Quad 988. During the first few days of auditioning I thought that everything sounded recessed and the lower end was a little too rubbery for my liking, but I may have just gotten acclimatised to the setup or so but now my opinions have definately changed.
The midrange is superb, with natural vocals, unforced sound, lifelike perception of the music and staging. The upper register rolls off a little(but to my liking). The bass doesn't suffer from too my overhang anymore, though lacking in overall wallop is still precise and smooth.
I'm finding the longer I'm using the CJ combination the more I am enjoying the musical presentation and forgetting to listen to the sounds and trying to analyse but just having fun.
Hope that helps
