Upgrade CJ PV11 or Acurus L10 or buy CJ Classic?

OK, looking for the next step on the road. Have enjoyed an Acurus L10 I got last year but think there is still better. Have heard the L10 can be upgraded by Ken Ealey to rival many $2k SS pres. Also have a friend offering a CJ PV 11 for $600 which also seems to be very upgradable. Is either path worth it or should I just go more modern and get a CJ Classic for $1500 or so? Will run with an updated MC250, Ohm 3-100s, CA 840C playing all kinds stuff from jazz to acoustic guitar to rock, singer songwriter, etc. I like the warmth of the Mc and especially the newer MC sound of the MC425 and the MA 6300/6600 but cant swing the upgrade cost. Keep hearing the pre brings more to the party than most understand and I feel i have never had a better than average one.Only other option to move forward in a cost effective fashion would be to start over with some kind of tube integrated like the Rogue Cronus Magnum or maybe a Creedk Destiny integrated....something keeping me around $2k.

Does any of this make sense? Suggestions? BTW, I live in Hawaii so I can hear virtually none of this before buying.
