ARC VT100MK2 substitute

Hello,

I would like to replace my ARC VT100 (year 2000) , because tired of expensive retubing and probably making the system too bright.
My system:
ARC LS15
AUDIOLAB 8200 CD
FOCAL 1028 BE
I am considering pass labs, plinius , anything else to suggest?
What’s the price i could ask.

Thanks a lot
