You mean downgrade the preamp to a valve based one.

I thought someone would say that.

And *your* advice on the original question is...?

Fix the active speakers, add a subwoofer and an active crossover
to fill in the missing two octaves, compare the CD player with a new one
to see if it needs upgrading (it won't).
Rewire the preamp to get rid of any tone controls and other crap
in the signal path and possibly add a new phono preamp
(I don't know how the old Meridian 101B sounds.)

Will that do?
