What Amp for ProAc Response 3's?

Hi; I'm currently running a Krell KST 100 amp with a Krell
KSL preamp via Cardas Hexlink Golden 5-c spkr cable to the
Response 3's.
My front end consist of a CAL MkII CD player and 80% of my listening are CD's. Musical tastes range from MOZART to BENATAR. Sound quality preferences; REAL,& HOLOGRAPHIC.
I'm looking to replace AMP and possibly PREAMP in the near future, for these units are about 12 years old.
Seeking some true Audiophile advice along these lines,
I've been out of the hobbie for awhile and a lot of models
have come and gone.
Special note: I am a "TRUE MUSIC
LOVER!"
Thank's folks,
MIKE.
