SS Pre amps Krell KRC-3 vs Classe 47.5 vs BAT VK


I have a Meridian 508-20, a pair of Mirage M3s, and a Krell KSA-150 amp running on a Bat vk3. I would like to change to SS pre amp as I need to leave the BAT on for awhile before it sounds good.
Any help will be appreciated.

Owned a KRC-3, most likely the worst sounding preamp on the face of the earth. Had a KBL (with a KSA-150), simply outstanding. Loved Rowland, currently have a SPECTRAL DMC-20 series 2, words cannot describe.

Good Luck
i have the classe 47.5 preamp w/phono board. I liked it better than other preamps that I auditioned that cost much more. Currently using balanced connections to cd player and to the amplifiers. Unit is built like a tank, and the sound is very smooth and detailed.
Auditioned a Krell KRC-3. Loved it. Ended up buying
a CJ Premier 14, but it was not a clear cut decision.
Very close.
