Offline, go for a tube preamp. Just make sure the output impedance is low enough to drive your Krell. I was never a fan of Krell preamps. My experience with the KRC, KRC-HR and KRC3 is similiar to yours plus a FLAT soundstage.
I'm a big fan of Krell amps though. I've own a Krell KSA100s, FPB300 and FPB600 with only positive experiences.
Krell cd players sounds great but had a reliability problem with their Philip transports. My KPS30i and KAV300cd spent most of the time in transit to and from Krell for repairs or replacement.
