Do you need preamp or amp suggestions? I would go for a quality integrated amp with tubes, like VAC's Avatar. I think you will be ultimately disappointed with solid state gear, that is, unless you need a lot of power to drive these speakers in a large room.
I own a levinson 29 and am far from dissapointed,along with a tubed pre I am using it to run a pair of jadis 2 speakers with no complaints.I am unfamilure with how the krell sounds.
