Looking for a tube preamp to pair with CA 840W

Price limit: $2500.

I am using a Cambridge Audio 840w Solid state 200wpc power amp. The Conrad Johnson 17LS looks pretty nice. Does anyone have any other suggestions?
Audio Valve Eklipse with NOS tubes is outstanding. See review on here. Stunning build quality and open soundstage. Has been rated above the Conrad Johnson by some reviewers
I replaced a CJ Premier 17LS2 with an Aesthetix Calypso and couldn't be more pleased. They show up frequently here on Audiogon at ~$2500.
