Shopping for a preamp

I’m in the market for a preamp. I use a Rogue Cronus Magnum Integrated. I have been looking at phono-pre’s which is fine if I use my integrated as a line stage and power amp. I am also thinking long term so I may be best suited to buy a preamp with built in pre and add a power amp down the road. Budget is between $2,500-$4K.

I've had my eye on:

Herron VTPH2
Whest Three Signature
Pass Labs XP-15

I welcome all recommendations on those listed above as well as for other phono-pre’s or for a preamp with built in phono-pre.

My set-up:

Rogue Cronus Magnum
Zu Soul MkII
VPI Scout 1.1
Soundsmith Zephyr MkII
Zu Cabling
My amp is the Pass Labs x250.5 and speakers are my dear old B&W Matrix 803 s2.  I'd say dynamics and musical realism are the Ref2's strong points.  I've owned 3 tube preamps (granted, not very many compared to many others here) and it combines the "tube magic" with a dynamic punch that I haven't experienced with other tubed preamps.  For me it's the best overall performance I've had in my system (although no tubed unit is as downright quiet as a well designed solid state pre). The Ref2 is a clear and definitive step up from my Cary SLP-98 F1 and two steps up from my ARC LS-16mkII.
I think I may have misread your requirements.  Are you looking for a preamp with a built in phono stage? If so, then the Ref2 is not what you are looking for because it is a line stage and you'd have to add a phono stage. BTW, I like your Pass XP-15 choice, those are supposed to be incredible.  Pass phono stages are highly thought of. So are their XP-10/20 line stages.  In your budget I'd also look at a used XP-10 if you want a great line stage.
@abrew19 Thanks, yes I am looking for a preamp with phono. I really liked the New Record Day review of the Pass XP-15 and he too uses it with a Cronus Magnum so although the source and speakers differ, there are still some parallels. I auditioned the Rogue Ares tube preamp and I just didn't care for the tube on tube. Too much for me. I enjoyed an SS phono-pre matched with my tube power amp. 
Thanks everyone for your input. I've decided to audition the Pass Labs XP-15 and the Herron VTPH-2. Mark at Reno Hifi has been very helpful and Keith Herron called me directly to discuss and we had a great conversation.

i should have the Pass by next Wednesday and the Herron shortly thereafter and will provide a critique once broken in.

Incidentally, Modwright never got back to me.

Hi ASP:  What did you decide between the Pass Labs & the Herron?  Oh, I see in your short list was the Whest.....did you get a chance to hear that?
