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
ARC DSPre
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

@czbbcl what do you like about the Herron? I am looking for a 3D image, lowered noise floor, etc. thanks for the insight.
The sonic character of the unit is such that it is very true to the music and the recording. Very nice frequency extension on both sides of the audio spectrum along with a nice detailed mid-range. A strong performer and very competitive with units beyond its price point. It is easy to use and set-up with little fuss along with excellent support from Keith.

@adg101 Can you tell me more about what you like with the MW LS100? I am currently using tubes for power amp. Do you use this preamp and if so what associated gear is in your rig?
@czbbcl thanks for the details. Did you audition other units before purchasing the Herron? If so, please list and also provide details as to what sold you on the Herron vs. the comps. Thanks.
