Atmas-phere MP-3 MKIII --- opinions?


This is a follow up to my previous post:

I'm leaning toward the Atmosphere MP-3 MKIII to replace my current solid state preamp.

Preamp: Musical Fidelity M6PRE (to be replaced)
Amp: Musical Fidelity M6PRX
Speakers: Vandersteen 3a Signatures
Analog: VPI traveler turntable with Ortofon Bronze MM cartridge
Digital: Ayre CX-7 CD player

Lots of good reviews for the Atmas-phere MP3. But I'm also reading that the power and V-cap upgrades are essential, the phono section is noisy and the system is sensitive to power cord changes.

I guess I really want to get the Atmas-phere and am hoping folks here can share their experiences to help me decide. Or other comparable tube preamp suggestions?

I'm thinking:

Sutherland 20/20
Lehmann Decade
Pass Labs XP15
Allnic H 1201
Manley Labs Chinook
Parasound Halo JC3
You can buy any Atma-Sphere preamp as a line stage and add the phono section later. In the MP-3, the phono costs $800 to add after the fact.

Our UV-1 has gotten some nice comments from customers comparing it to phono-only sections that cost several times more than it does. Set up for LOMC cartridges it retails for $2800 so its within the budget.
I've had Atmas-phere equipment on loan in the past. Had the 60 watt mono blocks in the system for a couple of years even. I've heard two of Ralph's pre-amps in the system too. Gorgeous sounding equipment. I say go for it ... it will blow away the solid state pre-amp in terms of realism and tonal correctness.
The other day after dinner with friends in Atlanta we went to one of their homes, where we demonstrated the Atma-Sphere UV-1 in his very high end system. The preamp acquitted itself very well even before being warmed up. They will have it for a few more days to try in their systems.
