Manley 300B preamp


I have ordered and am waiting for the arrival of a dream object: Manley Neo-Classic 300B. While waiting I thought of inviting owners of this preamp a thread where we can hang around for the latest news. Please feel free to describe it's sound, matching in your system, experience with different tubes etc. I would love to read about your experiences while waiting: then at least I can do some virtual listening ;-)

Yes, I am gaining some impressions of Manley Neo-Classic 300B. When I change a component I always get sensitive about a couple of things and I have then to listen for a long time to get the nuances. And I'm not a guy who changes gear often. 

The preamp has played around 110 hours. So it probably still need some breaking-in. However, it doesn't seem to change as much each day now.

My first impressions is that this Manley 300B preamp interprets the signals from the source in an authoritative way: it portraits music in a bold and dramatic way. Music is played with dynamic swings, both in micro and macro parts. The timbre of instruments and voices is rich and organic. Yet, the most unexpected quality is that is more transparent than my last preamp: Leben RS-28CX. This comes forward in a clearer presentation of low noises in a piece of music but also a more holographic and dimensional projection of the music into my living room. 

Musically the 300B satisfies me immensely. It seem to have the magical qualities of the 300B tube, but playing together with the Snappers it really rocks: plenty of bass, slam and drama. So this match gives that midrange magic with a lot of power. And speaking of midrange: voices just stand out of a band. It is so clear, natural and with an inner glow. 

I think I've become manleyfied: 300B and Snappers are staying.
As always with a new tube amplifier I buy a spare set of tubes. Even if Manley stuff is seldomly stable, it is part of living with tube magic that you need to change a tube once in awhile. And you don't want that to happen after a nice bottle of Pinot Noir is opened and some pals is digging into the new tune of some fave artist.

Any advices on a tube setup that has good synergy with this Manley preamp. I'v been reading about Shuguang Treasure series and TJ mesh plate. But what about the other tubes: 6SL7, 5AR4 and OD3? Any experience with what of all the combinations that works together?
My Manley 300B preamp is retubed as follows:

EML (Emission Labs) 300B (solid plate)
Japanese (Mullard copy) 5AR4
Tunsol NOS 6SL7GT
Philips OD3

This combination has worked well to take the preamp to an even higher level of resolution and dynamics.
Thanks Fwinston. I'll check them out. Any other experiences from other users of this preamp?
I've retubed my Manley preamp to be synergistic with the retubed Manley 250 amps running Maggie 20.1. I realized early on that I could make some significant changes in the sound and found a match that works for me. The amps are running:

SED EL34, GEC A2900, RCA 12bh7 blackplates

The 300B preamp now has:

EML 300B Mesh, Philip miniwatt Metal base gz34, Brimar 6sl7gty and RCA OD3.

Still have a set of Western Electric 300Bs, but the midrange was too rich and colored. The EMLs really clarified the midrange.
