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.
