mastersound SET amps from Italy

Believe it or not I'm driving my 81dB efficient MBL 101Es with their 20 wpc 300B integrated.
I will be ordering a pair of their monoblocks but I won't know which ones until I hear one of their 845-based products.
Though 20 watts are not enough for my speakers, these are the finest amps I have ever had in my house.
I should note that these 300B amps produce a very clean and powerful sound, they are not warm and fuzzy.

Has anybody compared any of Mastersound's 300b-based offerings with one of their 845-based offerings?

Hi, may I ask: does this SET amp sound like solid state? I'm asking because some of you don't like the typical SET sound and prefer a neutral, fast and dynamic sound with good bass like... solid state sound. So why are you buying a SET with "only" 20W/pc while you can buy a good sounding solid state amp with 150W/pc for the same money and without the tube hassle? I hope I'm not offending anyone. Just curious.

Dazzdax,
First up, I'm not buying the 20 wpc amp, I am going to buy either their 40 wpc or 117 wpc monoblocks. I just have the little integrated amp on loan.

This amp sounds nothing like typical solid state and very little like premium SS.
In my current system I have been through the following amps (in reverse order of preference):
Manley Neo-Classic 250 monoblocks (250wpc)
Atma-Sphere MA-2 mkIII monoblocks (220wpc)
Hovland Stratos monoblocks (640wpc)
The Hovlands, by the way, are the only SS amps I've ever liked.

If you've seen any of my 'odd' postings about the sound I'm looking for then you'll know that I am fanatical about spatial presentation.
I haven't thought in terms of "neutral, fast and dynamic sound with good bass," for years. I just think, 'am I in the presence of real people playing real instruments in my room?' Or, better still, 'am I in the presence of real people playing real instruments in their room?'
The Mastersound 300B has the most natural, room-filling sound that I have ever heard. It's a simple as that. Everything else that I gain once I get a proper linestage and phonstage hooked up to their monoblocks will simply be gravy.

Exlibris, what do the Mastersound 300B mono's cost? Do you know their 845 mono's?
