Best 300B SET

I don't know if this is how other tube types react since I have only heard 300b in my home, but with my 300b implementation the more complex and layered the rock music the more the layers of sound texture float into my listening space. Reverb and harmonics are intoxicating and rock guitars are loaded with harmonics so they are particularly beguiling. The louder I turn it up the better this music sounds.
Before I decided to go with 300b tubes I was concerned if they could play all types of music. With my listening tastes and priorities 300b works well.

Jet,
Our experiences are similar regarding 300b amps.My prior amplifier was a very good 100 watt(60 watt triode mode which I preferred) push pull class AB 6550/KT88.I wondered if the 8 watt SET 300b might let me down in some areas while excelling in others.It exceeded expectations(stunningly so) and the bigger push pull amp was retired long ago.
Charles,

Edoit, I have thrown you off topic. Your original inquiry is to pair a Shindo pre with a cost no object 300b amp. Please hear the Shindo 300b amp with the Massetto. System synergy - at least that is a place to begin.

Jetrexpro,

in your mind, what would be a matching, current production speakers for the Shindo WE300B?

Edoit, I would first look at Shindo speakers and also Devore speakers. I have heard Devore speakers with Shindo electronics and it has always been a very musical experience. Some folks have paired Shindo electronics with Audio Note speakers. Do you have speakers already? If not, I might suggest you begin your system search by finding the speakers you love and building a system around them.

Charles 1 has had great success with an all Coincident system. Other have had success with all Audio Note system. Both of these companies make excellent speakers and 300b tube amps.
Charles or others might comment on how they arrived at the speakers they fell in love with. For me I could have more than happily loved either Devore speakers or Audio Note. There are many speakers I have not heard as well that would work well with 8 to 10 watts.
