Mastersound tube amps: 300b vs Dueventi

Anyone has any experience / compare with another amp in that price range, the EAR Yoshino 869? Thank you in advance
 
Apologies, I haven't heard the amplifier in question. I use a VTL ST-85 and am very happy with it.
Found this on the EAR 869 however...

It was engineered by TdP, so likely more trustworthy. The circuit diagram posted by @Chr1 shows some VERY clever ideas including a starved-plate cascode and screen drive of the output tube. I would hazard to guess that its performance is significantly better than the junk stuff discussed earlier.
 
Why not buy a properly designed 300B if you must have 300b.

I had this one and with Emission Lab 300B and current production Tung sol input stage the distortion was halved compared to Stereophile data.
I have not seen any single triode amp perform better than this

But since then I changed speakers and 300B became too weak…
