Mastersound tube amps: 300b vs Dueventi
- Thread starter albymana
- Start date
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…

Sidebar 3: Measurements Measuring the Cayin A-300B was a more complex task than usual: The amplifier offers three different output-transformer taps and two different degrees of loop negative feedback, which effectively makes it equivalent to six different amplifiers! I took a full set of...
