Mastersound Tube Amplifiers from Italy



Mastersound 300B P.S.E. 2 Integrated Amplifier



January 2008



"With the Mastersound 300B SE and 300B P.S.E., you get Italian luxury - they not only look gorgeous, they are also excellent. In a way, they have the charm of a handmade product, not a large mass market sort of company. They exude solidity, it's a bit like the difference between a good suit from a department store and a tailor-made suit. And since they are exclusively tailored in Italy and nowhere else, they have their price.


The Mastersound 300Bs have a pleasant and sonorous tone reproduction. They have "more than usual" presence, which gives the music a strong expression. The quick and detailed upper bass presented rhythmic music that was involving and lively. And the "critical HighEnder" may be surprised to find that fine nuances of bass solos are revealed by the Mastersound. In any case, I was.  Bass is accurate and fast-paced.


The midrange of the Mastersound is "exceptional"- it will draw most listeners in its spell. Immediacy, proximity and intimacy in the vocals draw these amplifiers from - and the abundance of timbral complexity and shades that are revealed (especially with acoustic instruments) is simply astonishing, amazing.


The tweeter is the same caliber. Soft, silky and detailed. The reproduction of sheet metal drums can trigger deep bliss. Depending on the speakers, the spatial representation is a bit of a "bigger than live" syndrome. It is the winking invitation of a charmer to the listening pleasure. And I must concede that this works pretty well ...


The Mastersound 300Bs have an incredibly strong sense of presence in the musical performance. Nothing here is washed out, but that is exactly what threatens so little of the music. I believe it is a very difficult balancing act - the MastersounD masters with flying colors."



The Mastersound 300B P.S.E. 2 tube integrated amplifier, where P.S.E. stands for Parallel Single-Ended and 2 means Mark 2, offers more power in an integrated amplifier from the Mastersound Compact 300B, for those who need it.
