So, as I wrote earlier no chance to use Master in my Niagara 5000. So I decided to compare QSA Violet vs Master in my BHK pre. I burned in Master for 3 days without any listening sessions and need to say that Master blew away QSA from the first minutes.
Much more expanded soundstage, better microdynamics, and much better bass. HF sounded more detailed and not fatigued. I’m happy that Master delivers a sweet midrange without lean sound (SR Purple does this in some components). So I need to say that Master seems to be the well-balanced fuse. No chance to QSA Violet in my setup.
The other Master I will test in the linear power supply which power my router and switch for streaming.
Also, my friend did some tests with Master in his DAC (Chord) and then in a streamer (Sonore). After a few days of tests, he is still thinking about the results.
