After long months with Stax "Pluto 2A3/SE" amplifier, I was looking to use it as a driver amplifier for "something bigger...

Triode-like behaviour of bottom SiC MOSFET endstage. Topside MOSFET - gyrator and output. CREE SiC 1700V ( C2M1000170D ). First tests are...

Got a idea about preamp, which was based on parafeed µ-metal transformers. Here you see endstage wired as triode, driving output transforme...

Since I am very satisfied with 12AX7 gain stage supported by MOSFET, I was curious how to reuse this design elsewhere. Here it is, a pu...

Let me show few more examples, how to put this system on even higher sound quality level.  Warning, additional expenses ahead. I´v...

After a many positive STAX reviews I decided to try them out. Wish i got this idea much sooner!   Soundwise nothing compares to micro det...
