it's me, Enzo
Hi, this is Vincenzo Grazioso’s blog about high-end audio. I’m glad to present many audio devices:

  • Power Amplifiers
  • Preamplifiers
  • DACs
  • Speakers

Usually I use vacuum tube circuit., which in my honest opinion is the best voltage amplifier: superior sound quality, highly linear without negative feedback, smooth clipping, characteristics highly independent of temperature, greatly simplifying biasing, wider dynamic range than transistors circuits, due to higher operating voltages and so on…

Please, take notice

tube circuits work with dangerously high voltages, so do not attempt to build circuits presented on this site if you do not have the required experience and skills to work with such voltages.
