Zesto Audio Bia 120 Class A Stereo Power Amplifier : 

The tubes are always on, so you have power when you need it. Class A is fast and responsive. There is no lag, providing your music more punch, transient response, better dynamic range and transparency. 
The unsung hero of a power amp is its power supply. That’s why my design incorporates a custom Toroid power transformer and a choke-based, dual-mono power supply to deliver all the “slam” you can handle.

Features

  • Plenty of power to drive your speakers
  • Pure Class A power is fast and musical
  • 4, 8 & 16 Ohm taps gives you options for your speaker preference
  • Dual Mono gives you less cross talk and better stereo imaging
  • No adjustments with Auto Bias. Its safe, consistent and settings are always perfect
  • Provides enough gain for most standard preamps and accommodate most speakers
  • Choice of either Single Ended RCA or Balanced XLR to suit your needs or cable preferences
  • Transformer balanced XLR input offers true noise rejection and isolation from the preamp
  • Left and Right ground switches on the XLR balanced inputs to help eliminate ground hums
  • No Negative Feedback provides for virtually no compression to your music
  • Custom Toroid provides lower noise with plenty of available power
  • Global mains power supply can work all over the world
  • KT120 compatible
  • Push-Pull circuit design gives you more power
  • Ultra-Linear circuit design provides lower distortion
  • Low noise levels allow really dark black quiet musical passages
  • Non inverting polarity retains the same phase as the input (so your trumpets blow and don’t suck)
  • Gold pin sockets are more reliable because gold doesn’t’t oxidize when it heat cycles
  • Matched quad output tubes retain the stereo balance
  • It’s ready to enjoy with 50 hours of factory burn in on all circuits and vacuum tubes.
  • Elegantly designed, heavy duty 14 &16 gauge zinc plated steel enclosure
  • Each unit is hand built “Made in the USA”
  • The wide frequency response allows you to hear the finest passages in your music.
  • High quality gold plated RCA, XLR connectors and 5 way binding posts
  • All fuses are easily accessible
