The circuitry technology concepts developed by MBL, such as the "DPP" (Direct Push-Pull) and "IGC" (Isolated Gain Cell), are combined here with a unique new circuit board design with ultra-short signal paths. In addition, special low-induction MBL components in the passive environment make it possible to exploit the full bandwidth of this amplifier.
  • Multi-layer PCB with heavy CU planes in the output section
  • Gold-plated copper planes
  • Layout in "ground-plane" and "eye-of-an-needle" techniques
  • Low-induction MPC resistors and MHz-type RSH capacitors
  • Super-fast ring-emitter transistors in X-crossed array
  • Regulated power supply for the Class-A drive electronics
  • Custom MBL-built binding posts made of pure copper
  • No output relays
  • 198.000 uF custom-built "long life" power capacitor bank
  • Pure copper internal wiring 6NCU
  • DC servo coupling
  • Flat frequency response to beyond 350 kHz
  • Outstanding mechanical structure, in a compact housing

...and a few secrets that we would rather keep to ourselves.

This fully balanced differential amplifier employs 2 custom-built toroidal transformers for the power stage and 1 custom-built, fully shielded transformer for the driver stage. All mbl transformers are mounted on a metal shield and encased in epoxy for ultra-effective damping. The output stage and the driver stage employ separate supplies to fully isolate the output stage from the input stage.

As far as the sound is concerned, this is the weapon to protect the beauty of the music from all deleterious influences. This is the amplifier you have always been seeking for.

Just open your ears and listen.
