Synergy and Insight+ Upgrades

We continue to support the Dynaco and Hafler chassis, we have since we started 50 years ago, and we don't plan to stop. We have decades of experience working with the Dyna and Hafler pieces, and continue to offer our latest products in Dyna and Hafler chassis.

We currently have the following upgrades for Dyna and Hafler chassis equipment available:

  • Insight amp upgrades and double-die MOSFET upgrades for all earlier AVA solid state circuits in Hafler or Dyna chassis. New or upgraded audio circuit boards and power supply, as required.
  • Synergy amp upgrades and double-die MOSFET upgrades for all earlier AVA solid state circuits in a Dyna 150 chassis. New or upgraded audio circuit boards and power supply, as required.

With rebuilds*, most problems with your equipment will be taken care of at no extra charge since most original circuits and their defects will simply be discarded — but please make sure you write a detailed note describing the problems so we are sure to find them. Severe mechanical problems can be resolved but may result in an extra cost billing to you. We must have working transformers, working switch assemblies, and completely assembled units with all hardware.

*Our upgrade prices assume you are sending a correctly wired and working unit not subsequently modified by others.
