We’re happy to announce we now have upgraded amplifier circuits for our original D series amplifiers.
These models were built in the early 2000’s and were one of the 1st reference quality class D audio amplifiers.
The new circuit produces 100 watts into 8 ohms and 200 into 4, with even lower THD/IMD, better efficiency, and user selectable gain (26dB/32dB) for use with both passive and active sources.
Upgrade cost is $600 per pair and comes with 1 year warranty.
