Trade-In Your PDC-2.6 and PDC-2.6P for an HDP-3!
DEQX is now shipping the HDP3 (PDC-3) Processor Preamp based on the PDC-2.6/P Rev-6 PCB that many of you already have. It’s the result of countless hours experimenting with ADCs, op-amps and DACs, the power supply and other related issues. The votes are in and the results are stunning!

We’ve achieved quantum improvements in the switching power supply and the new generation of op-amps. DEQX uses a variety of high-end op-amps based on their function. High power dual 300V/microsecond slew rate op-amps drive the AKM Analogue-to-Digital converter, and another two for each of the six DACs doing current-to-voltage conversion.

All other signal paths use new-generation very low-noise, low-distortion op-amps. Another change is the quantity and quality of bypass capacitors, while any in-line capacitors are now the new low-ESR (and very musical) capacitors.
