Yes it does accept banana plugs. Below is a picture of the back of the unit:
I have seen several photos of the amp's back side online and saw the Cardas binding posts with holes in them. But I was not sure.
Also, I have obtained a PDF copy of the owners manual for the DNA-1. The manual does not state "Deluxe". Is this manual for both the standard and Deluxe versions?
There is no functional difference between the standard and deluxe models, so the one manual covers both.
The Deluxe upgrade program originated with the DNA-1 amplifier around 1993. It consisted of replacing a selected set of parts with higher-performance, more expensive parts for improved performance. In the case of the DNA-1, the RCA jacks and speaker terminals were upgraded to Cardas, and several critical resistors were upgraded to Vishay and Caddock. The regulated power supply rectifier diodes were replaced with soft-recovery units from Harris, and the output wiring was upgraded to Van den Hul. These changes resulted in a nice performance enhancement at a very reasonable cost. The Deluxe upgrade program proved to be so popular that we extended it to include most of the products produced at McCormack Audio.
I finally acquired a DNA-1 Deluxe through Audiogon. Hooked it up to my TLC-1, DAC-1, and SST-1 transport. The DNA-1 is larger in life than in the photos. It weighs a ton too.
Alternating between B&W 803S and Energy Veritas V2.4 speakers using bi-wired MIT Terminator 2 banana connections, I have never heard these speakers play so good. I am very pleased with the results. I have no regrets getting the DNA-1 Deluxe.
