extension and drive of high-power transistor amplifiers without the muscle- bound sound, and the elegance, emotion and tonal colors of flea-powered single-ended triode vacuum tube amplifiers without being weak or flaccid.

The origins of the DPDS comes from the principles of tube amplifier design – some of the qualities of tube amplifiers were as much to do with power supply design as the choice of tubes over transistors. Because of the high voltages involved, tube amplifiers use relatively small capacitors and chokes to produce smooth DC power.

Transistor amps use cheaper, larger, and lower-voltage electrolytic capacitors to do much the same job. From this we discover a very simple fact, smaller capacitors usually sound better. This is not only speculation, there is good science to predict that the high frequency performance of large capacitors to be poor.

There are lots of very small solid-state amplifiers that have excellent sound. They all had tiny power supplies, and the smaller the power supply, the “faster” they sounded. On the other hand, very large power amplifiers with huge capacitors, or even large banks of smaller capacitors in their power supplies tended to sound dark and slow.

The DPDS in the simplest explanation uses the frequency distribution of music, and the Fletcher Munson curves to predict the required power delivery to play back music. Then, it uses a Class D amplifier module as a “perfect music-driven faucet” to deliver current to the connected loudspeakers.

This is the issue of speed vs power. The sprinter is not able to sustain the delivery of power for very long, but the marathon runner is not able to deliver very quick bursts of speed. The DPDS is like a relay team with sprinters, medium-distance, and long distance runners in the team. Thus, it is able to deliver high power, as well as very quick bursts of speed.

Such a “relay team” is what gives the Genesis Reference Amplifier the excellent micro-dynamics, tonal contrasts and timbre textures of low- powered amplifiers, and yet is able to deliver huge dynamics and the sustained deep bass of muscle amps.

The optional Maximum Dynamic Headroom Reservoir extends this ability down to loudspeaker impedances of 1 ohm and below by extending the relay team, and adds proprietary resonance control circuitry to ensure that the “baton handover” from one team member to the next is handled as smoothly as possible. This results in increased dynamics from having more current
