Audiophile speakers like electrostats and difficult to drive low impedance towers perform best with ultra-clean high power amps that can handle low impedance loads. If you’ve been dreaming about hearing the uncompressed dynamic range of live concerts on Blu-ray and Hi Res Audio downloads of studio master recordings, you’re going to need more power to take you there. Remember, to hear clean un-clipped sound 3 dB louder than the amp you have now, you’ll need to double your current power output.
Now is the time increase your systems output power with the 90% efficient Essence DPA-440 Class D Digital Power Amp. Better sound, better economics, and an eco-friendly design for modern thinking people.

Clean Class D Power For Hi Res Audio 

Why are Class A and AB amps so expensive? The simple truth is, they convert electricity into watts less efficiently.  The lower the efficiency, the more heat the amp produces.  The chart below vividly explains; Class A amps are 20% efficient, Class AB amps are 50% efficient.  Both designs create more heat than power to drive your speakers.  Since heat is the enemy of solid state devices, these amps must employ ways to get rid of it. 

Audiophiles hate fans because they are noisy so manufacturers of Class A and AB amps are forced to use a lot of heat sink surface area to  pull the heat away from the amp.  The surface area requirement leads to a huge chassis to house the heat sinks and transformer. The cost of the materials to make the chassis to house all this heat sink is by far the biggest factor in why these amps cost so much today, its the packaging, not the transistors or circuit boards.  

Class D amps are 90% efficient so they dont need as much heat sink or the big chassis to house them, leading to lower costs for consumers per watt.  Further, Class D amps now sound better than the old fashioned Class A and AB amps we grew up with, they have lower distortion and noise and handle difficult loads better, with more slam and an ease of operation as they produce prodigious output for a lot less money.

Hi Res Audio brings us all the emotion of a live performance at home as never before with uncompressed 24/96-192K Blu-ray Concerts, Pure Audio Discs, SACD/DVD-A, and Hi Res Downloads for the most unveiled sound and transparency in audio history. Class D is swiftly taking over the audiophile market, the only people still complaining about how they sound are the manufacturers who still make the Class A vacuum tube and Class AB solid state amps from the last century.  In a world getting hotter by the year, its really past the time to indulge in fantasies and rationalizations about which type of amp class sounds best.


With Class D you get 66% more output power for 1/3rd the price and lower your audio system’s power consumption by more than 50%, lowering your electricity bill as well.  In the chart below, note that the Class A amps use up the most electricity because they are on at full output all the time, yet 80% of that electricity is thrown away as heat.  

That leads us to the Essence™ DPA-440 Class D Digital Audio Power Amp. It’s easy to find amps that can excel in one or two parameters but the DPA-440 is an amp that does everything well. With its wide open-loop bandwidth, extremely low-phase shift, almost non-existent noise, harmonic and intermodulation distortion independent of load, high current capability, low output impedance uniformly at all audible frequencies-it all adds up to incredible performance.

Modern Digital Amplification

The Essence DPA-440 uses the latest Class D topology to provide a highly efficient and nearly ideal amplifier with distortion below measurement, ultra-high damping factor, and unconditional stability with any speaker. Tight, detailed sound with amazing control and transparency delivers the best performance available.
The all-discrete driver and output stage have lower open-loop THD as well as lower idling losses, normally conflicting requirements with conventional IC driver circuitry.This is added to the DPA-440’s already amazing characteristics of load invariance and high current capability, common characteristics of great-sounding amplifiers.

Effortless Power

By using the latest generation parts and thinking, the DPA-440 offers a minimum of 220W per channel @ 4 Ohms (Essence™ Electrostatic speakers are 4 ohm) with amazing reserves of dynamic power at lower impedances. The DPA-440 is capable of up to 400 watts dynamic power per channel @ 2 ohms. It can effortlessly power any loudspeaker to live performance levels with amazing efficiency and low power consumption.

Clean and Dynamic

The performance of the entire signal path is critically dependent on the power supply; in this case a well regulated switch mode design with 90% efficiency. This allows maximum dynamic power, very high current yet with very low distortion. Secondary supplies are individually regulated and decoupled at each op amp for lowest possible noise and maximum dynamic range. The DPA-440 is protected against thermal overload and against being over-driven, which is almost impossible.

When combined with the Essence HDACC Upsampling DAC Preamp, the system performance reaches the highest level of clarity and resolution attainable today, at a price that’s sure to make heads spin. The amp is our latest disruptive innovation.

Outstanding Testimonials for the DPA-440: 

Thierry Langer, Maryland Oct 2015 – October 2, 2015 

I totally agree with John Gatski.

After 50 hours of listening, the
amp sounds now exactly as if it would not being there. Not the enormous ,
“hugeissime “ sound of my late Jadis, but just a reliable tool for 1/8th of the
cost. More details, more credible image, just more demanding on the quality of
the records I play.. Thank you Bob   Thierry Langer, Maryland Oct 2015

George Deane, NY July 2015 – July 23, 2015

Yes Bob. Received it on Tuesday,
hooked it to the speakers and consider the result superb.  I can’t ask for anything more, except cd’s
that can meet the standard of the speaker. 
Your insight and wisdom on audio matters are much appreciated. It’s only
rarely that I have met someone in the audio world that can match your knowledge
of audio. So thanks for everything! George Deane, NY July 2015

Enrique Diaz Guzman – May 18, 2015

I truly consider that your work
and knowledge with the DPA-440 was well worth it, I don’t know the amount of
collaboration between Tom and you, but you two are a couple of geniuses. These
two products, the HDACC and DPA-440, are completely amazing in sound and they
really will go toe to toe with some tubes I've heard and you’re totally right
they (the tube amps) should be modern day heaters instead of amps. You
certainly are a league on your own, this system that you designed is certainly
top of the line…In short THANK YOU for the sound in my room, you leave me
responsible for selling my older amp and preamp that I will never connect
again.” Enrique Diaz Guzman, Mexico City, [email protected]
