deHavilland Aries 572

   product Information:


The Aries 572 is a 100% pure class A single-ended triode zero negative feedback amplifier. Unlike early SET designs, the output tube of the Aries 572 is a transmitting style tube capable of very high power handling. The tube compliment combined with innovative circuitry maintains the right combination of pace, rhythm, and timing. The Aries-845 amplifier produces 40 watts, and is designed to drive medium as well as high efficiency speakers. The dynamic presentation is convincingly that of an amplifier many times greater than it's rated power output.


Historically SE amplifiers have been limited in power, largely under 15 watts. Most listeners have had to employ horn loaded speakers. The Aries 572 amplifier  will perform beautifully with your favorite loudspeakers whether they be medium efficiency dynamic or high efficiency horn type loudspeakers.


And think about reliability, with only three tubes per chassis,  diagnosing any tube problems that might occur after time is relatively simple. Quality, Value, and Performance, by deHavilland , hand built in California  with a passion for sound.
