Review: Audio Research Corporation HD 220 Amplifier


Category: Amplifiers

My musical tastes include primarily classical, jazz, folk/blues and some exceptional rock. Specific recordings can be discussed via phone @ 610-721-1304. Soundstaging, dynamics, transparency and coherence are paramount, while the correct tonality and warmth are of equal concern. In other words I need it all to be right or else I sell the stuff! My HD 220 has 300 hours on it at this point and it is exceptional indeed. My recent decent into Krell evo solid state gear left me wanting so I sold the rig and started anew.

When a system is in the "zone" for me it conveys lifelike dynamics, accurate tone, clarity with warmth and soundstaging to die for!! This amp does it like no other I've had on all types of music (taken as part of my current setup). One major note...USE THE STOCK POWER CORD!!! The HD 220 started to amaze me aftethunderousr I decided to try it's own power cord in place of my reference cords. As long as my ref 3 has a great power cord all is well. The amp conveys a sense of limitless power with explosive yet controlled dynamics...it is effortless but with great force and dynamic swing!! Treble is extended and full of sparkle but grainless and pure at the same time. Midrange is full and neutral with a tad of warmth, but not overdone. Bass is earth shaking and well defined with amazing definition. Focus and placement of instruments is the best I've heard. Width and depth of the soundstage is top notch as well. Palpability and presence are eerie baby...spooksville!!

Compared to the other great tube amps past and present it connects on excitement, dimensionality, dynamics and extension without the tube haze, lethargy and softness often found with their presentation. I prefer it over the 110 for real world reasons and for purely musical ones. Overall it takes one away with the music where very few other components take you!!

Money is no object for me ...the HD 220 is staying..it's that good!!

Thanks for the review. It's very difficult to find any information on the sonics of this new Hybrid amp from ARC. It looks like I'll be buying an HD220 too, as soon as I get back to the States from Mexico. It'll be nice to have a good sounding ARC amp with only 4 tubes and no manual biasing. Esharp
I also had an ARC 150.2 and loved the ergonomics but couldn't make friends with the treble. I am currently running a 100.2 which continues to satisfy but it does run a bit warm. If anyone has been able to listen to both the 100.2 and the HD220 I hope they will post a comparison of the sound and the heat output.
