Euphonic Audio iAMP

While most manufacturers of Class D amps keep their products’ weight and cost at a minimum by employing a switching power supply, the designers at Euphonic Audio believe that a conventional linear power supply with a toroidal power transformer yields better sound-a smoother, fuller tone without brittle midrange. To wit, in the realm of high-fidelity instrument amplification, Euphonic Audio stands out from the rest of the pack. The company’s pursuit for perfect tone that has led it to create what may well be the best-sounding Class D amps on the market, if not the most lightweight.

Bassists are the target market for EA’s iAMP-200 head unit, but I was pleasantly surprised to hear how great my archtop guitar sounded through it. The 200 can be paired with any speaker cabinet, including EA’s own WZ112 Wizzy or WZ112P powered cabinet, by way of a link output. Both of those four-ohm cabinets get the full 200 watts from the iAMP-200. Plugging the iAMP-200 into my eight-ohm cabinet yielded 165 watts, more than enough for most jazz guitarists. If headroom is an issue, EA also offers the iAMP-500 and iAMP-800, which are slightly heavier but plenty powerful. The iAMP heads range from eight-and-a-half to 19 pounds, and each occupies three spaces in a rack setup to insure proper ventilation. Guitarists would want to add a reverb unit to the rack and then pair it with a small cabinet, making a great-sounding portable amp.
