Combining the best attributes of several of our favorite British amplifier formats, the RSA 23 presents a truly unique and stand-alone sonic signature rarely heard before. From the speed, sensitivity and dynamics of our favorite EL84 amp from England, to the midrange punch and aggressive drive of some of our favorite 50 to 100 Watt 4-input amplifiers from England, topped off with the very unique roaring, powerful, creamy and articulate overdrive offered in our favorite 200 Watt KT88 amplifier from England, the single note chord definition at all ranges from 1 to 10 is simply spectacular.
