Classic tube power meets modern technology in aerospace engineer Roger Gibboni’s designs—there’s a free iOS app enabling control of volume, source switching, and operating mode (Ultralinear or triode). Although intended as an entry-level offering, this integrated is definitely not a watered-down version of one of Rogers’ big push-pull amps. In fact, it’s something totally different—a single-ended design using one EL34 power pentode per channel (upon request the amp can be shipped with a KT88 beam power tube). Reviewer DO says you really would be hard-pressed to find a more cogent and emotion-packed midrange. (283)
