First unveiled in passive display at Munich High End 2024, the new D’Agostino Pendulum Integrated amplifier made its US consumer audio show debut in two places at AXPONA 2025: a hallway setup—where listening was possible only at close range—and in a room sponsored by Innuos.

The Stereophile team caught up with Dan D’Agostino during his brief visit to Chicago to get the lowdown on the newest and lowest-priced integrated in his line. Some of his remarks on sound versus measurements make this video a must-see.

The all-balanced Pendulum Integrated has one single-ended input…
