At first glance, the 91E feels solid and purposeful. Everything fits together with impressive precision, and it is clear this was built with great care. The layout is balanced, which makes it feel calm and composed rather than overly technical.
The front panel is beautifully laid out, with a large volume knob on the right, tasteful buttons on the left and color display in the middle. The star of the show, though, is the pair of 300B vacuum tubes. They are visible through a carefully designed top panel, and while they definitely catch the eye, they do so with quiet elegance rather than showmanship.
The amplifier has a strong presence without feeling overdone; with clean lines and materials chosen for both function and beauty. This isn’t just an amplifier, it is a brilliantly crafted object that blends classic inspiration with modern design.
Class A, single-ended integrated amplifier.
Available in Nickel, Champagne and Black.
