AD-2500 selects eight pairs of high-power famous tubes of ON Semiconductor NJW0281G/NJW0302G paired with high precision. The performance of the tube is quite stable when the working current changes in a large range, and it will not affect the sound quality and timbre.

The tube has excellent listening performance in the whole frequency range, with delicate texture and oily texture, full timbre, transparent and strong resolution; it will neither appear dull in low frequency nor feel frizzy in high frequency, and has strong plasticity, which is Not only is it a style favored by sound designers and tuners, but it is also a good sound pursued by the majority of audiophiles.

The whole machine adopts HI-FI design and structure technology, the panel is inlaid with black aluminum alloy and elegant and restrained acrylic plate, and the inner lining is eye-catching lake blue mechanical pointer type voltmeter.
