●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.
