Features: Using pre-bile after the stone design, the former two Beijing Dawning factory produced 6N3, sound moderation, but just to improve the V5 small size full-frequency unit high-frequency too bright problem. While the Philips TDA1517 is responsible for post-class, the combination of the A1 with a rounded sweet voice, with the V5 speaker is particularly suitable for playing female and string. And V5 is the use of acid wood stickers, not only antique, but also effectively eliminate the...

Features: A-6 is the biggest QINPU mini amplifier in terms of size. In order to get enough power, it became bigger and bigger in the process of design. Its panzer-like weight and amor makes it unmatched reliability. In addition to the usage of previous pre-tube design, which features QINPU mini amplifiers, A-6 adopts 3 pairs of Sanken 2SC3519/2SA1386 transistor pair. They are unique transistors with particularly warm tone color. Amplifying circuit was designed as high-efficiency class AB...
