It looks unique and elegant. Dual and mono channels separated. The similar typical vacuum tube audio is sold with price among USD2,000.00 to USD3,000.00 in the market. This M30 is merging designed with preamp. and poweramp. The front two vacuum tubes are preamp, the latter two higher vacuum tubes are poweramp. This appearance follows a new fashion trend in the modern vacuum tube audio design. 2, Materials All materials of M30 vacuum tube audio are processed by HI-FI class of standard. The materials are meticulously selected among hundreds of choices. 1) The casing of amplifier is fully aluminum and is processed meticulously by oxidation. Such a big investment is different from the common vacuum tube audio. M30 should be an innovation for HI-FI vacuum tube audios. 2) The voltage is amplified by preamp 6N8P which is produced in China. It is amplified from backward. The poweramp works with vacuum tubes EL34 which is produced in Russia. 3) The casing of M30 is fully aluminum. And it has been oxidated to be an aluminum plate surface color. It looks smooth and very luxury. It is processed as the other expensive audio which cost more than USD1,500.00 in the market. It has the effect of brand audio. 4) To ensure the accuracy of the whole system, all spare parts are processed by CNC maching. Wiredrawing and sand blasting treatment is used in order to ensure the completeness and accuracy. 5)The vacuum tube cover to protect components is an individual part. Thecoveris processed with knurling press and sand blasting treatment. It looks fashion and elegant. There are a round cover and a square cover to protect the back transformer. M30’s appearance shows your unique personality. 6) The transformer of M30 is one of the very important components in the whole system. The sound’s quality depends on the transformer’s quality. All transformers are imported from Japan which are processed by silicon steel. The music style of this product is depends on this audio output transformer. M30 have good performance for low frequency, intermediate frequency and high frequency with powerful and clear sounds. We worked a lot for designing the output transformer in order to meet most people’s sense of hearing and have more fans for our M30 vacuum tube audio. 3, Timbre M30 vacuum tube audio is a very comprehensive vacuum tube sound system. It doesn’t have sweet and strong sound like other tube amplifier, because it will be destroyed on dynamic. M30 system seeks to reproduce the real music, it fully explores the tube potential of ease, natural and clear. You can easily identify the tube sound. At the same time, it has sufficient dynamic and plays music with passion and lively.
