Tube Headphone Amplifier DAC Preamplifier 12AT7-TII Bluetooth 4.0 CSR8670 XMOS ES9018 Decoder DSD Luxury Version on Flickr.
This is one of the most completed ES9018S advanced decoder in the industry currently, which can be used as HIFI headphone amplifier or preamplifier. Built-in XMOS (U8) + ES9018S + Bluetooth CSR BC8670, all functions are currently the best configuration. With the highest level decoding solution at one time, it built in USB digital interface XMOS (U8) program to support DSD hardware decoding, also it adopted HIFI tube-transistor hybrid differential amplifier circuit for headphone with strong driving force and Bluetooth CSR BC8670 programs to support high-quality lossless transmission APTX (I2S input receiving a digital signal after ESS9018 decoding preamp output), at the same time it supports OTG input function from the smartphone. Used a unique Patent tube-transistor hybrid differential technology as discrete components core made, it achieve high-quality pre-amplifier output also. The sound features of the preamplifier and headphone output is warm, delicate, transparent, fast, wide sound field and very dense. If your amplifier is insufficient driving force or its sound is chilled, you can use it to drive your headphones and earbuds or use it as a preamplifier; its sound quality will have significant improvement that can fully make your equipment sound achieve another higher level. Its unique patented technology for the core tube-transistor differential amplifier with full hybrid discrete components and parts designing, includes tube differential amplifier, preamplifier, driving amplification, power amplification and feedback tube recycling, combines the properties of transistors and tubes, so that it gets more delicate and gorgeous sound, and get transistor sound effect with rich transient, thickness, density of the sound quality, and higher driving force, which cannot achieve the sound quality and height if only depend on tube or transistor circuit designing.
