HiFi News Group Test Winner – April 2014 edition.
“… one of the most capable and high performing 300B-based amps we’ve tested in HiFi News.” – Paul Miller
The CS300 Tube Integrated Amplifier uses the gorgeous 300B for single-ended Full Class A Amplification. The direct-heating dynatron has very small internal resistance and a very stable emission efficiency in the cathode. With quite excellent amplification performance, high fidelity, and ultra low distortion, the audio signal is reproduced exceptionally well and the voice is clear, transparent, exquisite, mellow, warm and melting.
The 12AX7 is adopted and forms part of the standard amplification circuit in input stage, while the driving end adopts the 6SN7GT/G combined tube coupled directly with the power amplification transformer to match the impedance resistance and separation segregation of the levels. This circuit design also adopts Xindak patented technology to make the driving circuit perfect. In the amplification level the direct-heating tube 300B was adopted, and the advanced EI 50/3.5k output transformer, stabilizes the fixed grid negative voltage.
Two pieces of military-level annulus power transformers were adopted for filament negative voltage and for Hi voltage separately. The 5U4G tube is adopted for commutation. Besides, the CLC ruby capacitor filter, Amplifier tube grid negative voltage, specific manostat were adopted to enhance the stability of this device.
