Stax, which is dedicated to the production of electrostatic headphones, recently launched its flagship ear amplifier SRM-T8000, which uses a front tube and rear crystal design. The first stage of amplification uses two 6922 dual triodes, an independent circuit board, and the vacuum tube is also shock-proof Processing, this design is to avoid vibration interference. In the output stage, it is a crystal amplifier, and it works in a class A mode to achieve lower distortion. The amplifier circuit is fully balanced to reduce noise and provide a more powerful output. A large toroidal transformer is used internally, all parts are matched and selected, and the quality is excellent. In addition, SRM-T8000 can also bypass, skip the volume control, users can use other equipment to control the volume, let SRM-T8000 be used as the rear stage of the ear amplifier to drive the earphones. This is a rare feature in ear expansion.
This unit has 2 groups of RCA unbalanced inputs, 1 group of XLR balanced inputs, and two groups of electrostatic earphone outputs, which are exclusive ear amplifiers for Stax earphones. The maximum output voltage can reach 470V RMS
