20Wrms / channel All-in-one
(pre-amp / power amp / integrated amp / headphone amp)

This is one of our newest state-of-the-art designs, which is truly a multi-purpose fit for almost every application. This unit is composed of a pure tube pre-amplifier circuit of 6SL7x3 , with a built-in HPF input (high pass filter) and a solid-state 20Wrms non-negative feedback buffer amplifier, which can serve the following different configurations:

1. Pure class A single-ended tube pre-amplifier use 6SL7 x 3 ( alt: 6SN7/6SU7/6188/ECC32/ECC33/ECC35)

2. 20W/ch Class A hybrid power amplifier with 4-16 ohm driving capability

3. 20W/ch Class A hybrid high frequency band power amplifier for easy bi-amping (300Hz - 150Khz)

4. 20W/ch Class A hybrid headphone amplifier which can drive headphone with any sensitivity

5. 20W/ch Class A line level input integrated hybrid amplifier

6. Connect another power amplifier to form a bi-amping system

When using the HPF input mode, this amplifier can give the same loudness and dynamic level same as a 100Wrms power amplifier.
