100Wrms x 2ch high current single-ended tube hybrid integrated amplifier

This is one of our new state-of-the-art 2016 design hybrid integrated amplifiers that combines both the advantage of high power class AB MOSFET amp's high current drive capababilities (tight bass and good speaker control) with single-ended vacuum tube pure class A amplification (warm and sweet sound with excellent depth, wide open and airy sound stage).

The conventional output transformer of conventional single-ended tube amplifier was replaced with a super high current, high damping factor MOSFET transformer, which can output 100W continuous power per channel at 8 ohm loading , this amplifier can drive down to 4 ohm without problem, or even 2 ohm speaker with reasonable loudness. Built-in over-temperature and over-current protection for safety operation even under extreme condition. The tube section is working in pure class A single-ended operation in order to achieve the purest and most natural ORGANIC sound.

This integrated amplifier has a very flexible tube rolling capabilities, pre-amplifier tubes are 6SL7x2 + 6L6Gx2, the 6SL7 tubes can replaced with 6SU7, ECC32, ECC33 and ECC35 or equivalent models, the 6L6G tube can use tons of different power tubes like 6550, EL34, 6L6, 6V6, 6F6, 6K6, 5881, 6CA7, KT66,KT77,KT88...etc. With this super high tube rolling flexibility, you can make this amp match whatever other components without problem.

This integrated amplifier comes with 3 sets of inputs for flexible connectivity. Pre-amp output available to hook up other power amplifiers or working as bi-amp or even tri-amp setup.

Convenient headphone output included for any headphone connection. Default wiring is parallel run with speaker output, this option can give best sonic performance but you will need to disconnect speaker wire during headphone listening session. Optional wiring can wire as the same as all others manufacturers, when headphone plug in the speaker output will be disabled, but this option will need to pass through an extra set of switching circuit and sound quality might be compromised.

If you judged the sound quality by listening, you would believe this is a pure tube single-ended high power amplifier which worth over $10K in the industry.

Regulated version has one of the following of your choice:

option A: 500W regulated power supply upgrade

The sound stage will be even more 3D holographic with better dynamics, details and focus, the bass extension down to the very extreme with excellent control and punch. The sound stage and integraty can still hold even with big bang orchestra or hard rock/heavy metal playing in high loudness level.

option B: MDE micro-dynamics extraction up-grade

The sound stage will be even more 3D holographic with extremely good micro-dynamics, details and focus. Those music covered by background noise surface out effortlessly, you can hear those faint passage which you never been able to aware before. Vocal is so real and touching with emotional eruption, musical instrument regenerate like a real live performance simulation.
