I-200

I-200

The I-200 is not just an ordinary amplifier—it embodies the concept of “pure signal amplification,” which lies at the heart of audio culture, thanks to the use of modern technologies and carefully selected materials.
The output stage uses a 6C33C triode and operates in pure Class A, in a non-feedback configuration, delivering 20 W of power.

It preserves the continuity characteristic of single-ended circuits and the natural harmonic structure typical of triodes, conveying the energy of the music without artificial emphasis or exaggeration.

Key features:

●The I-200’s uncompromising circuit design
utilizes a single-stage amplifier with direct coupling. Unnecessary components that cause distortion have been removed from the signal path, resulting in a circuit that has been simplified as much as possible. The result is a fast response and transparent reproduction of even the subtlest nuances.

● Hand-wound OCC transformers
The output transformer uses cryogenically treated OCC monocrystalline copper wire. Handcrafted by experienced artisans, it ensures exceptionally clean signal transfer.

● Precision TKD volume control
A high-end volume control from Tokyo Ko-on Denpa (TKD) is used. This remote-controlled unit ensures perfect channel balance across the entire frequency range.

● Stabilized Power Supply
Silicon carbide (SiC) components are used for rectification. Stabilization through current control minimizes noise and highlights the contrast of music emerging from silence.

● Non-magnetic, vibration-damping chassis
The stainless steel chassis, featuring a layered vibration-damping structure, reduces both external vibrations and internal resonances, preserving signal purity.

● Automatic Bias System
Automatic bias adjustment maintains the optimal operating point regardless of the passage of time or differences between tubes, combining ease of maintenance with stable performance.
