Pure Class A Amplification

The EA13 draws inspiration from the legendary tube amplifier circuits of the 1950s, reimagining their timeless design with modern engineering.

Its pure Class A push-pull architecture, combined with EL34 output tubes operating in pentode mode, effectively minimizes distortion while delivering a sound signature that is:

• Transparent

• Richly detailed

• Natural

• Smooth and full-bodied

With an output of 28W per channel into 8Ω, the EA13 is capable of driving most bookshelf speakers as well as many floor-standing loudspeakers with ease.

Carefully Selected Vacuum Tubes

The EA13 comes equipped with six premium imported vacuum tubes.

Preamplifier Stage

2 × Sylvania NOS PCF80

Vintage New Old Stock American tubes used in the voltage amplification stage, delivering an open, transparent, and natural sound.

Power Amplification Stage

4 × JJ Electronic EL34

Premium Czech-made EL34 tubes renowned for their classic tube sound, offering:

• Warm tonality

• Full-bodied presentation

• Rich harmonic character

Note

Due to manufacturing batches, storage conditions, and the natural oxidation process, the printed markings on the vacuum tubes may show slight fading, discoloration, or partial wear. This is entirely normal and does not affect performance or sound quality.

Premium Construction

The EA13 combines modern aesthetics with a robust chassis engineered to minimize vibration and electromagnetic interference.

Construction highlights include:

• CNC-machined aerospace-grade aluminum front panel

• Sandblasted finish

• Unibody chassis

• Excellent electromagnetic shielding

• Recessed tube mounting

• Integrated protective tube cover

• Side ventilation grilles

• Vibration-damping feet

Precision Volume Control

Volume adjustment is handled by a 40-step precision analog stepped attenuator featuring:

• 40 discrete volume levels

• Precision-matched resistors at every step

• Excellent left/right channel balance

• Greater long-term reliability than traditional carbon-film potentiometers

• Highly accurate volume adjustment

Dual Mechanical VU Meters

The EA13 features a pair of genuine mechanical stereo VU meters with warm LED backlighting.

Features include:

• Vintage-style LED illumination

• Dedicated VU meter control circuitry

• Real-time needle movement synchronized with the music

Note

The VU meter needles may exhibit a deviation of up to ±1 mm from the zero position. Slight left/right needle misalignment when returning to zero is a normal manufacturing tolerance and does not indicate a defect.

Audiophile-Grade Components

The EA13 incorporates carefully selected components to maximize sonic performance.

Coupling Capacitors

High-quality axial metal film coupling capacitors provide:

• Low signal loss

• Reduced distortion

• Excellent long-term stability

Power Supply Capacitors

Large-capacity Japanese NCC electrolytic capacitors ensure:

• Clean power delivery

• High energy reserves

• Improved tube sound performance
