xDuoo MT-604 Balanced Tube Headphone Amplifier

Fully-balanced tube amp xDuoo doesn’t do incremental improvements. They evolve by leaps and bounds.

The MT-604 is a Class-A tube amp that doubles its predecessor’s tube count and channels, making for a fully balanced tube amp experience. Class-A amplifier The MT-604 is a class-A amplifier.

Using simple circuits that draw the same amount of current and consume the same amount of energy whether receiving a signal or not, this is the most straightforward of amplifier types. 53% more power than the MT-602 The MT-604 outputs up to 2000mW (32Ω) of power.

That’s 53% more power than the MT-602--enough to drive even the HiFiMAN HE-4. Tube + transistor A common complaint about tube amplifiers is their lack of high frequency response and resolving power.

To overcome this, xDuoo added a rear transistor circuit capable of large dynamics, high speed, and resolving power. Tubes + transistor: the best of both worlds.

4 balanced input/output The MT-604 is a fully balanced amplifier. 4mm balanced outs.

Independent left/right volume adjustment Sound bias--the phenomenon of one driver being louder than the other--is a thing of the past with the MT-604. Independent left and right volume adjustments let you control each channel separately, ensuring perfectly equal volume across both headphone earcups.

” noise when turned on. Thanks to a built-in mute circuit, the MT-604 prevents this from happening, saving your ears and your patience.

Interference-blocking chassis with sand-blasted texture The aluminum alloy chassis offers a rugged defense against bumps, bruises, and electronic interference. The sand-blasted gray shell beautifully complements the striking red dials and atomic-era aesthetic of the tubes.

Tubes will roll Adventurous audiophiles will love swapping out the stock tubes for other tubes. Every model of tube has a different sound signature, enhancing or reducing warmth, detail, and soundstage.

It’s a fun way to play with the sound signature of a single amp, often for less than $30 a pop. Just be sure to find a reputable dealer of tubes before buying.
