Original owner. xDuoo MT-601 tube & solid-state hybrid headphone amplifier and tube buffer preamp. Headphone 1300mW output onto 32 Ohms. Many professional reviews online, and deeper dive on the xDuoo website. I upgraded the Chinese tubes to Western military grade matched 5654W. Low hours on the upgraded tube set. Replacement matched 5654W tube set is available from Amazon for $20 or so, but they should have a very long life. Free Shipping to Lower 48.

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. It isn’t subject to electromagnetic interference caused by digital components, so its total harmonic distortion and signal-to-noise ratio are exceptionally low. 53% more power than the MT-602 The MT-604 outputs up to 2000mW (32?) 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. XLR and 4.4 balanced input/output The MT-604 is a fully balanced amplifier. Plug in any source into its XLR or 4.4mm balanced inputs, and enjoy rich, unhampered sound from its XLR or 4.4mm 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. Built-in mute circuit Anyone who’s ever plugged in their headphones before turning on their amplifier knows that many amplifiers make an ear-splitting “pop!” 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.
