xDuoo MT-601S Headphone Amplifier

The xDuoo MT-601S Headphone Amplifier pairs a couple of circuits to deliver well-rounded, well-outfitted desktop headphone amplification for a variety of setups. Armed with a 12AU7 tube in the preamp circuit, this headphone amp provides warmth and sweetness on the source audio coming in. It also features a traditional transistor circuit to give you access to the best of both amplification worlds, simultaneously. The MT-601S comes in a classy sand-blasted aluminum alloy shell in a subtle gray color that leaves a cutout for the tube to add a bit of extra organic flair. There’s a RUBYCON capacitance filter capable of providing smooth, even volume adjustments throughout the range, and because there’s both an auxiliary RCA output suitable for preamp use cases and a front-mounted headphone jack with plenty of headroom—you’ll have all your audiophile angles covered.
