The MT-601 has a good reputation as a compact hybrid amp with a bit of tube flavor, and A$128 looks a touch high against its usual new-ish street pricing and the kind of used value this model tends to hold. With the amp commonly sold around A$89 new and seen used more in the roughly A$65–A$95 band, this listing lands above fair-buy territory unless the condition and extras are especially strong.
That said, it’s still a worthwhile little desktop amp if you want an easy, forgiving sound and a simple RCA-front-end for efficient headphones or IEMs. The upside here is more about the character than brute power: it’s a tidy way to add some warmth and presentation without spending much. I’d want clear photos, the original power supply, and confirmation it’s functioning quietly; at A$128, those details matter more than usual.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
xDuoo is a Shenzhen, China-based audio brand that emerged from the country’s fast-growing hi-fi manufacturing ecosystem. Its exact founding year is not consistently stated in the sources available here, and no founder is prominently verified, but the company is widely presented as Shenzhen xDuoo Technology Co., Ltd., with roots in OEM/ODM production before building its own consumer-facing identity.
The brand is best known for headphone amplifiers, DAC/amp combos, portable DACs, tube hybrids, and other desktop-and-portable electronics aimed at personal audio enthusiasts. xDuoo’s lineup has included tube headphone amps, balanced amplifier designs, digital-to-analog converters, and all-in-one sources, typically positioned for headphones rather than loudspeakers or turntables.
In the market, xDuoo sits in the value-to-mid-tier audiophile segment, with a reputation for offering ambitious feature sets, lots of connectivity, and occasional tube-flavored designs at relatively accessible prices. It is not generally considered a luxury or vintage-collector brand, but rather a practical, performance-driven Chinese hi-fi maker with a strong presence among enthusiasts seeking high features per dollar.
