Our verdict

A decoder amplifier for someone who wants USB and Bluetooth 5.4 input, a tube-and-transistor design and a stated 1500mW at $237.15. Look elsewhere if you need a named DAC chip, a headphone port list or a load behind the power figure, since the listing text gives none of them. The main caveat is that the page's sound and latency statements are the maker's own claims.

You need the page to name a DAC chip, list the headphone ports or give a load for 1500mW.

Tube amplification paired with transistor buffering is how the page describes the xDuoo DM-01, a decoder amplifier whose body is a single CNC-machined aluminum block. It lists up to 1500mW of output power for headphones from 16 to 600 ohms, an XMOS 16-core XU316 chip, and support for PCM 32Bit/384kHz, DSD256 and MQA 8X. A Qualcomm chip is listed for Bluetooth 5.4. It is priced at $237.15 as one orderable option.

Options and pricing

There is a single orderable option at $237.15, so there is no color, plug or bundle to choose between. Beside the price the page shows $279 crossed out, which is the store's own comparison and not something we checked. The listing text does not say what comes in the box, so the contents are unknown from the page text alone.

How it compares

The xDuoo TA-66 is listed at $212.49 and the TOPPING Mini 500 at $229, both under the DM-01's $237.15. The SMSL AO300 PRO costs $245.52 and its listing text mentions the CS43131 chip, whereas the DM-01 listing text gives no DAC chip. The names and spec lines of the first two carry no figures to set beside the DM-01's 1500mW.

Shipping

  • Methods and costs. The store's shipping page offers Standard Shipping (4PX, Yanwen or Yun Express), free for most countries, and Express Shipping (DHL Express, FedEx or SF Express) at 15-50 USD depending on the country, free for orders over 270 USD in most countries (checked 2026-11-11).
  • Large items. The page says headphones and desktop DAC/AMPs count as large items, for which Express is free only for orders over $499.99.
  • Delivery times. It says an in-stock order ships within 3 working days, Standard takes about 2 weeks after shipping out (up to 1-3 months for some countries, and the store makes no refund for that transit time) and Express takes about 3-7 days. Festive seasons and other circumstances can change the timing.
  • Taxes and fees. The buyer pays any customs, import or processing fees. The page says Standard via YunExpress is tax-inclusive for some countries, that remote areas can carry extra Express charges, and that a parcel refused or left uncollected over taxes is deducted two-way freight and may be destroyed with no refund.
  • Where it ships. The page says the store can generally ship to most countries by Express and many by Standard, and to confirm Standard with the team for your country. It cannot ship to PO boxes or APO/FPO addresses and can only use Express to Hawaii. It does not name the US, Canada, the UK, Australia or New Zealand, so confirm before you pay.
  • Lost parcels. If a parcel has been in transit for at least 3 months, the page offers a one-time reshipment or a full refund for orders under $50 and a 50% refund for orders above $50.

Returns and warranty

  • Returns. The return page allows returning any non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying the shipping. Email [email protected] within that period; the store asks for the return to be shipped within 5 working days of the RMA instructions and in most cases processes a refund within 5 business days of inspecting it (checked 2026-11-11).
  • Opened items. A product opened within the first 7 days after delivery can be returned for the price minus a restocking fee of 35% of its retail value, including when it still works properly.
  • Refund or credit. The buyer can choose a refund to the original payment method (PayPal or card) or store credit; with no answer within 48 hours of confirmation the default is store credit, which can also be prioritized during promotions, final-sale events and for items 40% or more off retail.
  • Not returnable. Customized products, including faceplate designs, are non-refundable, and the page says the same applies to carry cases, cables, ear tips and other accessories, "due to hygiene purposes". If one item in a package is defective, incorrect or missing, the refund or replacement covers only that item.
  • Warranty. The page gives a 1-year warranty on products, excluding carry cases, ear tips and other accessories, and 3 months on cables and adapters, from the date of purchase. It covers factory defects that affect proper function, not damage from human error, negligence, accidents, dismantling, water, abuse or modification (checked 2026-11-11).
  • Not covered or limited. It does not apply to items bought elsewhere (AliExpress, Amazon, local dealers and the like), prize or giveaway items, normal wear or colour change, commercial use, or items that were stolen or went missing. Coverage is limited for products 40% or more off retail, for review units and for items repaired or modified by anyone Linsoul has not authorized.
  • Claims. Email [email protected] with the order number, the issue and photos and videos of the fault. The store may ask for the unit back for a replacement. It covers shipping for some defects reported within 7 days of delivery if the fault can be shown on video or photo; after 7 days the buyer ships it back. For wrong or missing items an unboxing video of the whole sealed parcel is required.

Before you buy

Linsoul says it was founded in 2016 by the Crazy HiFi team to bring Chinese HiFi makers closer to listeners worldwide, and that it now sells other makers' products alongside four brands of its own, THIEAUDIO, Kiwi Ears, ZiiGaat and Tripowin (checked 2026-11-11).

We have not read any independent review of this product or of the store. Ratings and owner reviews shown on the store's own pages are the store's and were not verified.

What we liked

  • The page lists up to 1500mW and a headphone range of 16 to 600 ohms
  • Formats listed are PCM 32Bit/384kHz, DSD256 and MQA 8X, per the page
  • Bluetooth 5.4 with aptX HD, aptX Adaptive and LDAC is listed alongside USB input
  • The page describes a CNC-machined aluminum body and a tube-plus-transistor design
  • One orderable option at $237.15 keeps the choice simple

Worth noting

  • The 1500mW figure has no load stated, so it cannot be tied to a headphone impedance
  • The listing text gives no DAC chip, headphone port types, weight or dimensions
  • The page's sound and latency wording is the maker's claim and cannot be checked from the listing

What we couldn’t verify

  • Per the page, output power is up to 1500mW, but the page gives no load for it, and the listing text gives no DAC chip, headphone port list, weight or dimensions.
  • The page's sound descriptions (warm, soft tube sound, clarity), its ultra-low latency wording and its near-lossless wording are the maker's claims and were not checked here.
  • We have not read an independent review of this product or the store, and the store's own ratings were not verified. We read the store's catalog description only: a specification table or image shown just on the live page was not read.
  • The shipping page names no US, Canada, UK, Australia or New Zealand times or fees: its figures are general and we could not confirm them for these countries.
