AUNE X8 Desktop USB DAC Review

The AUNE X8, from a China-based maker according to the page, is listed at $224.25 as a desktop DAC with USB Type-B, coaxial and optical inputs and RCA outputs. The page gives PCM up to 32-Bit/768kHz and native DSD512 over USB, a 2.0Vrms output, THD+N of 0.0006% and a signal to noise ratio of 117dB. It also says the op-amps can be swapped and names seven filter options.

Specifications

Options and pricing

Five options are listed, all $224.25 against a crossed-out price of $299, and all orderable when the page was read. They combine Silver or Black with a US (110V), EU (230V) or UK (230V) plug; four are labeled Package 1 and the Black US-plug option is labeled Package 2. The specification section describes a 001 package with OPA2134 and NJM5532 op-amps and a 002 package with five op-amp types, without saying how they match those labels. The package list names a USB cable, a power supply, an extractor clip, a carry box and a user guide.

How it compares

The SMSL SU-6 at $169.99 has Bluetooth 5.0 with LDAC in its name, whereas the X8 page says Bluetooth: No; both list 32-Bit/768kHz PCM and DSD512. The TOPPING DX5 II is $299 and is named a DAC and amp, while the X8 title says DAC Amp but its page lists only RCA outputs. The X8 at $224.25 is the one for swappable op-amps and a variable pre-amp output; the SU-6 is the one for wireless input.

Shipping, returns and warranty

HiFiGO sells from hifigo.com and says every order leaves its warehouse in China, usually 1-3 business days after it is placed, and says its delivery times are estimates, not promises. Its shipping policy gives the United States 1-2 weeks (about 10 days on average) by Priority and 6-10 days by Premium, both with duties and taxes prepaid by the store; Canada 2-3 weeks; the United Kingdom 1-2 weeks; and Australia 10-15 days. Express couriers (DHL, UPS, FedEx) take 3-7 days, but then the buyer pays any duties and taxes. No shipping page names New Zealand, PO boxes are not accepted, and the free-shipping thresholds differ between the store's own pages, so check the cart. One of its two shipping pages adds that a lost parcel on an order above $50 gets only a 50% refund. A US buyer reported a $40 tariff charge in August 2025, after which HiFiGO said it had added a customs notice at checkout.

Read the return terms before you order. The homepage advertises 7-day returns. Both of HiFiGO's policy pages offer a 7-day dead-on-arrival cover (a replacement or a full refund, with the return postage refunded) and also describe 30-day returns, but a request made 7 to 30 days after delivery loses 30% of the MSRP as a restocking fee (10% more if the packaging is incomplete), plus shipping both ways and duties, and the FAQ on the same pages says there is no refund or exchange once 7 days have passed. One version recommends reselling an opened product locally. Custom IEMs and custom cables cannot be returned, no return address is published, and buyers describe sending items back to China.

HiFiGO's warranty runs one year from the order date for parts and labor; its policy names desktop DACs and amps, IEMs and dongles at one year and gives cables and adapters three months. HiFiGO decides between repair and replacement, the buyer pays the shipping, and faulty items go back for service, not for a refund. Claims go to [email protected], the only contact the store lists: its pages name no company, street address or phone, and its terms are governed by the laws of China.

On Trustpilot, HiFiGO had 4.6 out of 5 from 378 reviews when we checked on 2026-10-28 (91% five-star, 5% one-star), and it had replied to about 75% of negative reviews; Trustpilot notes the store has not invited customers to review recently. The one-star reviews mostly concern the short return window and the deductions on returns, items listed in stock that turned out back-ordered, slow email support and a tariff charge on a US delivery in 2025. HiFiGO says its products are genuine and come in the brands' retail packaging; it does not claim to be an authorized dealer.
