Yulong DP1 Network USB Interface Review

The Yulong DP1 is a network and USB digital interface that HiFiGO lists at $939 in black or white under the title DAART Yulong DP1, although the pictures read for this review show only a YULONG AUDIO logo. A spec table pictured on the page gives PCM up to 32Bit/1536KHz on its network, USB and I2S paths and native DSD64/128/256/512/1024, with outputs on AES, coaxial, optical, I2S and a BNC clock connector, THD+N of 0.000008% and a dynamic range of 140dB.

Specifications

Options and pricing

Two options are listed, DP1-Black and DP1-White, both at $939 and orderable when the page was read. The pictures show a rear panel with AES/EBU, coaxial, BNC clock, optical, an HDMI-shaped I2S port, a type-B USB port, a LAN port, a rocker power switch and an AC input marked 220/110V 50/60HZ, plus a front IPS LCD and a single control knob. No in-the-box list appears in the pictures read for this review.

How it compares

The Gustard U26 USB Digital Interface is listed at $999.99 against $939 here and is named a USB interface, while the DP1 is named a network and USB interface. The FiiO S15 AK4191+AK4499EX Desktop High-Res Audio Streamer at $1,099.99 is named a desktop high-res audio streamer with AK4191+AK4499EX in its name; the DP1's pictured rear panel shows digital outputs only, which suits a buyer who already has a DAC. The Gustard Audalytic DR80 / DR80N Discrete R2R Streamer DAC starts at $699.99 and is named a discrete R2R streamer DAC.

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.
