GUSTARD X30 Network Streaming DAC Review

The GUSTARD X30 pairs four ES9039SPRO chips, two per channel according to a picture on its page, with LAN streaming, and HiFiGO lists it at $2,999.99 in black or silver. The description is 25 pictures with no specification text. Those read for this review show XLR and RCA line outputs, USB, LAN, AES, coaxial, optical and IIS inputs, a 10MHz clock input and an R2R relay volume described as a passive analog preamp.

Specifications

Options and pricing

X30-BLACK and X30-SILVER are the two options, each $2,999.99 and orderable when the page was read. The pictures read name a 220V/110V voltage switching callout and an AC115V/230V 50/60Hz supply. No in-the-box picture was among those available for this review, so box contents are unknown.

How it compares

The GUSTARD X26III Network Streamer ES9039SPRO X2 DAC costs $1,599.99 against $2,999.99 here and is named with ES9039SPRO X2, where this unit's name says Quad ES9039SPRO*4. The GUSTARD R30 Fully Discrete R2R Streaming DAC costs $3,599.99 and has Fully Discrete R2R in its name, not ES9039SPRO. The X30 suits buyers who want an ES9039SPRO-based DAC with four chips and LAN playback; the X26III suits a smaller budget.

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.
