GUSTARD AUDALYTIC AH90 Streamer DAC Review

GUSTARD's AUDALYTIC AH90 combines a network streamer, a DAC and a headphone amplifier, and the store lists it at $599.99 in Silver or Black. Per the page it uses AKM's AK4499EX DAC with an AK4191 modulator, an FPGA architecture and an XMOS XU316 USB processor. It takes LAN input for Roon Bridge, Apple Airplay, UPnP, Spotify and Tidal, and it has 6.35mm single-ended and 4.4mm balanced headphone jacks, with 1W maximum at 32Ω through the balanced connection.

Specifications

Options and pricing

Two options are listed, AUDALYTIC AH90 Silver and AUDALYTIC AH90 Black, both at $599.99 and both orderable when the page was read; the option group is labeled Color. The page lists a remote control and an OLED display screen among its features and gives 295x265x85mm as the package size and 220x170x50mm as the product size. The page text lists no package contents or cables.

How it compares

The SMSL D400 MK2 is $649 and names the same AK4191 and AK4499EX pair as a desktop DAC, against $599.99 here with streaming and headphone jacks on the AH90 page. The TOPPING D70Pro is $699 and names Bluetooth 5.1 and LDAC, which the AH90 page text does not mention. The SMSL SU-9 PRO is $499.99 with MQA and BT 5.0 in its name. Neither the D400 MK2 nor D70Pro name mentions streaming, so the AH90 suits buyers who want it built in.

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.
