E1DA 9038D6K USB DAC/Amp Review

At $135, the E1DA 9038D6K is a 12g USB DAC and headphone amplifier with a single unbalanced 3.5mm output. The page says it comes in the same case as the 9038SG3 and lists the ES9038Q2M chip, 180mW at 32 Ohm and 120mW at 16 Ohm. Its specification section gives PCM up to 32b/384kHz and DSD256 over USB-C and a frequency response of 5-80kHz.

Specifications

Options and pricing

One option is listed, 9038D6K with Bundle 1, at $135, and it showed as orderable on the day the page was read. The page does not say what Bundle 1 contains, so cables or other items cannot be confirmed from the listing. The only output is a standard unbalanced 3.5mm jack, with no balanced or plug variants offered. The page asks buyers to read the FAQ it links to before buying.

How it compares

At $135 the 9038D6K sits between the TOPPING L30 Headphone Amp at $97.49, which is named as an amplifier only, and the FiiO K11 R2R High-Performance Desktop DAC / Headphone AMP at $169.99, a desktop unit whose spec reads Fully Differential 24-Bit R2R Resistor Array. The 9038D6K is the small USB-powered option with one 3.5mm unbalanced output. The SMSL DS300 High-Performance MQA DAC & Headphone Amplifier at $188 is a desktop DAC and amp; the 9038D6K suits listeners who want something smaller and cheaper.

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.
