E1DA 9038SG3 Susumu3000 USB DAC/Amp Review

E1DA's Susumu3000 edition of the 9038SG3 is a USB DAC and headphone amp built on the ES9038Q2M chip, listed from $100. Its page carries a spec section: a balanced 2.5mm output, over 340mW at 32Ohm, 10g, 48x22x9mm and no internal battery. The same page also describes the third-generation 9038SG3 changes and the earlier 9038S in one text, so some figures appear twice and do not always match.

Specifications

Options and pricing

Two options are listed: the 9038SG3 Susumu3000 at $100 and the DAC with a C to C cable at $103, both orderable when the page was read. The page text does not describe the cable, its length or its connectors. It warns that no 2.5/3.5mm jack adaptors are allowed and that they can kill the DAC, and says iOS and Android devices need a Camera_Adapter and a USB OTG Y-splitter cable respectively to start OTG operation.

How it compares

The HiBy FC5 2025 With Display Dual CS43198 Portable USB DAC&AMP and the xDuoo LINK10 Dual CS43131 USB DAC & AMP are both $99 against $100 here; their titles name dual CS43198 and dual CS43131 chips, where this page names an ES9038Q2M. The LINK10 line lists PCM 32Bit/384kHz and Native DSD256, the range the E1DA text claims, while the E1DA spec section says PCM up to 24b/192kHz. The Muse HiFi M3 Ultra ES9028Q2M Vacuum Tube Portable DAC & Headphone AMP is $104.99. Choose the E1DA only if your cable is balanced 2.5mm, since the page text lists no other output.

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.
