E1DA PowerDAC v2.1 USB DAC Review

The PowerDAC v2.1 from E1DA is a USB-powered DAC with a balanced 2.5mm TRRS output, and the store lists it at $79.99 in a bundle with a 2.5/3.5 adapter and a Type B to A cable. The page presents it as the PDv2 reworked so it can also drive unbalanced headphones, with a CT7601 Comtrue USB audio bridge and a soft-start function. Its spec section gives 68g and over 320mW at 32Ohm, and the page itself says the unit has no headphone amplifier stage.

Specifications

Options and pricing

One bundle is listed, Power DAC v2.1 plus the 2.5/3.5 adapter and a Type B to A cable, at $79.99, and it was orderable when the page was read. The page says the E1DA adapter is for the unbalanced mode, yet another note says 2.5/3.5mm jack adaptors are not allowed and can ruin the DAC. The page does not reconcile the two and tells buyers to read its FAQ before buying.

How it compares

The DUNU DTC480 is listed from $69.99 and the Fosi Audio DS3 at $84.99, and both name chip-based DAC designs in their titles (dual CS43198 and ES9039Q2M) where this page's text names no DAC chip. The xDuoo LINK10 is $99 and its spec line lists PCM 32Bit/384kHz and Native DSD256, against the PowerDAC's USB PCM up to 24b/192kHz and no DSD listed. The PowerDAC v2.1 suits buyers who want a balanced 2.5mm output and a spec table with figures; the LINK10 suits those who want higher listed sample rates, and the DTC480 or DS3 those who want a named chip.

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.
