FiiO AIR AMP Streaming Power Amplifier Review

FiiO's AIR AMP folds a TI TPA3255 Class-D amplifier, an ESS ES9020Q DAC and a network streamer into one desktop unit listed at $299.99. The page lists 120W at 4Ω with the default 48V/5A supply and 200W at 4Ω with a 48V/10A one, PCM up to 32bit/768kHz, native DSD512 and an input list that includes Bluetooth V5.2.

Specifications

Options and pricing

Two options are listed, AIR AMP Black and AIR AMP Silver, both at $299.99 and both orderable when the page was read. The page names no difference between them beyond color. The text calls the 48V/5A supply included and the 48V/10A one an upgrade; the page lists no option or price for the larger supply and gives no in-the-box list.

How it compares

The SMSL AO200 Digital Amplifier Bluetooth 5.0 Balanced Input at $279 and the TOPPING PA5 Fully Balanced Class D Power Amplifier at $226.85 are named as amplifiers; the AIR AMP at $299.99 is the one whose spec line names a DAC, and its page adds network streaming. The AO200 has a balanced input in its name and the PA5 is fully balanced class D. Choose the AIR AMP for digital inputs and streaming in one box.

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.

FiiO's own notice "A letter to FiiO fans" (undated) lists HiFiGo among sellers it has not authorized and recommends buying FiiO products from local agents. FiiO says it still services genuine products bought from such sellers if the buyer emails [email protected], but the buyer pays the freight and duties if a unit must go back to 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.
