ddHiFi RC20A RCA Cable, 20cm and 40cm Review
A ddHiFi RCA cable in 20cm and 40cm options, listed from $67.99 with a crossed-out $79.99. The page's pictures give a three-strand spiral winding PCOCC conductor and weights of 21g and 29g, and recommend it for small desktop DACs and amplifiers. It suits buyers who connect such gear.
Our verdict
A fit for a buyer who wants a 20cm or 40cm RCA cable for small desktop DACs and amplifiers, as a picture recommends, and can work from picture figures. Look elsewhere if you need an in-the-box list or a stated count of cables per purchase, since the pictures show two cables while the option names say 1pair. The main caveat is that every spec figure comes from pictures and the lengths exclude the plugs.

Why 3.3/5: What holds it back: no specification list as text, claims that sit mostly in pictures, the store's own terms contradicting each other, and no independent test of this model checked for this review.

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.
Cables and adapters get three months of warranty from the order date, against one year for DACs, amps and IEMs; a note on the same page also excludes cables from returns for hygiene reasons, while the FAQ says a cable can come back in its original condition. HiFiGO decides between repair and replacement and the buyer pays the shipping. Claims go to [email protected], the only contact the store lists: its pages name no company, street address or phone.
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.

- A pictured specification list names the plug materials: gold-plated copper core, resin inner cover and aluminum alloy shell
- A pictured specification list says the black plug is for the left channel and the red plug for the right
Worth noting
- The pictures read give no in-the-box list
- The printed lengths exclude the plugs
