QULOOS MC01 and MC01se DAC/Amp Review

Quloos pairs two CS43131 DAC chips in the QLS MC01 and MC01se, which the store lists on one page from $215.99. Both decode PCM up to 32-Bit/384kHz and native DSD256, per the page, and the page spells out one difference: the MC01 has 3.5mm single-ended and 4.4mm balanced jacks while the MC01se has only the 3.5mm jack. An OLED display and independent volume control are listed.

Specifications

Options and pricing

Four options are listed: MC01 in Grey or Red at $224.99, with a crossed-out price of $249.99 on the page, and MC01se in Grey or Red at $215.99, with a crossed-out price of $239.99. All four options were marked orderable when the page was read. The page text lists no cable, case or in-the-box items and does not name the USB connector.

How it compares

The SMSL DS20 is $189.99 and its title lists four CS43131 chips against the two named here. The xDuoo LINK3 costs $219 and its spec line goes up to 32-bit/768kHz PCM and native DSD512, above the 32-Bit/384kHz and DSD256 on this page. The Moondrop Moonriver 3 is $219.99 and uses CS43198 chips, a pair per its title, rather than CS43131. The MC01se suits a 3.5mm-only buyer, the MC01 suits balanced users, and the LINK3 suits buyers who want the higher PCM and DSD ceiling.

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.
