Cayin iDAC-8 Desktop DAC Review

A desktop DAC listed at $1,199.99 whose pictures name an AK4191 modulator with two AK4499EX chips, XLR and RCA outputs and a tube or solid-state output setting. It suits a line-level chain; the store title says headphone amplifier, but the pictures read for this review list no headphone output.

Our verdict

A fit for buyers who want a desktop DAC with XLR and RCA outputs, a Pre Out mode and a choice of tube or solid-state output at $1,199.99. Look elsewhere if you need a headphone output, which the pictures read do not list, or a US plug, since every option is 220V with an AU or EU plug. No independent test was checked for this review: every figure is the store's own.

Best for
Listeners who want a DAC with XLR and RCA outputs and a tube or solid-state setting.
Skip if
You need a headphone output (none appears in the pictures read) or a mains plug other than AU or EU.

Why 3.3/5: Held back by a page with no specification list as text, with most claims in pictures only some of which were read, by the store's own terms contradicting each other, and by figures that are the store's own with no independent test checked for this review.

At $1,199.99 on the page, the Cayin iDAC-8 is a desktop DAC whose pictures show an AUDIO D/A CONVERTER front label, an AK4191 modulator with two AK4499EX chips in Mono Mode, and separate output tables for a solid-state and a 6H6b-B vacuum-tube setting. Analog outputs are XLR x2 and RCA x2, and the digital inputs run from I2S and USB to AES/EBU, coaxial and optical.

Options and pricing

Four options are listed at $1,199.99 each, all orderable when the page was read: black or white, each named 220V with an AU plug or an EU plug. The price is the same for every combination, and no option is named for a US plug or another mains voltage. A rear label in the pictures reads ~220V 50Hz 30W, so check the mains supply before ordering.

How it compares

The xDuoo TA32 costs $999 against $1,199.99 here and is named a DAC and tube balance headphone amplifier, a headphone stage that the pictures read for the iDAC-8 do not list. The FiiO K9 at $499.99 and the FiiO WARMER at $349.99 are also named DAC and headphone amplifier combinations, so they suit a desk with headphones. The iDAC-8's pictures describe Pre Out as a variable output for a power amplifier or active speakers, which fits a line-level chain instead.

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.

What we liked

  • AK4191 modulator with two AK4499EX chips in Mono Mode, as listed in a pictured spec table
  • Balanced XLR x2 and single-ended RCA x2 outputs, each with Line Out and Pre Out modes in the pictured tables
  • Six digital inputs listed: I2S, USB, coaxial on RCA and BNC, AES/EBU and optical
  • USB input listed at PCM 16Bit to 32Bit, 44.1kHz to 768kHz and native DSD-64 to DSD512
  • Separate output figures for the solid-state and vacuum-tube settings, with a 47kΩ load stated for levels

Worth noting

  • No headphone output appears in the pictures that were read, although the store title calls it a headphone amplifier
  • All four options are 220V with an AU or EU plug; no US plug option is listed
  • In the pictured Line Out table the vacuum-tube settings list higher THD+N than solid state: ≤0.05% against ≤0.0007% on RCA and ≤0.8% against ≤0.0006% on XLR
  • The I2S input uses an HDMI Type A connector that a picture says is not compatible with standard HDMI devices
  • The specification list is a set of pictured tables rather than text, and not all 18 pictures were read

Questions before you buy

Does the iDAC-8 have a headphone output?

None is listed in the pictures that were read: the analog outputs are XLR x2 and RCA x2, and the front panel picture shows no headphone jack. A picture also names the iHA-8 as the i-series headphone amplifier, so the store title's headphone amplifier wording is unconfirmed.

Which digital inputs and formats does it list?

I2S on an HDMI Type A connector, USB Type-B, coaxial on RCA and BNC, AES/EBU on XLR3 male and optical TOSLINK. USB and I2S list PCM 16Bit to 32Bit at 44.1kHz to 768kHz and DSD-64 to DSD512; AES/EBU and coaxial list PCM 16Bit to 24Bit at 44.1kHz to 192kHz, and optical 44.1kHz to 176.4kHz, with DoP64 for DSD on those three.

How are the tube and solid-state settings described?

A picture claims the tube setting uses a 6H6b-B dual triode per channel and the solid-state setting uses Texas Instruments low-noise op-amps. The output tables list the two settings in separate columns, with RCA and XLR figures for each.

Where does HiFiGO ship from, and how long does it take?

From its warehouse in China, usually 1-3 business days after the order. The shipping policy gives 1-2 weeks to the US by Priority (6-10 days by Premium), both with duties and taxes prepaid, 2-3 weeks to Canada, 1-2 weeks to the UK and 10-15 days to Australia. Express couriers take 3-7 days, but the buyer pays any duties.

Can I send it back if I change my mind?

HiFiGO gives 7 days to report an item that arrives dead, damaged or wrong. Its policy also describes 30-day returns, but requests 7 to 30 days after delivery lose 30% of the MSRP plus shipping both ways and duties, and the FAQ on the same page says no refund or exchange after 7 days. Ask [email protected] before you open the box.

What warranty does HiFiGO give?

One year from the order date for parts and labor, for faults in build or materials (the policy names desktop DACs and amps, IEMs and dongles; cables and adapters get three months). HiFiGO chooses repair or replacement, the buyer pays the shipping, and a faulty item is serviced rather than refunded. Claims go to [email protected].

What we couldn’t verify

  • The store title calls it a tube DAC and headphone amplifier, but no picture that was read lists a headphone output (outputs: XLR x2, RCA x2), and a picture names the iHA-8 as the series' separate headphone amplifier.
  • The tube and solid-state circuit details (6H6b-B dual triode, Texas Instruments op-amps) and the Pre Out and Line Out descriptions are claims made in pictures, not checked here.
  • Every spec figure comes from pictures of tables, and not all 18 pictures were read; the THD+N, SNR and level figures give conditions (1kHz, Fs=192kHz, 47kΩ load, Volume = 81 for Pre Out THD+N) but remain the page's own claims.
  • HiFiGO's policy pages contradict each other: 30-day returns with a 30% restocking fee in one place, no refund or exchange after 7 days in the FAQ.
  • HiFiGO's pages name no company, street address or phone number; the only contact given is [email protected].
