HiBy RS8 II DAC and Amp Review
A DAC and amplifier from HiBy, listed at $3899 in Black or Gold. The page describes an in-house Darwin III R2R and FPGA DAC design and THD below 0.0008%, but its body text names the product S8 II, which makes some figures uncertain.

Our verdict
A high-priced DAC and amplifier for someone who is drawn to an in-house R2R and FPGA DAC design and accepts that the page text is partly written for another model name. Look elsewhere if you need output power, inputs, outputs or sample rates, because the listing text gives none. The main caveat is the S8 II wording: confirm which model the figures describe before paying $3899.
- Best for
- Someone who wants an in-house R2R and FPGA DAC design and can confirm the model details first.
- Skip if
- You need published output power, input and output lists or sample rates, which the listing text does not give.
HiBy's RS8 II page centers on a DAC architecture it calls Darwin III, which the page describes as an in-house design combining R2R technology with FPGA processing. The same text also describes a Qualcomm Dragonwing QCS8550 processor, 16GB of RAM, 512GB of storage and a 411g body, but it names the product S8 II in those passages. The page lists THD below 0.0008%. The store lists it at $3899 in Black or Gold.
Options and pricing
There are two orderable options, Black and Gold, both at $3899. The page shows no crossed-out price and gives one description for both colors. Because the body text calls the product S8 II, it is unclear whether the processor, memory and weight figures belong to the RS8 II sold here, so treat them as unconfirmed.
How it compares
The RS8 II at $3899 is priced above every entry in this comparison, including the Shanling EM7 at $1999, whose listing text mentions an ES9038Pro DAC chip where the RS8 II page names an in-house Darwin III design. The MUSICIAN Monoceros costs $1169.99 and the GUSTARD H26 $1034.10, and neither page lists a processor or storage.
Shipping
- Methods and costs. The store's shipping page offers Standard Shipping (4PX, Yanwen or Yun Express), free for most countries, and Express Shipping (DHL Express, FedEx or SF Express) at 15-50 USD depending on the country, free for orders over 270 USD in most countries (checked 2026-11-11).
- Large items. The page says headphones and desktop DAC/AMPs count as large items, for which Express is free only for orders over $499.99.
- Delivery times. It says an in-stock order ships within 3 working days, Standard takes about 2 weeks after shipping out (up to 1-3 months for some countries, and the store makes no refund for that transit time) and Express takes about 3-7 days. Festive seasons and other circumstances can change the timing.
- Taxes and fees. The buyer pays any customs, import or processing fees. The page says Standard via YunExpress is tax-inclusive for some countries, that remote areas can carry extra Express charges, and that a parcel refused or left uncollected over taxes is deducted two-way freight and may be destroyed with no refund.
- Where it ships. The page says the store can generally ship to most countries by Express and many by Standard, and to confirm Standard with the team for your country. It cannot ship to PO boxes or APO/FPO addresses and can only use Express to Hawaii. It does not name the US, Canada, the UK, Australia or New Zealand, so confirm before you pay.
- Lost parcels. If a parcel has been in transit for at least 3 months, the page offers a one-time reshipment or a full refund for orders under $50 and a 50% refund for orders above $50.
Returns and warranty
- Returns. The return page allows returning any non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying the shipping. Email [email protected] within that period; the store asks for the return to be shipped within 5 working days of the RMA instructions and in most cases processes a refund within 5 business days of inspecting it (checked 2026-11-11).
- Opened items. A product opened within the first 7 days after delivery can be returned for the price minus a restocking fee of 35% of its retail value, including when it still works properly.
- Refund or credit. The buyer can choose a refund to the original payment method (PayPal or card) or store credit; with no answer within 48 hours of confirmation the default is store credit, which can also be prioritized during promotions, final-sale events and for items 40% or more off retail.
- Not returnable. Customized products, including faceplate designs, are non-refundable, and the page says the same applies to carry cases, cables, ear tips and other accessories, "due to hygiene purposes". If one item in a package is defective, incorrect or missing, the refund or replacement covers only that item.
- Warranty. The page gives a 1-year warranty on products, excluding carry cases, ear tips and other accessories, and 3 months on cables and adapters, from the date of purchase. It covers factory defects that affect proper function, not damage from human error, negligence, accidents, dismantling, water, abuse or modification (checked 2026-11-11).
- Not covered or limited. It does not apply to items bought elsewhere (AliExpress, Amazon, local dealers and the like), prize or giveaway items, normal wear or colour change, commercial use, or items that were stolen or went missing. Coverage is limited for products 40% or more off retail, for review units and for items repaired or modified by anyone Linsoul has not authorized.
- Claims. Email [email protected] with the order number, the issue and photos and videos of the fault. The store may ask for the unit back for a replacement. It covers shipping for some defects reported within 7 days of delivery if the fault can be shown on video or photo; after 7 days the buyer ships it back. For wrong or missing items an unboxing video of the whole sealed parcel is required.
Before you buy

What we liked
- The page names its DAC approach, Darwin III, as an in-house R2R and FPGA design
- A THD figure below 0.0008% is listed, per the page
- The page lists 16GB of RAM, 512GB of storage and a 411g weight, though under the name S8 II
- Both colors cost the same $3899
Worth noting
- The body text calls the product S8 II while the title says RS8 II, so some figures may belong to another model
- The listing text gives no output power, input or output list, DAC chip model, sample rates or battery details
- The page mixes DAC and amplifier wording with portable-player wording (processor, storage), so the unit's role is unclear
- Sound and design statements are the maker's wording and cannot be checked from the listing

What DAC does the RS8 II list?
The page names the Darwin III, which it calls a fully in-house developed DAC architecture combining R2R technology with FPGA processing. It names no DAC chip model.
Why does the page mention an S8 II?
The body text refers to the S8 II when it lists the Qualcomm Dragonwing QCS8550 processor, 16GB of RAM, 512GB of storage and the 411g weight, while the title says RS8 II. The page does not explain the difference.
What colors can I order?
Black and Gold, both at $3899; the page shows two orderable options.
Can I return it if I change my mind?
The return page allows returning a non-customized product that is still factory sealed within 30 days of receiving it, with the buyer paying shipping. An opened product returned within 7 days carries a 35% restocking fee. Refunds go to the original payment method or to store credit, which is the default if you do not choose.

What we couldn’t verify
- The body text names the product S8 II while the title says RS8 II, so the processor, memory, storage and 411g figures may describe another model; the page does not explain this.
- Per the page, the THD below 0.0008% and the claims about digital artifacts and adaptive amplification are the maker's and were not checked here.
- The page's sound descriptions are the maker's claims; the listing text gives no output power, inputs, outputs, DAC chip model, sample rates or battery details.
- We have not read an independent review of this product or the store, and the store's own ratings were not verified. We read the store's catalog description only: a specification table or image shown just on the live page was not read.
- The shipping page names no US, Canada, UK, Australia or New Zealand times or fees: its figures are general and we could not confirm them for these countries.
