Gustard R30 R-2R DAC Review
An R-2R DAC from Gustard whose page lists a self-designed, fully discrete R-2R ladder network, a True-1 Bit DSD converter with native DSD1024 support and an SC-Cut OCXO clock. It costs $3239.99 in Black or Silver.
Our verdict
An R-2R DAC for someone who wants a listed fully discrete ladder network, native DSD1024 support and an OCXO clock with external clock connections, at $3239.99 in Black or Silver. Look elsewhere if you need listed PCM rates or a connector list, since the listing text gives neither. The main caveat is that the page's claims about purity, detail and natural sound are the maker's words and were not checked here.

Native DSD1024 support through a True-1 Bit converter is the headline claim on the R30 page, which also lists a self-designed, fully discrete R-2R ladder network DAC. The page lists an SC-Cut OCXO clock paired with the GCLK-02 module, says external clock connections are supported, and names two toroidal transformers that power the digital and analog circuits separately. The R30 costs $3239.99 in Black or Silver.
Options and pricing
There are two options, Black and Silver, at the same $3239.99, so the color is the only choice and the price stays put. The page shows $3599.99 crossed out beside the price, the store's own comparison that we did not check. The listing text gives no weight, dimensions, input list or output connectors for either option.
How it compares
The MUSICIAN Taurus is $3610 and the MUSICIAN Aquarius R2R DAC is $2943.99, with neither entry showing a spec line. The GUSTARD DAC-X30 is $2699.99 and its entry mentions ES9039SPRO and ES9039PRO, while the R30 page names a discrete R-2R ladder network and no chip model.
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.

What we couldn’t verify
- Per the page, the descriptions of pure analog sound, a pristine high-definition sound and a smoother, more natural listening experience are the maker's claims and were not checked here.
- The page says the DSD1024 converter gives an oversampling ratio 16 times greater than DSD64, a comparison that was not checked here, as was the 1Hz-level locking claim.
- The listing text gives no PCM sample rates, input list, output connectors, weight or dimensions, and the page shows $3599.99 crossed out as the store's own comparison.
- 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.
