Excellent DAC - Horrible Streamer !
The DAC is excellent however the streaming module is an afterthought that is very buggy ! There are regular drop outs when streaming from Roon and the device will register itself with a new MAC-adress on your network at EVERY startup. This has been confirmed by multiple users on head-fi.org forums. Also note that this is not a Roon Ready device, it's a Roon bridge which is NOT officially supported by Roon. In fact, Gustard does not have a license to claim Roon compatibility and it does not appear in the list of Roon compatible devices (https://roon.app/en/partners). The manual is an auto-translate from the Chinese version. I now stream to a Raspberry Pi running RoPieee, which is then connected via USB to the Gustard, this combo works very well. But the Gustard as a solo streaming solution ? Absolute crap.

Perfect sound & DSD direct via UPnP works!
Continuing from my previous appraisal below: please do not do anything wrong as directed by some extremist forums: just downgrade to Gustarender 1.41 (when you have received 1.43) - BalenaEtcher or USBImager would do. Install USB drivers fist (for C port above ETH). Suddenly TIDAL HiRes & MQA works without any outages and you can stream DSD from your own UPnP resources instantly! I am not a user of Roon, and I will never be - no reason for it. Thank you Audiophonics for the support!

Perfect sound but beware of DSD direct!
Sound for its price its unbeatable. But beware of DSD direct - no way to get DSD native in LAN mode - it is converted to hires PCM. Fmv 1.43. Awaiting DAC patch from Shenzenaudio.

I echanged A22 to A26 and this was good step
I have Gustard A22 for over 2 years, it goes to second system and A26 exchanged it in main system. I short - the same good, natural, full and balanced sound, with little improvement of low frequency, new model is more accurate, more detailed. And has improvements like input for external clock (I will add in future) and with LAN input! Only screen is smaller than in A22, but looks more stylish. Important - new model heat-up less than A22

Très Prometteur!!
A la sortie du carton on ne peut que constater que c'est un très bel appareil et l'impression d'une écoute trop "contenue" disparait rapidement au bout de 3-4h sous sous tension. Un réel potentiel commence à poindre sur les timbres et la largeur de scène déjà impressionnante.
Sinon pas de frayeur à avoir sur la notice vraiment très très succincte pour la partie Streamer de l'appareil. Ce dernier est vu 15s après démarrage par Roon et HQPlayer. Plutôt "user-friendly" donc mais à confirmer.
Je reposterai un avis d'ici qq jours sur le son et l'utilisation.

GUSTARD A26
Perfect sound and trouble-free operation.
