Have you read this? https://www.head-fi.org/showcase/hifiman-deva.24334/reviewsJust found HIFIMAN release the wired version Deva secretly at $219. https://store.hifiman.com/index.php/deva.html
Is it worth to buy? I heard that you can expect great sound quality from them with a decent amp/DAC. Is it true? I'm not into the Bluetooth dongle so curious about the wired version. Anyone who bought it can suggest?
