On le trouve notamment sur le site Xtenik pour 110$ https://www.xtenik.com/product/xduoo-xp-2/, ou chez Penon Audio voir Audiophonics pour ceux voulant acheter en Fr (et il avait aussi fait l'objet d'un drop sur Massdrop en décembre dernier). J'en refait une review dans la section adéquate dans 2 ou 3 semaines, le temps de bien le connaitre et de l'écouter sur tous mes intras/casques !
