IMPRESSIONS APRES 3 MOIS D'UTILISATION.
Après 3 mois d'utilisation, la qualité et la puissance de ce petit ampli demeurent surprenants.
Il faut néanmoins savoir deux choses: le manque de progressivité du réglage de volume évoqué par Quobuzz dépend de l'impédance de votre casque. La progressivité est normale avec un casque à partir de 120 ohms et "délicate avec un 32 ohms. Idem pour le "clong" à la mise sous tension. Léger avec un casque à partir de 120 ohms, redoutable avec mon Beoplay H6, pourtant transcendé par cet ampli avec mon baladeur Fiio mais que je branche et débranche à chaque utilisation pour éviter le claquement sec des transducteurs.

Trés déçu
Le look du preamp est magnifique, l emballage aussi, mais l efficacité du produit n est pas au rendez vous. La hausse de volume en sortie d un iPad par rapport au volume original est infime. J ai acheté ce preamp pour pouvoir écouter des films en roulant dans un van en tournée... et c est pas gagné... à 70 euros le preamp c est très décevant.
Luc , ingé son.

SURPRENANT
Si le look "Star Treck" n'apporte rien d'autre que faire remarquer cet ampli, sa facilité à driver des casques nécessitant beaucoup de courant, comme mon vieil AKG 501 est surprenante au regard de son prix, surtout en promotion.
Bel emballage, jolie notice en mandarin (mais mode d'emploi évident) câble micro usb et câble de liaison Monster fournis. Ce câble Monster est très bon, mais court et assez rigide. Bien sur un Dap ou un smartphone mais trop court pour une tablette. Le niveau sonore est progressif sur une sortie casque (smartphone ou tablette, mais plus rapide sur la sortie ligne d'un DAP comme le faisait remarquer le test de Quobuzz..
Un excellent achat, sans concurrence dans cette gamme de prix.
