I have a DUAL 1019 turntable that works well when paired with my pioneer SA-720 amplifier but the phono inputs on my amplifier were mediocre at best. Pairing this with the BOX X-1 by Fosi was a outstanding match. Sound quality is superb . This unit will drive the line in on you headphone amp, modern bookshelf system or PC. Outstanding product, no doubt.

Ce préampli Phono fonctionne bien , aucun bruit de fond;
à mettre sous tension avant d'allumer l'ampli de puissance en mettant le volume à Zéro.
La sortie casque n'a pas de réglage de volume par potentiomètre. Dommage .
