Excellent préampli à tubes très dynamique et musical
Commande expédiée très rapidement et reçue également en un délai vraiment très court avec DPD. Une belle surprise que ce préampli à tubes qui prend le relai d'un vieux ampli intégré de classe AB. Les enceintes Auditor NX-70 sont ressuscitées !

Ouverture du son
Je viens d'une préamp FX-AUDIO TUBE-03 à Tubes 6K4, et je trouve une nette différence d'ouverture de son.
Par contre, moins puissant j'ai l'impression, le volume faut le pousser !!
Par contre, quel son supérieur !!!
Seul bémol, le bluetooth qui n'est vraiment pas excellent, et je le compare au bluetooth du AIYIMA A08 PRO qui, je trouve, reste meilleur.

Sinon, très bon son et j'aime son esthétique avec cette petite lueur bleue des tubes ...
