preampli HAFLER DH 110 (VENDU)

[gentlegiant]

bonjour a tous

Type : preamplificateur
Marque :HAFLER
Modèle et options : DH 110

un des meilleurs produits issus du savoir faire d'un des illustres "concepteurs ricains" David Hafler
le peamp DH 110 a ete concu pour etre en binome avec le tres renome bloc de puissance P4000
pour avoir cotoyé les deux je trouve le preampli superieur au P4000 c'est dire
la partie phono est de tres haute "volée",les entrées lignes etant du meme niveau

a l'ecoute ce qui carracterise le DH 110 c'est une bande passante ultra large avec de l'aeration et un sens
du detail et de la cohesion des registres des plus travaillés
qualite des timbres (medium/aigu) , tres belle tenue du grave sont au rendez vous
bref ca fait de la "musique"
