AM5
Il prodotto è potente e di buona qualità, manca la cosa più importante che deve esserci in un amplificatore di qualità e cioè: l'uscita da 2.5" bilanciata. Per questo motivo per me è stato un acquisto inutile buttando via 100€, considerato che la maggior parte delle mie cuffie posseggono cavi bilanciati. Fiio hai toppato!
fiio am5
Il prodotto da sicuramente un vantaggio in più con cuffie di una certa impedenza tipo le sennheiser hd 660s. Ottimo playstereo che come sempre da un'assistenza al top rispondendo sempre in tempo utile per varare l'acquisto, un grande plauso.
- DeejayAlex73Ho questo lettore nuovo mai usato, con la sua scatola immacolata, praticamente si può vendere come nuovo acquistato da voi (Playstereo) qualche mese fa. Considerato che non lo uso ed è sprecato tenerlo, c\'è un sistema per potermelo ritirare e ricavarci qualcosa? Grazie
- PlayStereoBuonasera, quale lettore possiede? O si tratta del modulo di amplificazione? In ogni caso per questo discorso potrebbe cortesemente contattarci privatamente su info@playstereo.com ?
- DeejayAlex73Un AM5 della Fiio pari al nuovo
