Amplificatorul este construit in jurul unui integrat foarte laudat (Tripath TA2020 ) si functioneaza in clasa T. Din review-urile pe care le-am citit , majoritatea au declarat ca sursa de alimentare inclusa sau externa , furnizata la achizitionare , nu este suficient de bine filtrata si ca cel mai bine functioneaza alimentat dintr-un acumulator de 12V. Deci poate fi un amplificator destul de bun... factorul decisiv vor fi boxele.Din pacate boxele nu se potrivesc cu acest amplificator. Ai nevoie de boxe cu sensibilitate mare , minim 93Db/w/m.Eu personal a-si construi niste VTP-uri pe 2 cai sau cu un difuzor de banda larga , de calitate.

Sa nu comparam pe king kong ala cu ceva amplificator Hi-Fi

Omul clar cauta ceva de calitate daca a propus un amplificator de 10W.

Pe de alta parte pentru house ,tech,filme si alte comerciale cred ca mai potrivit ar fi un amplificator de calitate ok dar ceva mai puternic un 30-50W

Cu 10 W daca nu ai boxe cu sensibilitate ridicata imediat duci in limitare amplificatorul.

Un amplificator mai bun Yamaha CR-440, e mai hi-fi ,costa 350 ron pe un site de licitatii.

se gasesc si alte alternative mai bune decat un amplituner
