O problema é que este sistema custa 450€ (preço novidade) , já traz amplificador/descodificador (não se compara ao pioneer que mencionei é óbvio) e tem 2 colunas wireless (dá muitooooo jeito). Daqui por 2 meses o sistema está nos 350€ seguramente, mas mesmo assim, não sei se não prefiro dar ~500€ pelo sistema da Pioneer, mesmo tendo fios.
O Pioneer sem duvida é muito melhor so a quantidade de formatos que descodifica:
