Es mejor que el amplificador vaya sobrado ante los altavoces?. Como ahora va por rangos el uso adecuado de unos altavoces con respecto al amplificador y dan bastante margen. Por ejemplo:
Dali Z3
Potencia de amplificación recomendada (RMS): 25 - 125 W // Impedancia nominal: 6 ohmios
MA Bronze 2
Potencia de amplificación recomendada (RMS):30 - 100 W // Impedancia nominal: 8 ohmios

yo después de mirar todos calidad-precio, opté por el sr-v685, me lo entregan mañana
