It's been nine months that uses this amp with speaker warfadale vs-15x for now I u is no problem. the amp is small enough (1u) but it is a bit noisy mas very quickly covered by the sound of music. This is the same as it is a boost amp and the power indicator is not very respected, it rises rapidly dan red. I advice for the small group that occurs in a club. I will not go with the choice to experience acute because Criar and made her pregnant with my male in the ears.
