    I’m impressed with this amp, paired it with my set of SA 6.5sw’s and they play fantastically, would certainly buy again

    It sounds better then I could have ever imagined. I applaud your service and the performance of this amplifier.. I had doubts because of how small it is. But let me tell you your reviews are everything and more I couldn't be any happier. Thank you for your product
