Kopul HAMP-MATE-B1 Reviews

You can't go wrong with this amp.

I bought three of these amps and they sound magnificent. They easily compete with my Topping A90D and A70 headphone amp. The sound is very resolving and neutral with more than enough power to drive my Beyerdynamic 700x pro loudly.

Great sound
