Harry’s Burson V4 Opamp with Audio-gd Compass 2

Published on

Post Info

I was looking for an improvement to my audio-gd compass 2 and my computer (gigabyte z87 sniper z5). Both devices have OPA2134 on it. I made my decision from reading much about previous burson audio op-amp review on the web and take the plunge on this new supreme op-amps series.

The decision is paid off, I like the sounds coming now from both devices. The mid is fuller, voice is clearer and feels more detail coming out from it.
