This power amp is inexpensive and high quality. It’s not as loud as some say but you definitely hear it. I use it with two PA speakers and get loud so the fans aren’t a big issue. I use my Eris 5s during tracking and the Gemini and PA after it’s all said and done. It really depends on what you’re gonna use it for.
Sound
Sounds freaking amazing!Make sure you get the Hosa Speakon cables also. Otherwise you won’t be able to plug into the power amp.
