I have the MSP3A and you definitely need both of these when mixing because the MSP3A is very digital sounding but the construction of the MSP3A is way better than the HS5 even though HS5 has more low end. I will get the HS3 for faster mixing decisions. You will learn a lot with the MSP3A’s if you’re a mix engineer. Plus they look really nice! Better looking than anything on the market at this price point I feel…
