Mackie MR524

I got these for my office to listen to music and some occasional gaming, and it has been a joy.
They sound great both on low and high volume. Surprisingly clear and powerful sound for such small speakers.
I would recommend that you use BALANCED cables with them. I was experiencing some digital distortion from my computer while using unbalanced cables from my Focusrite Scarlett, but it was completely resolved by replacing it with balanced once.

I have this pair of monitors for 6 months and I am absolutely happy with the choice.
I use them for everyday listening, but unfortunately without a sound card. So my feedback cannot be really fairly considered.

Even though I did not have a chance to compare this pair with Persons Eris E5, I enjoy the quality and clearness of the sound and how balanced is the sound (middle and high frequency range, the stage width and pleasant depth of voice) for my taste (I am owner of Audio-Technica ATH-M50 and Trinity Audio Phantom Master headphones). Besides, they are quite light and do not produce a lot of noise while in stand-by mode. The maximum volume (the source is MacBook Pro) is more than enough for a room of 20 m2 or a bit bigger.

I am not sure what can I tell about disadvantages. The two things are missing, but do not related to the monitors themselves - sound card and subwoofer, as there is an obvious lack of low base range.

I like the monitors with their balanced sound and volume capacity, but think that sound card and a subwoofer is still needed for better experience.
