Short answer: the Edifier S1000MKII. It ranks #82 of 108 powered bookshelf speakers by sound quality (rated 3.3/5) at $499.99 and is still sold new; the Midiplus MI5 II ranks #97 (rated 3.0/5) and is discontinued, so it is only an option used. The Midiplus MI5 II’s replacement, the Midiplus MI5 II V2, is rated 3.1/5 at $169.
Why pick the Edifier S1000MKII: A self-powered stereo pair with optical, coaxial, analog and Bluetooth inputs that makes switching sources simple. The catch: High-resolution input support is not a guarantee of perfect tuning, and the fixed internal amplification prevents the gradual upgrades possible with separates.
What the Midiplus MI5 II does well: An inexpensive powered monitor pair with balanced inputs, Bluetooth and fairly deep bass for the size. It keeps a wired aux input, which the Edifier S1000MKII lacks. The tradeoff: The 2.24 standalone and 4.53 ideal-subwoofer scores show significant problems above the bass region.
Buy the Edifier S1000MKII. It is rated higher for sound quality; the Midiplus MI5 II is no longer sold new.
