Short answer: the Monitor Audio Silver 50 8G for better sound quality, the Micca RB42 for the lower price. The Monitor Audio Silver 50 7G ranks higher than the Micca RB42 (#16 vs #154 of 179 bookshelf speakers) but is discontinued. Its replacement, the Monitor Audio Silver 50 8G, is rated 4.2/5 at $1,250; the Micca RB42 is rated 2.3/5 at $159.99, $1,090.01 cheaper.

The Monitor Audio Silver 50 7G is the more accurate option. An award winning compact bookshelf speaker with accurate sound, a gold dome tweeter and good bass weight for its size. Its measured preference score, a predictor of how neutral it sounds, is 5.40 against 4.59 for the Micca RB42. The catch: The on axis response trends noticeably upward toward the treble (rising about 0.5dB per octave, a steep tilt), which can read as bright on already bright recordings.
What the Micca RB42 does well: A budget bookshelf speaker with a curved cabinet that looks far pricier and works with a wide range of amplifiers. Watch for: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite seeming detailed at first.
Buy the Micca RB42 if price matters most. For better sound quality, the Monitor Audio Silver 50 8G, the replacement for the discontinued Monitor Audio Silver 50 7G, is rated higher but costs $1,250.
