Short answer: the KEF LS50 Meta. It ranks #4 of 179 bookshelf speakers by sound quality (rated 4.5/5); the Aalto Speakers Aalto 1 EVO ranks #11 (rated 4.3/5).
What the KEF LS50 Meta does well: An iconic compact KEF speaker with highly accurate sound, pinpoint imaging and a coaxial driver that keeps tone even across the room. Watch for: F3 of 67Hz and F10 of 42Hz mean it doesn’t get much below 50Hz in-room; a subwoofer is recommended for real bass.
What the Aalto Speakers Aalto 1 EVO does well: A very compact Finnish bookshelf speaker with excellent, neutral sound and a waveguided tweeter at a budget price. The catch: Low 81.5dB sensitivity and a 3.3-ohm minimum impedance demand a capable amplifier.
