Wilson has much more bass weight than Magico. Magico sounds quite light compared to Wilson. Those who prefer Magico over Wilson in bass will find Magico's bass cleaner and faster and more detailed, and Wilson's muddier.
Magico disappear more easily than Wilson in a room. They are more coherent than Wilsons. In Wilson, once you go over Sasha 2, coherence becomes a challenge. They sound like separate speakers, you can hear the instruments through in separate sections.
Wilson is warmer than Magico. It is also more colored than Magico, though I also find Magico tonally grey. It has more density than Magico. Magico sounds more detailed than wilson.
If you listen to a Wilson room, the overall feeling will be off a larger sound, more density, warmth, weight. If you go to Magico room overall feeling will be cleaner, faster, more transparent and coherent, less room interaction. Those who prefer Wilson will find Magico colder. I have no real preference for one over the other. I find both not natural in tone and timbre, and they project sound to create artificial soundstages. I find them both quite slow though Magico is faster than Wilson
The advantages of bass weight in Wilson is best felt using an amp like Dagostino. Using valves reduces this but adds decay which for me becomes too much colour. Those who like Wilson with valves seem more focused on midrange, but then I wonder why they simply don't buy Martin Logans. Many who buy Wilson get taken in by the bass, which I feel is a non-natural artefact designed to impress at shows. I remember one of the manufacturers of a competing cone telling me he wanted to make the next flagship to compete with Alexandria on bass. He really respected Alexandria's level of bass, and felt he was losing customers on that front though his speaker had better coherence and tone.
YG - I prefer YG to both, though some online discussions seem to suggest people finding similarities with both YG and Magico. I have no idea why, except they listen to YG at shows. YG is on Magico side of neutral rather than Wilson, and disappears easily as well. It feels more like an electrostat and has better decay than Magico and I find it more musical. At least at Hailey level, the bass is lighter than Magico and I feel subs are required.
Actually, Avalon if well set up has very good coherence through the drivers, very good bass, and timbre. Very natural. and disappears well. But requires a lot of room. In cones, B&W D3 series also has good weight, one that I like. Zellaton has possibly the best midrange, like a ribbon planar, at least when heard with FM. Stenheim is similar size to Magico with more bass and soundstage and efficiency.
