A brand is not universally better than another. That much should be obvious. Magico's have very high end speakers, yes. But while they play primarily in that ball park, the A3's are $10K speakers that compete in a very competitive price range. That is where is becomes subjective. Not to say that the Magico A3's aren't great speakers - they are. But to my ears, they aren't leagues above their $10K price range competitors. Not by a long shot.
Agreed; It has been ~ 1 year since I sold my Magico S1s to purchase Spendor D9s and I'm very happy with the D9s and ultimately enjoy listening to my music more with the D9s. I had both speakers in my home system at the same time before deciding to go with the D9s. Plus, my system had been 'tuned' to mate well with the slightly cool and ruthlessly revealing Magicos (e.g. Pass Labs 250.8 + SimAudio 380DSD DAC; both are a little warm and super musical).
I spent 3 enjoyable years with the Magicos and do not regret owning them at all. To my ears the S1s offer some advantages over the D9s, and visa versa. Over all though, I much prefer listening to my favorite tunes on the D9s. @freesole, enjoy your D9s !!
