I just went through the same dilemma 3 month ago, but with the Magico S5 MkII speakers. It came down to 2 integrated amps in the end that sounded really good to me within my price range. The Macintosh MA1200, and the Vitus Audio RI-101 MkII Integrated Amplifier. I ended up with the Vitus, and really happy with my choice. Very reveling with a great sound stage, and it is a little on the warm side, but not to much, and it pairs well with Magico speakers. It retails for 21K.
Best amplification for Magico S3 newer version on your experience
I purchased a pair of S3 but now I am facing that I might not have the funds for top brands amplification that I see them pairing at shows CH, Solution, D'agostino
Etc.
I come over here looking for advice.
Currently using Luxman 509x. My room is 18x12 and I listen to low to moderate vol.
Thank you in advance.
