I have the A3's. The best sounding amps I've tried are high amplification SET mono blocks. I'm finally at audio nirvana with NAT Audio Magma M mono blocks.
A buddy has the S7's. He has VAC 450iq Statement mono blocks. He once told me that in order to get Magico right you basically need to spend about double on amplification in relation to the cost of the speakers.
The best Magico sonics I've heard have always been paired with high output tube amplification. I also agree with other audiophiles I've spoken with that 4 ohm speakers need tremendous power coupled with at least moderate volume to sound their best.
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.
