Best amplification for Magico S3 newer version on your experience

The Luxman 509x is rather weak compared to the Luxman m900u and the new amp (m10?).  I have heard all 3. These Luxman amps are warmer that the other amps I mention later.

The CODA #16 is a great amp and even though it is 150 watts it is incredibly powerful because of the amount of current it generates. They do not come up for sale often. I heard the CH Precision top end amp in Canada last summer. It was over $100k USD. It was a tiny bit cleaner on top over the #16 but it was not an apples-to-apples comparison. I own the #16 and I feel the only thing I will get with an another uber amp is a different sonic presentation. The #16 is a tiny bit warm.

The new SimAudio Moon North Collection is a new fav of mine; I heard them a few days before I heard the CH Precision top amp. This was on a different system. There is a very unique character to this lineup. Very clean, very much like a slightly warmer Benchmark AHB2 but with more balls. The North amps are neutral.

If you want to save some cash and have something that is really good while you save up your pennies. Take a look at the new Schitt Wotan amp at $2k. It takes about 2 months of heavy playing for the top end to settle but I love this amp in my office system. It is not as good as the CODA #16, but I am not replacing it. It drives the difficult Maggies.It is slightly warm.

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. 

FWIW I’ll give you my experience for driving a pair of Magico S5’s. I started out using a Luxman m900u. I thought it sounded great. Then I switched to a Coda S5.5 amp as I’d had the Luxman for a long time and had the itch to change to something new. The little Coda outperformed the Luxman in every way. The Coda is only 50 watts class A into 8 ohms and doubles to 100 watts at 4 ohms and can drive a 2 ohm load at 200 watts. I think the key to its ability to out perform the Luxman is that it draws 100 amperes which a lot more than the Luxman even though the Luxman is 150 watts into 8 ohms and 300 watts into 4 ohms. The little Codo retails for $6,400. I recently saw a used one for sale on either this site or usaudiomart.  That’s just my experience. Good luck!

I've never heard the S3s, but the CAT amps sounded amazing on the S5 MkII
