Best amplification for Magico S3 newer version on your experience

I imagine your Magico dealer has multiple amps comparable to the CH, Solution, etc. level amps and would be tickled to death to lend you one which would allow you to compare them to your very-capable Luxman. 
My guess is that your Luxman will do extremely well when compared to those 5 figure amplifiers.  Please let us all know your experience!

You could also try the Anthem P2 amplifier for around 5k

It has plenty of power and will easily go down to 1 ohm

I have heard Magico with less than top of the line audiophile electronics and they sound terrible to my ear. The Magico are so detailed and fast that any imperfection in the signal path will get amplified. You want to be using top of the line electronics that are of your musical inclination. VTL, Audio Research, Boulder, Burmeister… this level.

As my friend used to say,"You need an amp you can't pick up"  Pass Labs, Ayre, Boulder are a few.  Atmosphere make a hybrid that got good reviews.  Not sure their tube amps are big enough, but i just saw a used one for sale.  I thought tube amps dont like low impedence.  Maybe money solves that.I don't know why high end speaker designers make speakers with such nasty impedence.  Lots of them.  I will keep my horns.

I recommend you do a home demo of Classe Delta Monos only if you are 100% sure that your cabling is not your bottleneck.  Alot of people will tell you that cables and amps don’t matter but they absolutely do when you are building a system of your caliber.  Now I do not believe in cable burn in as every cable that I’ve added through my upgrade path, I’ve heard an immediate difference.

Back to the Classe Delta Monos - My previous amps were the Parasound A21, Audio Ref 75 and 150SE.  I still run a Ref 6 and Ph7 in the pre but with 600 watts in 4 ohms it really pushes my system.

Michi M8s as mentioned do not have the finesse on the top end like the Delta Monos and are more bass heavy.  I got off the tube power amps wagon because I was racking up to many hours on tubes and the replacement cost is not worth it in my opinion with the cost of power amp tubes these days.

The other solid state amps mentioned are all very nice but more than double the cost of the Delta monos for only marginal gains.
