Anyone experienced the Luxman MQ-300 or/and The Air Tight ATM-300R?

Best to audition both amps before purchase. 8 watts/ch is only going to go so far...and that is assuming that your speaker even has a mild impedance character across the board! 
Friend of mine has so called 'efficient' speakers--rated at 95db...yet these same monsters drop down to a 1 ohm load in the bass. So, he was surprised that the system sounded thin and a little veiled...
Just like JVS of Stereophile fame who was surprised at the results he ineptly got when he matched the Jadis JA200Mk2 amps up with his original Wilson Alexia's...duh!

Sorry I saw your question just now.

I went with the Nagra 300p that I found at a very attractive price in the used market.

I still believe the Luxman MQ-300 to be a far better sounding amp, but I wanted to see what a 20W push-pull would do for my system compared to a 8W SET (I have one already, so can compare).

But while auditioning in NYC I came across an integrated amp that I believe would be my endgame amp, which is what I am saving up for, want to get it sometime later this year. It did things to my music that I never heard an amp do. The Engstrom Arne.

I first read about it in the audioexotics forum, and after  listening to it I understood what those guys in that forum meant by the term "super high-end".

I have never heard of it but just googled it.
i am sure it sounds fantastic. Where have you demoed it?

I demoed it at Innovation Audio in NYC. The owner (I think) Elliot is a great guy and fantastic host and a knowledgeable audiophile.
