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

I have heard both.

I was on a similar quest earlier this year (see my post) asking a similar question. I was looking to run them on Devore O/96

I heard the Air Tight ATM-300R on a 87dB speaker (I don't know what the dealer was thinking while setting it up!!!) and the MQ-300 on a 90ish dB Triangle speaker.

Both on completely different systems so hard to compare. 

But I loved the MQ-300, it is by far the best amp I have heard. Although I agree that you should look for higher powered amps, both of these amps might drive your speakers. 

I wish I had heard the ATM-300R on a more efficient speaker to get a proper handle on its capabilities, but the fact that it drove an 87dB speaker was in itself a feat.

Definitely get the MQ-300, then someday upgrade to the Orangutans ;)

Thank you for your update and confirming my suspicions that the MQ-300 is one of the best out there.

Yes, the build quality is quite out of this world. Pictures do not do it any justice.

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

Please do let me know if you ever get a chance to audition the Engstrom Arne. Would love to hear your opinion of it vs the MQ-300.

I found it better than MQ-300 in some respects but the MQ-300 to be a better all round performer.

But the catch was that the Arne I auditioned was not broken in. It was brand new from the box, perhaps that's why it wasn't as relaxed as the Luxman. But I don't know.

No need to test. Just listen at the store, if you are free sometime, would love to know what you think.
