Luxman 509x or Simaudio 600iV2 with mágico A3.

If people only knew how good A3 with 509x.

I have had several sound systems twice three times the price.

I just love this.

I haven't heard Luxman and Moon with Magico - though I have listened to them through Wilson.

I've been impressed with both.  My perception is Luxman has slight warmth compared to Moon.  

If I was you, I'd try to get an in home trial because I think the differences are preferences not quality and reliability.

Both amps are excellent.

You are right the 509x fil the drivers with a wider stage.

Moon still musical and warm but with a more dead background and more information.

Both amps work great now it is a matter of personal preference that I need a few hours of audition.

the krell or coda gear are both ideal the

Magicos benefit from a warm amplifier,

the coda csib sounded better then the Luxman and Hegel we had all three some years back the csib had the widest soundstage of the three.
