Luxman 590axii ventilation

Hello,
The answer is no. Here is the user manual:

At the beginning they give a warning of poor ventilation. They do not give the exact measurements. If you do a little scale math it looks like 4” on all sides is the amount you need. Even if you turn it in and listen for an hour you are probably destroying those capacitors. 

There’s a Luxman tech in the U.S. you can call for the advice you’re needing. I spoke to someone named Jeff at Luxman’s Technical Assistance number, 781-608-1044, on the same subject a couple of years ago.

At the time I was constructing built-in cabinets for my equipment and needed to know how much open space to provide around a Luxman L-507uX Mk2 integrated amp. Not a Class A, but still ended up requiring a substantial amount of space over, to the sides, and behind it. Approximating his recommendations I now have 11-1/2 inches of space on either side of the amp, 6-1/2 inches of free space above it and the same 6-1/2 inches behind it. That’s worked out well, so I’m guessing he could accurately provide you the advice you need for a 590AXII.

Don't see ventilation holes will help if the centre channel speaker sits directly on the shelf.

??Rig an open frame to support the speaker and raise it a couple of inches more.

Really appreciate all the comments here. I’m kinda stuck with the cabinet and shelf per negotiations with the wife as it’s in the living room. I can get to 4” of clearance above, 3” on each side, open in the back and front. Thinking I’ll pickup the 509x instead and run a fan in the back as last resort if it’s running hot. Sounds like consensus is that’ll work. 

Call the Luxman tech first and confirm that will work before voiding your warranty and possibly damaging an expensive piece of equipment. I was surprised my Luxman 507uX required so much space around it. First time the fan breaks down or you forget to turn the amp off at night you might produce more excess heat than you expect.
