Amplifier heat...help!

Hi all, 

Working on a system for a small 9 by 11 listening room.   I have narrowed it down to two small speakers: Falcon Acoustics Ls3/5a (15 ohm, 83 db) or the Airtight AL-05, also called Bonsai II (4 ohm 89 fb).

Tha amplifier will go in a cabinet.  I have about 14 inches between shelves and I always play music with the doors open.  I would love to use a tube amplifier but worry about heat.  So I am wondering if readers think something like a Line Magnetic 211ia could work in this configuration, or if it produces too much heat?   I have also been thinking about the tube -like  solid state Sugden A21Se, but have a similar question about its temperature.   Another cool (literally cool) option would be the Vinnie Rossi LIO, an amp I love but that is conisiderably more money.

Are there other options for relatively  compact tube amps (i.e.: . I have 17 inches of depth inside this cabinet including power cords so unit cannot be more than 14 inches deep) that do not produce a lot of heat (relatively speaking?).  Or is there really no tube amp that would work well in this scenario?

thanks!

Double click on my avatar and you'll see an enlarged picture of my equipment rack. The ARC REF-75 is on the bottom shelf. I just measured the clearance. There is exactly two inches of clearance between the top of the KT-150 power tubes and the bottom of the shelf that resides over the amp. Granted, the shelving is an open design, but there has never been a problem with overheating in the many years I've had this rack.  Prior to the REF-75, I had an ARC Classic 60 in its place. No problem there either. The Classic 60 has a fan, but I kept it disconnected for lower noise. The REF-75 has  no fan.

OP
More to discover
