Ditching Class A Amps due to Heat - Sort of a Poll

I own a pair of Pass XA60.8s which have an idle power dissipation of 400W each. I don't think I'd consider buying an amp that use more power than this at idle. 

My Pass amps have not been in my system for more than nine months since I've been using a pair of 300B PSET amps. These have plenty of power for my system and I like the sound a bit better (although the XA60.8s are very nice). My 300B amps are also class A, but have an idle power dissipation about half of the Pass amps. 

I do have a Purifi class D amp that I use in my bedroom system and it's nice to have extremely low idle power dissipation so that I can just leave the amp on all the time. But, as good as it is, it lags behind my Pass and 300B amps. 

Class A for me.  Two First Watt amps,and a pair of Monarchy Audio mono blocks.  Listening to well reproduced music brings me joy. I like what I like. Oh ya, they run hot. I still love them.  

I have two Class A amps (modded Plinius SA103 and Reference Line Silver Sig) and love ‘em both. But I’m open to this new GaN-FET stuff. A friend is bringing over a Peachtree and the Atma monos in 10 days for a head-to-head against my amps. Should be interesting!

Has anyone successfully used class D amps with 16 ohm rated speakers?

I've tried a few versions of the cheap Sonic Impact amps as well as the Sharp SD-EX111 mini system with such and the sound of the mid's on up is odd/wrong.

Both were fine with 8 ohm rated wide band single drivers I use, as well as with a conventional  2-way 8 ohm speaker.

I balked at purchasing a recently discounted/cheap Class D integrated amp with "room correction" capabilitys because of this, but also because of the software/hardware required to use the "RC".

Anyone else use Class D to run 16 ohm speakers?

Luxman 590AXII.  Replaced a tube preamp/cllass AB amp setup. Dissipates 400w continuous, which is welcome this time of the year, as I get up about 4 hours before my wife, and the house heater doesn't go on until she's up.  Room is nice and cozy.  Summers are mitigated by an efficient ceiling fan.
