Thinking of replacing my Bat spaceheater with class D, real world thoughts please

I forgot to mention--- I had the PS Audio GCA-100  class D amp that came out after the HCA-2.   GCA is a  great sounding amp as well... The HCA-2 had quite a following though and many preferred that earlier version.  

Yes the BAT certainly is a very efficient heater for sure...lol
However I have to say that since starting this thread I have made a few changes that have left me in quite the sonic nirvana for now,
New speaker cables, wooden blocks under the speakers, very carefull setup of speaker position and angles and swapping the sub with the one that was in my ht rig so now is a REL Stentor which is a very musical 10 inch 500w sub.
All this has mightly improved the imaging, soundstage and tightened up the low bass no end
For now I am doing what we all should
Enjoying the music
Class D adventures are on hold right now...lol

hi,
look into NordAcoustics cheltenham in the UK , they are the best class D available on the market right now, they replaced a pair of krell fpb 450mcx and my krell fpb 600mc, more details musical everything even dare i say it better bass. Emporium hifi in the UK sells them all around the world you will nor regret it, the very top monos i got are under 2k good luck.

Class d wonderful no heat no good sound try Pass used much better.

When I owned my first two Clayton Class A amps (M200 and M300) I used to believe I needed to leave them turned on most of the time so they would sound their best, in spite of the heat and energy usage.  This time around with my upgraded M300, I am more relaxed about turning them on only when I am ready to listen.  Sure, they sound better and better throughout the approximately 30-40 minute warm-up period and sure, maybe they sound another 3-5 percent better if they are left on for longer periods of time, but they sound so much better than the really good Class AB amps I have owned and so much more satisfying than the NC1200 amps I owned, that I can enjoy them from the minute I turn them on.  Basically, I am saying don't worry about the heat - if you like the sound of your BAT amp you may find the sonic trade-off is not worth switching to a smaller, cooler-running Class D amp.  If you want to try Class D, decide which amps you would like to try, and obtain loaners so you can compare them head to head with your BAT.
