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

Oh yeah,   the BAT you have  is a beast.  great  amp and certainly can be fun at times.   I wouldn't be able to run it though like all the time.   .   best thing is switching off  from the smelter   to other amps at times so as not to heat up the house on a summer day.   Thats what I have to do - take a break from the Pass and the BAT probably is warmer.        

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.  

Been there --  the  simple answer at least for me is  --- Ive wound up relegating  the class d for duty in hot weather.     I wouldn't be in a hurry to sell your BAT although that sounds like a bit of heavy weight and likely equivalent good listening could be had with an amp that weighs half as much or so.    I would have to see what model that it is and if its  tube ,  in my experience,   that Class D will not be as satisfying as the tube or  s/s  class A or A/B amp..   Its a different sound and has it place  and can sound good-- It obviously works wonders as a lot of people go with the class d as main amp.... To me I just seem to get a little more from conventional amplification topologies.     I like to mix em up.   tube amp,  class a/b amps,  class A amp (Pass)    and a Trends for the hot weather-- all used among 2 systems.   A good buy available in the classifieds right now is the PS Audio---HCA 2  or something like that.   Lot of raves on that amp..  Good way to check out class D .   Have fun.  

Its not surprising that W4S are  good listening.   They were Cullen in their previous iteration and were making the class D amps for PSA back then.. The internals I suspect and I don't know more that that-- If I recall correctly.        Class D   can excel depending on system synergy... just like any other setup.    And a credit to its capability and sonic  virtue--Im using a diminutive  $180 Trends class D without readily discernible dysfunction.  Certainly would have to A/B with another amp to perceive the difference  and  those I have here all cost much more as well.
