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

Thanks George
It was an avenue I was interested in exploring simply because of the good results I had with the ht rig.
However in retrospect majority of the listening is dialogue and special effects...loud ones!
Not too much finesse needed there, just good muscle which class d certainly has in spades.
Just as another test I actually played some cds through the ht rig and although it sounded ok it is in a much lower league than my stereo rig. But it is oriented towards movies really with a large Martin Logan center and big psb sub for "effects" .

Reasonably priced, I purchased a NewClear NC1000L, class D amplifier.  I've used many different amps in the past..  What I get with my 4ohm Legacy Focus SE speakers, driven by the NC1000L, class D, is very good.  Clean, detailed, with a very good sound stage.  1000 watts into 4 ohms, built in the US.  I have no affiliation with this company, just a satisfied user.  Not expensive, and good. Check the NewClear out.

 
I had an all BAT outfit a while back. VK5 + VK500 w/BAT PK.

thankfully, it was in my office and not in my listening room. yep. the big BAT amp gets hot. very.

A lot of amps do however. Class D has made some immense strides and is a prospect for me with my next system build. I was disappointed to see Bel Canto quit making their top tier 500 wpc amps though.

Glass and Class A will always be heat sources. Period.

for my money, it is worth thinking abuot putting the power side of things, if not all of it, into a separate enclosure, or room and supplying it with cool AC.

whichever way, keep mindful of matching the impeadances between pre & amps, and in the wiring too.
be well, J

Hello, You've already had some great advice so I'll remind you we all have opinions and a lot of great suggestions....
Mine may not be appreciated by many but let me begin with the disclaimer that this is my overlall assessment and thus this is my general experience... in other words I'm not trying to be insulting and there are always exceptions to everything...
So here goes: If your current system DOES include / or matches the description of ANY of the following components then you will very likely find a transition to  Class D (If that's what you'd like to do) to be sonically painless and relatively satisfying to integrate.
*  More than 2 speakers

*  Any "Processor" of any kind including but not limited to DSP that effects anything more than a dedicated woofer amp which must be completely separated from the main signal channels and effects ONLY those frequencies under 200hz or so [but preferably no higher than 40-50hz maximum]. 

* Stock power cables

* "Radio Shack - Equivalent" speaker cables

* Multi channel receivers used as the 2 channel amplification.

* Any form of [video/TV] viewing screen located between the [only 2] main speakers unless completely retractable into an essentially out-of-sight mechanism
and thus completely inconsequential to room acoustics.

* Extraneous/superfluous furniture inhabiting the room forward of the listening chair (and preferably minimized in the room in general).

* Excessive reflective surfaces including windows/ sliding glass doors... and /or excessively overdamped room: heavy pile carpet, thick drapes, etc.

* Wall outlets/ circuits which must share the same lines as major household high current demanding devices such as refrigerators, HVAC systems, etc.

    I could go on. These are just general guidelines. 

On the other hand: If you tend to emphasize simple/ straightforward/ "uncorrupted" and dedicated signal paths..,If you savor seriously well designed relatively minimalistic equipment with a generally sole purpose.. if it's well designed solid state or [my prefence]: vacuum tube based...If you've experimented with a number of different cables..and if you may have taken more hours than you care to admit with exacting set-up procedures dominated mostly just by listening...    There's a very likely chance you will actually hear what the Class D amp is doing. 
    Then you'll be more likely to decipher its influence and judge more deservedly.
   Personally I have yet to hear one I like but your mileage may vary of course. Good luck and happy lissn'n.

  

Um, I think proper room acoustics are important for any setup, 2 channel, 12 channel, tube or digital amps.

I strongly encourage everyone to get that sorted early.

The idea that a well balanced system can't abide a Class D amp is not something I could support. I also could not support the idea that somehow better room acoustics will prove all tubes better than all class-D.

Best,


E
