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

Ok so I know there are already lots of threads on class D both negative and positive

As I have had a very positive result with replacing the ss amps in my ht rig with a single tiny Nuforce class D amp I was tempted to look into the same for my stereo rig.

This is a little more difficult as my present amp is a BAT VK600SE, 120LB of muscle and heat.

Now I am in love with my present sound but still am very curious if class D could do anything for me as it certainly did in the ht rig although those ss amps were not in the BAT league to start with.

So I would like to hear from people who have actually gone this route, replaced their expensive, heavy, power consuming amps with tiny little cold running boxes and what their results were.

Was it uplifting, about the same or make you wish you had never heard of class D!

Cant say as I have done a study on the heat but after a couple hours of run time even at moderate volume levels it sure is pumping out the heat above it.
That and its 120lb bulk are reasons it sits on its own little amp stand in clear fresh air away from the other electronics!

Y'know....I'd hook up one of those 'puter fans to each one, set up so they come on when they're running.  Pick for low db...and they're cheap...

I do that for my amps and receivers, fan-force air through them.  I do it just to 'keep my cool', so to speak.  You could use it to utilize that heat as well.

I don't even hear them running....

Holy crap, you should be upgrading your speakers then worrying about your amp.  Talk about a mismatch.  

As far as class D goes, I highly highly recommend looking into the NEW Peachtree stuff.  Nova 150 and 300.  Simply amazing.

Class D makes big power at low cost. It is this factor and this factor alone that compells manufacturers to adopt this topology. Yes, some can sound decent but replacing a BAT tube amp?... If your amp is causing you to sweat, you can move onto good Class A/B and not miss much in the way of musicality.
If you can’t tell a difference between Class D and A/B, time for a hearing exam.
