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!

I don't see Ncore on your list but Rowland uses NC1200 amplifier modules in its upper end amps and BelCanto also uses Ncore - custom modules in the Black, and Ncore NC500 modules in the REF 600M, which has received all the rave reviews.  Acoustic Imagery offers a bare-bones pair of NC500 monoblocks for $2K - for the pair.
Between Rowland, Bel Canto and D-Sonic, you certainly have the price range covered.

I wish you all the luck iberwaltz.  I tried to get rid of my VTL space heaters a few years back. I used Classe and Bryston for a few months each and always went back to those room heating tubes. I gave up and later upgraded in the VTL line.

Ones I had considered so far include Bel Canto, Jeff Rowland, NuForce, D-Sonic
Out of that lot the BC600mono’s were the ones that has the best Class-D sound I’ve heard, but it needed to be driving a very flat benign 4ohm, from mids to highs to get that sound, otherwise it sounded fair, this was achieved with a very expensive Raven tweeter’ed 2 way. "Could" also work with Maggies.

It always amuses me that in the whole 'to D or not to D' discussion that the simplest answer to 'will I like it (the sound) or not' that it never occurs to anyone to simply 'cheap out' with a simple test....

Buy an inexpensive unit.  Flog the daylights out of it, like I did.  Find out for yourself if it's worth going further with it.

For sure, an inexpensive unit won't be as 'nuanced' as a more expensive one, but at least one would have the opportunity to stick your toe into the water before you cannonball in....

Just my 2 cents of (perhaps) sense...;)

Personally, I like them.  But I like all types of amps.  Viva la difference. *S*

The key factor is that class D is physically, mathematically inferior to class A-A/B.

That's not to say you can't accept the inferiority for the sake of something you value over absolute sound quality.
