Warm Class D for horns?

Hello to all,

Recently  was researching about the evolution of class d amplifiers, for what I understood the most advances around are the Hypex N Core, ICE, Pascal, and appears that also some manufacturers are developing their own Class D amps, like Spec from japan for example and Devialet from France for example..

I understood this right? This is what is happening?

The whole point of make evolving the Class D amplification is to make they sound more warm?

I'm panning to build a 3 way loudspeakers, radial horn, super horn tweeter, and woofer, at first I was considering just use Class D for the 12" woofer, but what about Class D amp for the horns and super tweeter, anyone using?

Let's talk about this, would like to know more how Class D evolved over the years and who are the manufacturers that are on the vanguard fo design of this amplification topology...

Oh.. Class D analog, Class D digital... never found a consensus, if Class D can be analog to..

Thanks!

I have a Fosi bluetooth Class D amp I use in a small A/V system that cost $85.  It's outright amazing within its limits.   Its the size of a pack of cigarettes and ~ 40w/ch.  My  Boston  A40s never sounded better.  Is the sound a touch "warm"? Perhaps.  It uses a Texas Instruments Class D module.

I recently picked up a pair of Vanatoo powered speakers.   Each has two Class D amps built it, one for woof and one for tweet.   Don't know much about the company that makes the amp circuit.  I heard them at Capital Audio Fest last couple years, was impressed and finally picked up a pair.

I have a Wyred 4 Sound ST-1000 MKII (460 wpc, ICE power) driving Klipsch KLF-30 speakers and it's a nice match. The mids and highs are detailed, but not shouty or bright like they can be when paired with the wrong amps and bass control is excellent.

I recommend the ICEPower module based amps.

I found them quite warm, comparable to the Parasound A21/A23
Best,

I have never heard a warm class D amp. Cold and sterile comes to mind.

Only some of Audio Research's early class D amplifiers are not still serviceable, to correct something stated above.  At least according to ARC's site list of unserviceable models.

I own Audio Research class D DSI200 integrated and I love it and find it to be quite warm and tube-like sounding.  That's how they voiced it, to sound like their tube amps.  And interviews with their lead designer as ell as reviews (to extend you put any stock in those) at time of release 2010-ish make clear they considered it very successful in meeting that goal.

There've been a lot of developments in last 10 yrs, but I don't think I'd trade my ARC for another class D today.  But that's just me.
