Class D is affordable and sounds as good or better the SS/Valve why buy anything else ?

I have spent a fair amount of my hard earned money on big ticket brand new SS and VT/Valve amplifiers over the years without hesitation, with state of the art 2019 class D amplifiers becoming cheaper and sounding better, i wouldn't join in again.

For older technology amplifiers SS VT/Valve to compete with State of the art class D, Their prices are going up and up.

One example is Pilium Audio from Greece or Bulgaria their Divine Line the prices are all over £100,000 for their pre amps and power amps, I know the UK importer he said they sound OK,

Another example FM Acoustics again up to and over £100,000 for pre and power amps. i have owned FM Acoustics pre and power again their OK,

I am not saying they do not sound good, i am saying why spend this much when state of the art class D probably sounds as good now and can only improve with the GaN capacitors and is nearly up to 100 times cheaper.

Is there still a market for multi thousand £$s SS or VT/Valve amplifiers ?

When class D finally overtakes SS VT/Valves what will people do with their multi thousand £$ amplifiers, keep them knowing there is something better ? Or will we see the market flood with exotic used amplifiers ?

Digital technology is rapidly growing pace and becoming cheaper, with GaN capacitors being introduced the sound is going to get better and better and will slowly or quickly become even more affordable.

If you had 50,000 to spend on an Amplifier, would you buy a high ticket SS amplifier and hope for the best ?

Would you stay safe and go with high ticket valve amp, class D can never match good valves right ?

Or would you sit tight and see how the GaN capacitors can further improve the performance of state of the art class D ?

Please feel free to join in, everybody is welcome, i think its a very delicate/touchy discussion for some people with big bucks invested in older type amplifiers.

The benefit of class D is better sound quality now and the penitential with GaN Devices to get even better,
To state the benefit of class D is just efficiency makes you sound stupid.

@sthlm78:

Sure you could use a tube input stage. Or a coloured SS input stage like some use. 

@helomech:

I think the fact that for around $1K can get you the level of sound that's only possible from $20K+ class A or A/B amps, also gives them an advantage. Unless cost, weight, and size is no object for you. In that case buy a Soulution 501 and call it a day.

I believe one should read the whole interview of Bruno Putzey to get the full scope of his adaption and belief of "Class D" topology.

There is no such thing as uncolored.  Everything has a sound.  Even one piece of wire 4 inches long has a sound.  Every Class D amp using the same module will have a different sound because everything matters.  When the NC400 amp module came out a few years ago the Objectivists declared it perfect.....measured perfect, so must be great.  I did a mod on them where I changed the polyester output filter caps to modified stacked polypropylene caps.  It sounded much better.  Here is a link to a thread where this is talked about....notice the resistance from those who have not heard it but "know" that this mod cannot make a difference.

So, was the amp "uncolored" before the mod or after it?  Neither...just better sounding.

Mike (Mr. Mivera) has stated that his more expensive versions of his amp with the thicker chassis and better wire and jacks sound better than his less expensive ones.  They will not measure any different.  So, which is "uncolored".  I A/Bed my new prototypes to Mikes amps and his amps sound very "colored" in comparison.   So, does that make my amps "uncolored".......no, just less colored.  There are and will be amps down the road that are even less colored than mine.

I have made a class A amp that has very little color.  However, I do prefer the modded IceEdge.  But, I am rebuilding the class A amp so it will be way, way better.  Will I still prefer the class D?  This game is never ending.  There is no perfect anything.  What you get with the latest tweaked modules is incredible sound for very little money.  Tomorrow, they will be boat anchors.......he he......for a very tiny boat.

Once again Ric, where did you get a pair of my Purepower SE amps to audition? And if you don’t have pictures it didn’t happen.

And do your board hacks void the Icepower warranty? I can't see how you could hack into the input circuit of that multi layer PCB without making a mess of it.
