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

I deleted my own threads on AC. I decided I was done with supporting an admin who would bend the rules for some and not others. If you read the Alexa stats, the value of Audiocircle went up by $40000 within a month after I opened my circle. After I left it went down $60000 in value within 3 months. I was putting around an extra $2000 a month in advertising income in the pocket of the admin, and he still made the choice to bend the rules for the trolls. So I wiped out my content, because I didn't want him to continue profiting off of my time and energy I put in. 

And sorry Ric I’m certainly not jealous of your hacked, warranty voiding science project. I’ve moved on from the 1200AS and have left the modules for all you wolves to fight over. My next project will be far superior, and much much more difficult for you guys to copy. So good luck! :)

So can we just leave it at that?  At least until your "next project" is available to listen to?  There is no real need for you to post anymore about amps that don't even exist.

Refer to the discussion, as a class D lover, I don’t have any knowledge to engage in technical facts! But give me some names in class A or A/B  that produce same amount of power as middle range class D amps in the same price range !

IME, the power of class D amps has always sounded weaker than lesser- specified class A and AB amps. This was also the case in the mobile audio world. One of my first jobs out of high school was installing mobile audio systems. We always had to turn the gain way up on any class D amps to get them to sound anywhere near as powerful as a similar-spec AB amp. Even then, the sound was nearly always thin in comparison.

It's funny (or maybe it's sad), even two decades ago, the manufacturers of those class D amps made similar claims to some in this thread - that their amps had finally broken the class D mold. However, all of us on the installer side quickly realized it was all puff. I worked for a large shop with multiple techs and not a single one chose class D for their own vehicles. We'd only sell them if the customer insisted on a small amp and/or had a very limited budget. Unlike the current home audio market, the cost savings of manufacturing cheap chip amps was mostly passed along to the end-user in that industry. 

A little over a year ago, I compared a Parasound H-int (240 watts/ch into 4 ohms) with a dealer's Devialet monoblocks that were rated at something over 1000 watts/channel. This was driving a pair of Maggie 1.7s to rather high SPLs. The Devialets, despite being some of the best class D I've encountered, sounded less ballsy than the Parasound.

When I owned the 350 watts/ch Rogue Pharaoh (Hypex UCD/ tube hybrid) it sounded much less powerful than my 85watts/ch Yamaha. And as previously mentioned, the Yamaha blew it away in terms of bass extension - by what sounded like a whole octave. 

This is a pattern I've noticed for at least 2 decades now. For whatever the reason, watt for watt, class D power sounds weaker in real use. It reminds me of how Japanese horsepower is often cited in car mags as feeling weaker than German power (well, that's one's easy to figure - it's really a difference in torque).

I have no personal beef with the topology. I truly hope that it will someday surpass the others in SQ, as I'm all about saving energy where practical. Unfortunately, all the ones I've encountered that a mere mortal can afford were still a long way off.

Attention all class D fans! The opposition has an extremely weak case wouldn't you say??

Yet you won't address the fact that Bruno Putzey, who created NCore - regarded as one of the very best class D designs, stated that the only advantage of the topology is efficiency. He even emphasizes that notion by saying, "I can't repeat that often enough."

Read it a second time if necessary.
Seems to me that making a good-sounding class D amp is analogous to taking a dump truck and trying to make it handle like a Porsche. Me, I'd rather just get the Porsche in the first place.

I guess you don’t understand that with efficiency comes a plethora of other advantages:

1: Size
2: Cost
3: lower energy consumption
4: Lower heat
5: Less EMI (conducted and radiated)


And due to the above advantages, possibilities open up the simply aren’t possible with conventional class A amps. Such as

1: Tight integration with DSP and DAC on same board to eliminate extensive sound quality losses from outboard DAC’s, cables, connections, preamps, buffer stages, output stages etc.

2: We can now fit absolute SOTA cool running DSP/DAC/Amp combos right in speakers to eliminate passive crossovers and speaker cables. The amp DSP can be custom tuned for each driver individually, to optimize for distortion, over-excursion, and saturation.

3: We can eliminate having to have separate enclosures for each component. And the costs involved with paying for multiple enclosures. While at the same time drastically shortening the signal path, and optimizing each sub-section to work together in absolute harmony.

The list goes on but that’s a good start.
