Switched to Class D or get left behind?

You shouldn't be so quick to be dismissive. It also seems to be audiophiles are the only ones who are prone to product d elusions. So many get a kick out of being anti-audiophile in attitude.. Not saying this is you.

Everyone needs to consider people listen differently. I've honestly have gone to a friend's house who is an audiophile and his system was in mono without him realizing it. It took me only a couple seconds and brought it to his attention. Another fallacy is listening being equated to hearing acuity. Perfect hearing will not allow one to hear the differences in gear or cables or whatever. This takes experience and learning what to listen for. It also helps if you use a system you are familiar with. Some who have had systems for years may still never get it. You have to listen intently enough to pick up on nuances. There are different depths to which we listen. If someone doesn't listen with depth or intensity they may never get it. I think that's why some don't understand claims that are made by others. If they can't hear it, it must not be true.

It's simple for me there are aspects I hear in my amplifier that no Class D so far has delivered. I am the type of person that just sits and listens though, no browsing phone or whatever, no other side distractions.

AJ is a joker, jester, if that story is even true I'm confident I wouldn't have been fooled.

I didn’t intend to be dismissive. Everyone likes something different and while I have not chosen to go to class de route, I have heard class D amplifiers that I thought were very pleasing.

You brought up a great point

It's not that many CAN'T hear the difference (yet are quick to put down those who CAN and always claim its some bias), it's that they haven't been taught HOW to listen and WHAT to listen for.

I've been very fortunate to have several well regarded friends in the the recording industry teach me how and what to listen for and how to remove pre-conceived biases. Yes you still need to remain vigilant about it - but just because some people aren't able doesn't mean everyone is unable.

And let's be honest, you can make a poll or a study look any way you'd like - look at how many studies claim milk is good for you, then it's bad for you, then another study claims it's good,

I should also say that I never question what someone says they heard or didn’t hear because how would I know? Sometimes the more interesting question is why we perceive what we perceive. I changed out a couple of cables not long ago and I certainly perceived an improvement. If someone asked me if that could be attributable at least in part to the placebo effect my honest answer would have to be I don’t have any idea. I know I am subject to the same sort of implicit bias that pertains to the human race and short of an objective measurement or a blind test I can only say what I perceived, not why.
Unlike the objectivist camp, I’m OK with that because to me it’s listening to music and it’s fun. I don’t make a science project out of it. But everyone finds their enjoyment in their own way.

I was always on a budget I was hoping not to hear a difference in order not to spend money, LOL. I figure if I hear enough difference to get me to spend money it must be real. I also take the piece out and ask if I can be happy without it.

If you enjoy Class D that's fine. You are in good company. I'm just tired of the over marketing and attitude of some regarding the topology.

That's the key - to have someone lead you. The first time I sat with Bernie Grundman mastering an album, he poked buttons and pushed sliders and things got better and better. I had thought that I was a good listener, having horned my craft over hundreds and thousands of hours designing loudspeakers.

But until then, I hadn't realized how much of what I heard can be quantified and qualified. I struggled to hear very change that Bernie made. And when he noticed the pained expression on my face, on the next track, he explained every change, and let me A/B every change that he made. Most of the changes I had to strain to hear the difference. Over a few mastering sessions, I had become a very much better listener.

Scientists have shown that:

1. Temporal acuity of human hearing beats Fourier uncertainty principle:

2. Threshold of hearing is close to quantum noise and uncertainty principle (did I hear that or didn't I ???)

So, I ask myself everyday - what are the things I can hear but still have difficulty quantifying and don't even know what to measure, set alone how to measure it.

Hi Gary,
If you claim you can outrun Usain Bolt, you don't need to measure anything, just demonstrate it on a track.
If you claim you can "hear" class D vs A, AB etc, you don't have to measure a thing, just demonstrate it. How that's done, is by not using your eyes, volume, priori knowledge etc, but rather "trust your ears, just listen". Which, unbeknown to audiophiles, by definition, is a controlled blind listening test.
Now if you must see, know, believe, read, be lead, mismatch volumes etc to "hear" something, well, here we are ;-).
In the end, when, not if, audiophiles fail to hear any difference between D and A/AB (SS not tubes), there will still be the visible, knowledge etc factor that will cause psychogenic drama, ergo...buy whatever pleases one most, in fully sighted and uncontrolled "listening". Pretty simple concept really.
