Sound Quality Vs. Measurements

Prey tell, what's meaningless about it? Quoting a figure, or a range, is meaningless? Saying something like: "I think that under open loop conditions, at full power into 8 Ohms, with zero global feedback, you are fine if your 20-20,000 Hz THD figure is 0.5%, but watch out for the distribution and decay rates of those harmonics."?

Give me a break, SY.

Let me rephrase that - how would you ask the question to make it "meaningful"?

Right. But he did not recognize it in my anology, so we have to start the thread from the beginning. May be some essay based on the thread would help?

See post 6047.

I just did, and it still looks as pointless as it was on first reading.

You see, if I think you said something wrong, I won't just say that you're wrong, I'll try to explain why I think you are wrong.

You speak of wrong assumption - but you specify none. That makes your comment meaningless.

Just repeating that statement will not make it true, and will give it no further wait.

Why remains a mystery, but it's fairly obvious neither you nor Wavebourn are willing and/or able to provide a simple answer to a simple question. Nor are you willing/able to state exactly what are "the wrong assumptions" I have made.

Thankfully, I have other, more communicative people to ask. So forget it.

No, I still don't understand why you asked your question. You know it was oversimplistic, although perhaps Stuart could have been slightly less abrupt in saying so. Unfortunately I am too far away to bang your heads together and tell you to play nicely together.

If I want to run a mile in under six minutes what colour socks should I wear?

Cant we all just get along ...


Sy ... Semantics really, Yes DVV question was a bit scattered , but I'm sure you got the gist of it, well enuff to respond with your dream design open loop low feedback SS topology , well unless you don't want to share ....

So did Anatoliy and Dave, who responded quite properly.

My suggested question still hangs out there, which I think is more relevant to the topic of this thread than is topology.

Apropos of online exchanges lately, there's a lot of rancor afoot. Last night in a chatroom I lost my temper in a way I do of order every five-ten years or so. I received messages outside the room of support, and the moderator kicked the individual who had provoked me --- but it was still "shocking" to me that I was so drawn in.

Odd times.

Yes virtual reality has become .. errr ,ahhh, reality .....

I think one of the weaknesses of the internet is that we can't see each other's faces, so we can't tell whether this is a good time or not to say something which might provoke a response. So we sometimes accidentally annoy each other, and sometimes we do it deliberately in a way we might not face to face. What is more surprising is, as bcarso says, we allow people to provoke us. That has happened to me several times.

I have now started using my ignore list, although only two people in it at present. I don't like doing this, because it suggests I lack self-control.
