How close to the real thing?

Actually, I don't remember anyone saying that an entire recording sounded real and, if so, based on my own experience (and it has been a few years ((as Mr. Ayer points out)) since I worked in the loudspeaker shop that made the loudspeakers for Bob Katz, after all) I have never heard any system EVER that comes CLOSE to making an entire recording sound real and, when I posed this same question to a few members at the last BAS meeting they were in agreement with me that they didn't think that it was possible to fool someone in to believing that an entire piece was real with today's technology.

As to playing 1 billion notes I simply took the conductor at his word without bothering to check his math.

Atmasphere,

The problem here is that while theorem is supposed, there are real-world phenomena that do not care about the theorem.

I'm sorry, I don't quite follow. Yes, if you use Spice, say, to examine behaviour just based on straightforward theory, it will most certainly not match what really happens. However, if you add in ALL the actual parasitic behaviours of the components, the "real-world phenomena" you mention, into the Spice model then there should be very good agreement between the model (theory) and reality. After all, one of the classic nonsenses of a typical Spice circuit are the perfect voltage sources stuck where needed -- that alone guarantees that the match can be very poor.

In volume three, page 26 Crowhurst ...

Sorry, had a quick look, as far as I can see he is just saying, be careful with negative feedback, otherwise it becomes positive feedback and you have an oscillator -- straightforward stuff.

Fredseas2,

You banged the one note on my kids' upright piano and then compared it to a recording of a concert grand, as I remember. I agree with you that that one note did not sound identical to any one of the many notes in the recording. It wasn't even really close. But the recording certainly resembled the sound of a piano, and it wasn't a particularly good recording and it certainly was not one of the "best" systems available.

At this past RMAF I heard a live piano recital in the hotel lobby and then heard Ray Kimber's incredible four channel system play one of his IsoMic? recordings of a piano. Not identical, but boy were they similar to my ears.

Well, Edseas2, I'm so glad that your view settles everything, after all! And of course, you have the BAS to back you up. And to think we've created a thread five pages long discussing a conclusion we could have just asked you for. :)

Merry Christmas, Ed.

Merry Christmas everyone, enjoy your families, see you back in the threads... Tim
