Re: Whom to believe?
hi eric..
i did not say high slew rates are necessary.....
i find it disappointing that you should suggest that i did...
...
Fred has his own agenda in deliberately misrepresenting me....
read through my posts and you'll find i actually agreed with hugh in respect of excessive slew rates being unnesessary...so...whats the beef?
Hugh i am sure you would agree that.....i did not say load stability is unimportant......disappointing.....surprising....

Mikek,
You are so quickly antagonized; please be tolerant and patient.
I was not in the least concerned about your posts; you have not upset me at all as I was a teacher in a past life and enjoy being challenged, particularly if it shows I am wrong and might learn something.
But your willingness to enjoin abuse with Fred, who is clearly extremely knowledgable and knows all sorts of things I don't, is not flattering to your cause. I notice he is not responding at present; a wise, mature move. What does it matter if someone disagrees with you? Who cares anyway? How world shattering are these opinions we all have? Do they add significantly to the body of knowledge in this technology? Probably not....... And what good does abuse do? Abuse quickly denies you membership of any group, even amongst those who would ordinarily support you, and serves no purpose except to highlight isolation. It seems to me that digital duelling is a bit like road rage; pretty safe, wholely ugly, and utterly unfulfilling.
I really was making no comment about your comments concerning amplifier stability. I am aware you understand it to be a significant quality of audio amplifiers; I was endeavouring to explain to any reader here present why stability was important. I was NOT highlighting any comment you had made. I am conscious that you have strong insights, and wish to keep this discussion cool and academic; to be frank I do not understand the math of shelving filters, don't even know what a bloody shelving filter is (I am not an engineer, sadly, having only qualifications Science and Business Info Tech), but tend to assess all amp circuits on the basis of my experience at design, tinkering, testing, listening, and my intuition at circuit analysis, unaided by PSpice or too much math. Oh, I certainly understand all the routine math of Ohm, Kirchoff, and the reactance formulae, even a little on phase margin and Bode-Nyquist, but I'm no mathematician and would argue strongly that all the math in the world can be deceptive in matters of stability, particularly when there is such a diversity of different speakers out there, all with their own reactance peculiarities.
Now, let's get back to electronics. I was enjoying this!
Cheers,
Hugh

I Agree With Phred, Hugh And Capslock
Mike, I must say that I consider that some (far too many) of your posts are indeed straight out arrogantly rude, and intentionally offensive, and as such, totally against the spirit of this forum.
This mode of communication may be acceptable on other forums, but not here on DIYaudio.
You are conspicuously new around here, and it is clear that you have not allowed yourself time to settle quietly into this forum, and learn of the experience of the elder members present.
I solemnly suggest that you adopt the spirit of this forum, or else find a different vehicle to display the brashness, immaturity and lack of social etiquette as you have displayed here.
Phred's comments were in response to your distinct lack of reply when asked politely TWICE of your constructional experience - IOW it is to be assumed on available facts that you do not have valid constructional experience.
I have politely asked you TWICE as to the meaning of the gibberish on your profile page and TWICE recieved from you impertinantly rude replies.
Threads have a habit of evolving and just because a subject like load stability is raised does not mean that this is to be taken as a slight on you, your character or your knowledge.
It would be much better on your part to quietly listen, add constructive comment as appropriate and add to the sum of knowledge presented than to protest as you have done here much more than once.
I take it that in future you heed these words, and become a rather more sociable and worthwhile contributor to this little community.
An apology to Phred for your actions would be very much in order also, and required in my opinion.
As part of this process, an honest translation of your profile, and a summary of your study and constructional experience would likely improve your current standing significantly.
Sincerely, Eric.

Fred's full name is Fred Dieckmann - you have been corrected on this previously, and you have very consciously misspelled Fred's surname more than once since.
This is entirely rude and impertinent behaviour on your part, and not acceptable whatsoever.
So what is your problem with answering direct questions ? - lack of any real foundation I am now fully sure.
How long since you left engineering school - last week and still wet behind the ears ?.
We have all met young graduates who are sure that they know all there is to know regarding electronics.
If such engineers were really worth their mettle, then I would not have "25 Years Experience fixing Engineers' mistakes. "
Your replies furnish this more than adequately.
Eric / - sick of dealing with idiots.

This is true only if adequate heatsinking is provided, elsewise mosfets fail just like any other transistor.
Did you miss a lesson ?.
I actually do not care in the slightest, but in the interests of honesty I thought that you would provide such information so we all have an idea of who we are communicating with.
Your replies furnish this more than adequately.

Re: Re: Re: a big enough liabilities
The idea that designers do not listen to program through their prototypes is clearly as absurd as suggesting chefs don't taste their culinary creations...
...probably one of those accusations that people hurl around without much thought i suppose...
