Here we go again...

Off Topic....

So, should I assume that everyone has acutally used the LM4562 / LME497x0 opamps that started these brouhahas in the first place?

I've found them to be quite exceptional where and when used appropriately. Very possibly not the ultimate for the scratch built, bespoke component, but for a yokel like me, faced with the shame of monolithic opamps polluting our paths, these chips are far less evil than those they've replaced.

Very few have actually opined based upon actual experience.
I've been quite impressed with how the initial discussion went from how good the National chips may or may not be, to one of Aristotelian Ideals.

If we want to publish rebuttals, Walt Jung has found the 16 page rebuttal to Bob Cordell that we tried to publish in 1980 in 'Audio'. Should we try to put it here, in order to maintain balance?

Hi John,

That was about 25 years ago, so I could be wrong, but I don't ever recall seeing that. The reply letter to the editor you guys wrote was just recently furnished to me, as I had looked and could not even find that. My attic is a mess! I think I may have replied to your reply, but I have not found that either.

Anyway, I'm very interested in seeing that 16-page rebuttal of yours. Was it longer than the original article?

Anyway do go ahead and post it. If you can't post it, or choose not to, please email me a copy of it to Bob@cordellaudio.com.

Cheers,
Bob

I also have your 6 page reply to the rebuttal. Perhaps that will refresh your memory of the paper.

Does Walt still have a copy of the letter from that SUNY professor that claimed we had to have faked those null balance capacitor tests?

My true point is: 'People who throw rocks, should not live in glass houses.'
Chas Hansen wrote a letter to the editor of 'Stereophile', expecting it to be a LTE, or an editorial. It wound up in the back of the magazine instead.
For some reason, Bob Cordell decided to criticize the letter in public, rather than in private, like he recommended to us, decades ago, when we did the same thing to him, in 1980.
By the way, when Indira Gandhi, many decades ago, was shown a microprocessor chip, she asked what it was made of. The answer to her was: 'SAND' To her surprise. Actually, 'dirty sand' would be more accurate, don't you think?

Hi John,

Thanks. Please email both to me.

Cheers,

Well that clearly settles the argument.

Nothin' cleaner than pure, unadulterated vacuum.

Yeah, especially when it is between the ears.........................

That's me!

First of all, John, it was Charles who was recklessly throwing the rocks here. Letters to the editor like that are always fair game for disagreement. I think it is a shame that you try to distract from, and derail this thread by injecting a different 25-year-old controversey here.

As far as what happened 25 years ago, I will happily believe any assertions you make about the interaction when you show the material. I suggest you post it in the permanent feedback thread, where it belongs.

Quite frankly, you have been harping about that extended "rebuttal" for years now, and I have just assumed that you were blowing smoke. Maybe my memory failed me. We are, of course, both growing older . Show me the letters, and I'll be happy to at least eat crow about their existence.

By the way, I'm a bit mystified that you even thought that you had a chance to get a 16-page letter to the editor in Audio published. What did Gene Pitts tell you as the reason why he did not publish it?

I think that, largely, my article on TIM in Audio has withstood the test of time. It is available on my website at www.cordellaudio.com for those who would like to read it and decide for themselves. I welcome debate on it.

Cheers,
Bob

 

[john curl]

But Bob, one would need the rebuttal to: 'Another View of TIM' to get a balanced input.

If it's a 16-page reply, then it will probably be too large to post on the forum. Maybe Walt could add it to his site and post a link here?

 

[john curl]

We still need permission(s) to send it to anyone.

You guys need permission to post up/send an unpublished document that was written by yourselves?????

Dum dum di dum dummm dummm dummmmmm dummmmmmmm....................................

 

[SY]

John, email it to me and I'll host it and post a link here in a separate thread. And any further related material by you, Scott, Bob, or (with his permission) Walt Jung. That way, everyone is arguing off the same page at least.

 

[dimitri]

Two more persons were involved

 

[SY]

Fair Use, at the very least. I'll host it, so it's my risk.

 

[AJinFLA]

Can anyone direct me to a list of recordings owned/used by Charles Hansen, John Curl, et al?
I would love to hear for myself even a sampling of their vast collection of pristine, op amps/NFB free recording chain sound, not embedded with those horrible maladies, that plague the sound of many playback systems.
Anyone?

cheers,

AJ

Sheffield? Wilson? Crystal Clear?
