>Something can't be described as "straight wire with gain" unless it gives you at the very least -- a ruler flat frequency response, and you're not going to get that from something that has a damping factor hovering around 10, and no feedback. As someone once said, "Less is more until less is just less."

No ones ears have a ruler flat freq resp. Our response all differs due to age and other factors. The only standard (purely IMOH) for reproduction is experience of the original performance compared to reproduction of the same. All else is abraction layer or layers.

Coda: Awesome photo of the Cunningham/Radiotrons. Have about 6 in their orignal boxes.

dear edwinr,

after all the fuss over the "BIG THREAD", why not buy what you want. as facinating as i find the debate, it's really all in your head. get what you want, don't stir the the pot just to see if it will still boil over. i can't believe you would start all over again after starting it "again". that last thread nearly made me want to sell my stereo and move to a place with no electricity. i think this is a cool place with some very helpful folks. personally i think the math speaks volumes. that is my opinion. i don't care who likes it. i do not come here to impress anyone or start some controvercial line of crap that few want to read. buy it, listen to it, ask questions if you have them, but let this one go away.

sorry if i have stepped over the line all you venerable non-punctally challenged correct spelling pc friendly folks but i can't take another hate fest. i will watch and if it is me that is the ignorant one then i will go away. i have no problems there. i really do not think this needs to keep going on and on.

I think everyone with any experience will agree that microphones have a vast range of sonic differences one to another, as big of a difference as different speakers.

If a performance, captured through microphones and associated equipment, then treated by a mastering engineer, then played back through one of any number of speakers, ends up sounding exactly like the original performance, that's astounding.

And that's assuming a perfect amplification chain, just for fun.

Very likely you'll have one part of the chain fighting another part, one thing a little too much one way, another too much the opposite way. A slightly dull microphone and the mastering engineer will increase the highs with EQ, and then if your speakers are on the bright side, it will sound too bright and would have been better left without the EQ boost (for your system).

Considering that microphones do not "hear" things as our ears do, and that there are such a wide range of microphones, I don't see how comparison of a recording to the original performance (which is in your memory only) can work in evaluating an amplifier, when the whole recording is compromised from the get-go.

I knew before I ever heard it, by factual analysis, that SET wouldn't suffice, and this has subsequently been confirmed repeatedly by me in listening tests. But you are absolutely correct, it is much better to listen to equipment for yourself and decide for yourself. It's the only way to do it that makes sense when you are faced with such divergent opinions.

Unless one HAS a straight wire with gain, how does one make a comparison to it?

Any invention should be as simple as it can be, and as complex as it must be, in order to serve the purpose.

For any invention, such as an amplifier, there is a point of balance when less or more will both be harmful to the function. The enthusiasm for simplicity for it's own sake, is entirely unrelated to the physical reality of the thing itself. There are many "simple amplifiers" I've examined ( or built myself) which were useless by simply being too simple: falling far short of it's full intended purpose. The visual appearance of simplicity - few parts, for example - should not be confused with the aesthetic of simplicity. A plank with four crude wheels may be simple compared to a Honda Civic, but that simplicty translates into nothing useful for transportation.

The hardest thing in engineering is hitting the balance point.

OK, seriously...

Very nice and insightful posts here. I was quite surprised when I clicked. I expected a thread resembling a school bus running headlong into a big bix of kittens. Thank you all for surprising me.

I'm still with Tony and the rest of the subjectivists on this. I know, big shock.

"The only standard (purely IMOH) for reproduction is experience of the original performance compared to reproduction of the same."

I agree with Paul. I've been told several times that microphones themselves "sound" different. On a completely different "note", different studios as well as concert halls all have their own particular "sound", and even varies greatly depending on where you're sitting in relationship to the performance. The "original performance" is like saying you like "the original taste of a hamburger" -- which is just as vague and doesn't really tell anyone much of anything. When we say "straight wire with gain", we are talking about the theoretical -- whether or not a preamp or amplifier has the ability to deliver the source signal in a completely unaltered and pure form. Sorry, but this is the complete antithesis of what a SET amp does.

Dean, good points. First of all, I should really hear a good and bad example of SET sometime so I can take my viewpoint out of the abstract a bit. But I don't know if I'd change my atttitude about the issue.

I've experienced exactly what you describe as a matter of course. World class mics, world class rooms (not too many of those, naturally), world class musicians(well, to be honest, not enough of those, either)... It's mind-opening to take a fantastic sounding source, mic it with a Neumann U47, and listen to the character change with a movement of a few inches in the same great room. Is either better? Take that great Fender Twin and put in the bathroom rather than the studio & mic it up. Better? Worse? Right? Wrong?

Situations like these make objective dictations on others' preference tough for me to bear. I'm happy to see posts like Craig's square waves way back when, though I probably raised some hell at some point over it. Now I may give in too easily on the facts, as I don't really care about the objective issues. Distortion? A little bit never hurt anyone, as long as it's the right kind, right?

Anyway, I don't think I'll ultimately let quantitative issues get too much in the way of qualitative judgement. That is, if I can get preamp lust out of my blood and audition some different power scenarios.

Well, a bit of a ramble, and some incomplete thoughts there that I might get slammed for but...
