Bill - I just checked and you're probably right."dual monaural pure path preamp" and such. and oh, btw, it's now called "hi end" as to differentiate from the plebeian "hi fi". tee hee.
You don't measure so you don't know or care, empirical cobbling of components can produce anything you want just tweak and listen.
That's classic. It's gonna fill her face with wireless RF waves.
Up until now I thought the worst mistake one could make was talking or singing into the top of a side-address mic.
I used Audissey once to correct my line arrays, concrete woofers, and concrete subwoofer under floor; no need any more to correct anything.
What were you asking? I thought I was describing a design process, where all you might need is a cheap multi-meter to make sure things are hooked up properly. I've worked with folks doing stomp-boxes, etc. rolling obscure stuff was the norm. One good find was 60's era pulls from IBM computer boards, the germanium PNP's were way bad and made the best distortion and noise. 2W carbon comp's the whole 9 yards.

I was asking whether you have a model describing how the numbers you measure translate into acoustic perception and public preference. See post 3025 for the full question.

Nope, see added links above. Typical rock LP goes through a wall of effects boxes even after fuzz pedals etc. I couldn't hope to keep up with that. Second one, extremely detailed mathematical analysis and simulation of a famous effects box. Conclusions, no clue as to why one version is preferred over another.
So op-amp rollers supposedly hear differences, fine. My experiences are not credible anyway because I used "those?" speakers, or "their?" pre-amp, or the music was mixed by "that?" guy.
Let me clarify this. It's not about your personal experience being valid or not. That you would know better than anyone else. It's about accepting the fact that others may have different experiences.
I have no problem with that. I do have though an issue with those that would lie about their perceptions. Some do it for financial gain. Others just to troll forums.
Sure. It says that I don't sell anything audio related and I don't describe my perceptions here. Now tell us about you.
I can't tell the difference between Lf353 and opa2164 operating into a max 2.2k load no capacitance.
setup: opamp gain of 5 then output into 2.2k then out to amp / cables etc.
the newer opamps will perform a better RIAA curve as they have 100 -120db of open loop low frequency gain.

You guys are always referring to people like me talking about audio for financial gain. That is just BS, I LOVE audio, and I am one of the few people who FOUND my hobby could be and remain my occupation as well. I doubt that anyone here would buy my best efforts, although you might find something used that was designed by me, as a well engineered bargain in audio. In fact, that is what I would recommend to anyone like me, who does not make a whole lot of money in their profession. For those who do make a lot of money, then my best efforts are worth consideration, because real money and time have been put into their design and construction to give the best performance, whether any of you can actually hear the difference. Someone out there will appreciate them.
Sorry John. The comment was targeting those helping to sell cable elevators, Shakti stones, LP demagnetizers and the likes.
Now you're really confusing me. John's posse believes in some of those things, in at least one case strongly. What have Jan, SY, I, and others done but criticize the same stuff? Do you have us all confused with some one else?
BTW if you think I have something to sell you are sorely mistaken, I post here solely as a DIY'er and could care less whose op-amps you roll it is of no financial benefit to me.

Shakti stones are news to me. Just read a 6goons 'review' of them, WTF! how can someone gullible enough to actually buy them acquire money in the first place?
Maybe by trying to dismiss snake oil beliefs and products we are actually doing the opposite, by accident. By mentioning them and arguing endlessly about them we are publicizing them. The saying "there's no such thing as bad publicity" might also apply to consumer audio related sales.
