A good result is not when mixing clipped signals to clean ones, but when a crest factor is being decreased by a soft clipping limiter. The record becomes "louder", less chance to damage it by dirty clipping amps.
No magic here. I've experimented with it a lot, and found that nobody likes added distortions, no matter what claims, rather presence of one distortions (less audible) versus presence of other distortions (nasty sounding) is being preferred by people. However, some "audiophiles" adhere to a "Cargo Cult" and believe that "a signature" is what is needed by "Real Audiophiles".
How about it's just a naming issue. By "signature" they mean "we preffer this way of doing things". As compared to the more unpleasant one. Just what you described, but in different words.

The problem is, Cargo Cult Audiophiles prefer to HEAR some ADDITIONAL distortions.

I guess we're now going in that territory where they're not audiophiles but businessmen helping to sell the expensive signatures.... 😉
1n34 does something like a soft tube clipping. Never heard of paralleling those with a silicon diode, interesting.
Did you hear about saturating transformers used by some sound mastering engineers?
Speaking of an expectation bias... ;-)
If you connect all bases together, no bias, to the input of your opamp, there should be huge nasty crossover distortions, right?
Not necessary... Add a resistor (something like 47 Ohm) between bases and emitters and listen... And compare... 😀
Sometimes it is better to discard odd entities, searching for Graal. 🙄
Very effective (plus cost and space saving)
Thank you Wavebourn 🙂

Yes I have. Did it some myself in my tracking days. Guitar amps and preamps use the effect too.Did you hear about saturating transformers used by some sound mastering engineers?

That be true! But it is a large and vocal cult.

Sure. Also Norah Jones insisting to record her first albums with Walter Sears. Tube mic preamp et all. She was quite successful, wasn't she?
And I recently fixed a couple of WM-D6C for someone still recording with them.

At this point I should mention the MAGAMP or magnetic amplifier, this is a transformer based OPAMP. The drift is poor and gain not really too adjustable and the frequency response (depending on excitation frequency) really a few Hz, but it filled a requirement in it's time.
A steel mill in Rotherham was still using them to alter the field (I think) on motor-generator sets for DC motor speed control until very recently. Last 5 years or so.
Control of the Primary Mill manipulator sets was described as like "two majestic galleons on a heavy sea". Not close control 😀
With 6" of backlash in the gearboxes and tossing 20T hot slabs around, it didn't really matter. Delay on the joysticks meant you had to be on the ball when bringing them together. Overshoot and delay with 2,000HP and a lot of inertia meant a big clang despite sticks full apart!
I don't think they are "saturating transformers' as described above for audio, but the principle sounds similar and they might be with a higher excitation frequency. More info please!

Guess we could call it the LCMkI 🙂

I don't see what the issue is with this, tbh. No magical violations of physics or needing superhuman hearing ability. Preferences can be what they may!
No not yet. I just ordered chips and sockets from mouser last night.btw morinix, did you have the time to try a FET input opamp instead of the LT?

Sure! Nothing bad if people prefer planes made of hay! 🙂

If there is a problem, it most likely arises with another aspect of human nature, which is a tendency to automatically attribute cause and effect. If one system apparently sounds "better" than another, it may be incorrectly attributed to it being more accurate or more realistic. It is probably audiophiles, in an attempt to explain their equipment choices, who naturally feel a compulsion to construct what may be seen by others as scientifically implausible explanations of cause and effect as to the how and why of their preferred equipment's superiority. It's, in part, a way of justifying to themselves and to others (in a way plausible to them) the seemingly good reasons for their choices.

More like having a preference based on the engine noise.....

Exactly. 🙂
"High End made in China hybrid car with Bugatti sound and Ferrari colour. The best of 2 words!" 😀
Back in the 80s, when Lotus were doing active noise reduction they had a demonstrator vauxhall astra that had a choice of engine sounds, including SBC and air cooled flat 6. VAG have started re-using a form of this in some of their turbo nutter cars.
Some hi end cars change the sound of the exhaust depending on drive style - but through the internal sound system! At the outside it is still docile and softly purring...

Electric cars of the future with customisable retro petrol/diesel engine sounds, why not steam sounds lol.
More seriously, what is the sound of modern electric vehicles...older ones I have heard produce a constant whining sound, possibly they were UK model variants.
