In my space, the thinking is the same - the levels of "obviousness" are very different - but the fundamentals are identical. That's also part of, my "method" - which people work desperately hard at trying not to understand - even invoking The Big Guy, 😁. It’s not hard to “not understand”, Frank.

GARBAGE !!! In a good system it is easy to hear differences between PSUs with much lower output impedances at either end of the spectrum even when the Output Z is already quite low.. This even applies where a Capacitance Multiplier circuit is used, where you can still clearly hear the difference where low ESR or Audio type capacitors (e.g. Elna for Audio) of the same value are used, and that's with a simulated capacitance of a couple of FARADS !!!.. P.S. You have already verified the last part for yourself with files that you listened to, where the exact same amount of capacitance was used, but with different types in a capacitance multiplier How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

gmgraves Posted August 4, 2020 Share Posted August 4, 2020 15 hours ago, fas42 said: @kumakuma has already spelt them out - here, The rig I had 30 years ago had a power supply problem in the amplifier - poor choice of smoothing caps - fixed by assembling a far more effective array of smaller caps, having much lower parastic resistance, better construction. The current active speakers have a sensitivity to mains noise - which I'm currently working out a solution for. This is known as: Find a Problem; Fix the Problem - very obscure approach, usually taught only to car mechanics and similar ... Frank, a car person who wants to become a mechanic can get step-by-step instructions from mechanic’s vocational schools, books, high school shop classes, etc. When a mechanic tries to start a car, and nothing happens, he knows that either the ignition switch, the starter button, the battery, the solenoid, or the starter motor itself is faulty. Books and teachers or more experienced mechanics can tell him and show him where to start to find the fault. But you tell people nothing! You just assert that your method achieves miracles. But unlike a mechanic or a mechanic’s teacher, you are silent on the “mechanics” of this fabulous “method” of yours.. I guess what’s frustrating for most people here, is that you should be able to list each fault you find and then list the fix. Like this: Audible line noise - Added isolation transformer to mains supply. Found hum being induced to phono system - moved turntable line cord away from phono lead. Poor bass - Redesigned power supply with stiffer capacitors, replaced resistor in pi filter with 400 milliHenry choke (show schematic). Etc. But you’ve never given us a step by step breakdown of symptom/resolution. If what you are doing is, as you assert, analogous to a automobile mechanic’s troubleshooting steps, then like the mechanic, you should be able to list the steps in your “method” to fix each problem area. ...And not with such vague explanations as “replaced RCA interconnects by soldering various audio components together” Either. For instance, what perceived fault did you think such an action would address? What were the actual results as opposed to what you thought they would be? Seems to me that rather than prattle-on for thousands of posts about what you are trying to accomplish, that you would WANT to give us a step-by-step primer about how your “method” works and how you go about applying it. What steps do you take to ascertain the level of “surgery” required to fix what perceived faults, and how efficacious are these specific fixes. Finally give us the methods you use to continue to tweak a system when all of the obvious steps (that most audiophiles already know) have been applied and their benefits noted. It is also apparent to me why most folks here question your veracity when you are not forthcoming with the above step-by-step outline of your “method“. You’ve posted enough verbiage about what you’re “trying to do“ to have written “War And Peace” and you could have avoided most of it just by “coming clean” years ago with the info I outlined above.

As I predicted you tend to align yourself with @ray-dude to try and establish some sort of credibility, presumably the nature of the endgame, best quality sound. Ironically, it only serves to highlight how absurd your claims are, to achieve like quality with such low end gear. You wax lyrically about what good sound is. You always conveniently ignore the fact that your non-existent method applied to low end gear cannot produce such sound quality, and that it cannot be better than 99% of the high-end gear owned by the members in this forum. This is insulting to the members of this forum and I believe that you are well aware of this. You play them for fools. When asked for evidence you can't produce it because it doesn't exist. This is why you will not produce photographs of your magic handiwork. You just produce another episode in "Frank's Fables" which really is just another way of insulting people. It is extraordinarily highly likely that the vast majority of members in this forum have greatly superior sound quality than you have ever achieved in your entire lifetime of tweaking low end gear. It is extraordinarily highly likely that the vast majority of members in this forum have already got much closer to your very own descriptions of what is good sound quality.
