So, I came across yet another person the other day who was enamored with the idea that they could simply swap some opamps out in their gear and have "pro" gear from non-"pro" gear.
It's a theme I'm afraid will never die, no matter how much any real engineers fight it. There is just too much draw for someone to think they can get something amazing for little to nothing invested, besides some time and some solder. Even then, most of the people I come across who want to do these things have no real intention of doing this work themselves, which is part of the problem. They want to invest no time in studying nor understanding. They want and they want it now!
So anyway, I was probably red in the face when talking to this person, after they kept interrupting my explanation (of why what they were doing was absolutely the worst thing I've heard lately) to continuously tell me that someone on an internet forum had done it and said it was good.. Soooo, they were going to pay that same person to do the mods for them..
Conflict of interest, anyone?
Anyway, even though I'm an engineer, and I really try to do a good job at it, I was pretty much told that my thoughts were not going to change their mind and I was wasting my time. Now they were the ones red in the face. What gives? They were the ones who approached me! It very much seemed exactly like a lot of internet threads, they asked a question with the purpose of hearing a comforting agreement. They wanted reassurance that their idea was the best and that they are going to get their something for nothing. Not so. I'm pretty truthful and I don't play games like that, which is probably why I'm middle aged and single, but that's another story!
So, in a last ditch effort, I was going to write a simple explanation of all the things this person would have to go through to do the job at hand correctly. Once I finished the first paragraph I realized that I probably wasn't the person to write this. Online and in my personal life I write like a layman. I understand that things need to be simple and straightforward because nobody would read more than a few sentences if they don't understand them. I write professional reports at work, and they are expected to be wordy and full of lingo and engineering-speak and ultimately full of nothing but data and facts. BORE-ING. That's not going to work.
I was nosing around on the internet looking for a concise description of what I wanted to say and I happened across a webpage that pretty much summed everything up in a fairly simply way, with an example that seems relevant. I want to thank this person, whomever they are for writing this, because it's exactly the types of issues you'll run into by just "swapping opamps" in a design without any consideration of the actual design. I hope those who intend to do some swapping read this page and realize that they are most likely hurting their project rather than helping.
