| Negative feedback Amp=more faithful reproduction? "Mapman, the question here is if NFB makes reproduction MORE faithful. Some answered that there is no faithful reproduction, which doesn't answer this question, while others stated they prefer sound of ZNFB which doesn't answer this question eithe... | |
| Bob Carver 180 Mono-blocks perform superbly Sovtek KT88s? I think those are even cheaper than the stock tubes, and they sound better than the stock? That's great. I have the Telefunken smooth plate 12AX7s. | |
| Negative feedback Amp=more faithful reproduction? The degree of feedback needed is dependent on speaker that is driving. You make a valid point. The designer purposefully built feedback into the amp. I don't necessarily understand the article fully as my technical knowledge is limited, but I can ... | |
| Negative feedback Amp=more faithful reproduction? Edwyun, I have an amp with adjustable feedback, so you can change feedback while keeping every other parameter constant. In this case, feedback can have a significant, if not drastic, effect on the sound. So stating feedback alone has little effec... | |
| Non-feedback amplification topology and frequency Thanks atmasphere. That is a plausible explanation why SET amplifiers which almost always employ zero NFB sound more involving (dynamic) than reality. I've found SET amps with zero NFB to be less accurate than PP amps using NFB. | |
| Negative feedback Amp=more faithful reproduction? Mapman, I understand those who say just enjoy your gear, there is no best. I'm not looking for the best. And I am not looking for validation, nor am i unhappywith my gear. Some on this thread mistakenly make these assumptions about the intent of m... | |
| Negative feedback Amp=more faithful reproduction? Mt, please start making sense. Start your own thread to vent whatever frustrations you have. You're just trolling here. You'll get no more response from me. | |
| Negative feedback Amp=more faithful reproduction? Phaelon, you may be thinking of Rethem speakers which have powered subwoofer drivers with a wide bander taking care of the rest of the freq. they are coming out with low power ZNFB amp for their speakers. I think with powered subwoofers the low fr... | |
| Negative feedback Amp=more faithful reproduction? Mt, I'm sure your system sound awesome to you, but I've had my fill of single driver fostex speakers with low power tube amps which have significant drawbacks IMO. But you're getting off topic, and I do not see a reason to resort to personal attac... | |
| Negative feedback Amp=more faithful reproduction? Meant to say its NOT the way things sound in real life. | |
| Negative feedback Amp=more faithful reproduction? Kinjanki well said. That had been my experience with NFB as well.I'm not looking for validation. I've been in this hobby for close to 30 years and I know what I like. I'm searching for technical explanation of why we hear what we hear. I have list... | |
| Non-feedback amplification topology and frequency Marqmike, a zero negative feedback amp does produce odd order harmonics. Please read the link I provided. It will answer most of your questions. | |
| Negative feedback Amp=more faithful reproduction? Elizabeth, I have and owned amps that have adjustable NFB, and you can clearly hear a difference between different levels of feedback. IME, the higher feedback setting produced more realistic sound. So your contention feedback has little to do wit... | |
| Negative feedback Amp=more faithful reproduction? Hi Elizabeth, what is a current fad or "catchphrase" is not important to me, but the finding the underlying reason for "catchphrase" or current fad is. If I did't think NFB or ZNFB made a difference in sound, I wouldn't have made this inquiry. | |
| Negative feedback Amp=more faithful reproduction? Hi Kijanki, thanks for your input. What do you think about the article I linked? |
