| Negative feedback Amp=more faithful reproduction? Mapman, Woofers have only one invention - lack of suspension (spiderweb) compensated by large diameter voice coil mounted to flat disc in place of dustcap. It makes membranes lighter, faster and stiffer. Midrange (6.5") uses, in addition ferroflui... | |
| Negative feedback Amp=more faithful reproduction? Mapman, That's the first thing I hated - The looks of two small coffins in glossy black (I hate glossy black). Overtime they grew-up on me and now I love them. (It is a little bit like Eiffel Tower or glass Pyramid if front of the Louvre Museum, o... | |
| Negative feedback Amp=more faithful reproduction? Sorry for double post | |
| Negative feedback Amp=more faithful reproduction? Edwyun, this particular design (Icepower) uses Nielsen Karsten multiple feedback. One feedback comes from modulator while the other is from the speaker output. Class D is relatively linear to start with, while output impedance is inherently low he... | |

| Negative feedback Amp=more faithful reproduction? Dracule1, What I'm getting from this is that some amount of imperfection can sound to many people more natural. Difference between natural, pleasing and faithful is fluid. Article was very interesting and thank you for posting it. I would only dis... | |
| Negative feedback Amp=more faithful reproduction? Edwyun, Yes, we have to realize that when they talk about zero feedback they mean global feedback. Amplifier can have many local feedbacks and they might still call it ZNFB. Why? Because ZNFB became catch phrase and sells amplifiers.You stated the... | |
| 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 either... | |
| Triode mode vs pento mode Atmasphere, there might be some issue since triodes have lower internal anode resistance leading to higher damping factor and perhaps perception of less bass.Pentodes are less sensitive to supply voltage variations meaning that large change in sup... | |
| Negative feedback Amp=more faithful reproduction? Many people like sound with some distortion that makes it more alive (distorted guitar vs clean guitar). My Benchmark DAC1 sounded too clean at first but it doesn't anymore (learned to listen). Many accused DAC1 of sounding sterile. When they comp... | |
| Negative feedback Amp=more faithful reproduction? Dracule1, I glanced over article and it seems to cover pretty much everything. I will read it in detail.Stereophile also conducted experiment with adjustable feedback amplifier and they liked sound at minimum feedback. It doesn't mean that feedbac... | |
| Negative feedback Amp=more faithful reproduction? Negative feedback reduces harmonic and intermodulation distortions, reduces output impedance and widens bandwidth. This can be easily measured. Negative feedback, especially a global one, can introduce Transient Intermodulation Distortion (discove... | |
| Best $4 I ever spent on audio Yes, they use 4562 but very likely lowered rail voltage - nobody sane would risk overvoltage failure in mass production (rail voltage in DAC1 is +/-18V) especially when voltage regulators initial tolerance can make it additional 2x0.5V easily.They... | |
| MP3 vs Hi Res Steve, I don't really like headphones, using them only on vacation etc. Tube amp is not that portable and is not battery powered. My tiny E07k works 22 hours on single charge.AKG k271 mkII is not perfect but has better midrange and lower bass exte... | |
| Best $4 I ever spent on audio You have to be careful since NE5532 is rated for 44V total supply voltage while LM4562 is rated only 34V. It would not work in my Benchmark DAC1 so I used LME49860 (11 of them). It sounds a little better than NE5532 but it depends. Some people pra... |
