| Preamp and impedance question Savvy how? I am sure I can match them in patents and AES papers. Really doesn't matter, since they would all agree with ME, not with you. You don't even realize that you have not made any arguments to support your claim and have done nothing to sh... | |
| Low volume listening dynamics wolf-garcia, you can get that response out of an older tube amp and high efficiency speakers often. | |
| Preamp and impedance question @georgehifi , all you did is regurgitate what you already said, without in any way relating EPDR to a tube amplifier, except in the way you used it, it is wrong. EPDR is not impedance and-does-not impact frequency response w.r.t. output damping fa... | |
| Why no interest in reel to reel if you're looking for the ultimate sound? No offence, rrcpa, but you don't seem to understand thermodynamics or sampling theory.When you record on tape, something is lost. Tape is neither infinite bandwidth nor infinite signal to noise, and even speed and level is not consistent, hence so... | |
| Big source improvement using CD player It's one of the reasons I listen to radio during the day. If I stream, I am too easily distracted to change the song. | |
| Why no interest in reel to reel if you're looking for the ultimate sound? WAV is no higher resolution than FLAC, Apple Lossless, or any other truly lossless format.BTW, I use WAV which is the highest resolution and no longer available for HD down-loads.You can speak with authority on your setup for recording and ADC, an... | |
| IM Distortion, Speakers and the Death of Science Doppler distortion presents as IM distortion and is inherent in moving element speakers. That element of what is measured as IM distortion cannot be designed out except by narrowing the frequency range of the driver, and by larger drivers requirin... | |
| Why no interest in reel to reel if you're looking for the ultimate sound? It was a fine attempt @cd318, but alas, you attempted a discussion about religion, and that never goes well. Are high-res digital recordings more accurate than tape? ... of course, but good luck within a given crowd of having that discussion.There... | |
| Damping Factor - Interesting article See my later post where I deleted one of my previous posts ... too much on the brain and wasn't paying enough attention. I was never implying that speaker response is not impacted by amplifier impedance. I was more questioning the "constant power"... | |
| Damping Factor - Interesting article I would expect it is not very high output impedance / current output driven, though it may have a relatively low damping factor and may have some current feedback. The issue is most speakers today are designed for an amplifier with high damping fa... | |
| Preamp and impedance question @georgehifi , Maybe you could explain to gte357s, exactly how this EPDR is "taxing" a tube amplifier knowing that being frequency based, and real music, the time at any of these EPDR minimums is very short.@gte357s , changing the tap from 8 to 4 o... | |
| Damping Factor - Interesting article It is not an electrical flaw in the speakers. It is primarily a mechanical design choice. The site you linked is good, but it is easy to draw the wrong conclusions if you don’t read in depth.A pure current feedback output is not ideal as it will p... | |
| Preamp and impedance question Why did you make a post, delete it, then create a reply to it like this? I don't understand.Post removed Jun 08, 2020georgehifi7,214 posts06-08-2020 4:58pmPost removed Jun 09, 2020 That's right.Clean up aisle 4. | |
| Damping Factor - Interesting article atmasphere,I deleted my old post questioning your article as I misinterpreted what your point was and where you were coming from. Put my head into a different mindset and completely agree in principle w.r.t. what you were communicating w.r.t. cons... | |
| Damping Factor - Interesting article Doing 4 things at once including posting here :-) ... sorry for my error. I meant impedance is halfed, but had V-squared/R on the brain :-)An amplifier that doubles in power as the impedance is squared will keep the most consistent anechoic output... |
