| Class D Technology The output filter vs switching noises frequency is the bottleneck for Class-D HF distortion and low impedance drivability.It is ill minded and made up. There are many amps that have similar bandwidth and great reviews. My tiny amp is listed as 3... | |
| Class D Technology Georgelofi - you are talking about harmonic distortion below 0.1%, that are inaudible (unless you're a bat, of course). I've noticed that you also tried to apply psuedo-science to sigma-delta converters. I am afraid one day you'll find that SACD... | |
| Class D Technology Rowland model 102. There are many class A or AB amps that have similar bandwidth but nobody talks about phase shifts. | |
| Class D Technology Mapman +1. Georgelofi - if you don’t like the sound of particular amp or even class of them just say it, but making up pseudo-scientific reasons is just plain silly. | |
| Class D Technology If bought down low to erase most of the switching noise, this intrudes into the upper frequencies of the audio band. Which makes it very smooth but robs most of the harmonic structure of the mids and highs, this "could" be compared to tube or clas... | |
| Class D Technology Just because you heard a class D amp sound better than a tube amp in a particular situation does not mean that all class D amps sound better than all tube amps, or even that the particular class D amp sounds better than all tube amps. It just mean... | |
| Class D Technology I will state just the opposite. Violin sounds like violin without scratchy glazed harmonics of class AB amp. Same goes for the cymbals that sound brassy and meaty instead of bright and splashy. Cello sounds deep and resonant. Transients are in... | |
| power conditioner Farzad, many people complained that dynamics were reduced. In typical linear supply current is drawned in spikes of very high amplitude. Any filter element will cause a voltage drop, hence reduced dynamics. My conditioner Furman Elite PFI 20 ha... | |
| Class D Technology Nonsense. Not only that I don't know what they mean by "Pumping back the energy" in half bridge configuration (that I use all the time) but at least they don't mention limited resolution. Such statements: However, the differential output structu... | |
| Cheater plug safety erik_squires, +1, It is important distinction - chassis ground is different from the signal ground (in IBM computers system and chassis grounds is the same causing all sorts of problems). It was mentioned here that IC might not provide adequate g... | |
| Class D Technology Sorry, Randy-11 but this article is garbage. The critical fact to bear in mind is that all Class D amplifiers have outputs that are comprised of discrete power increments, a notion that can more easily be thought of as resolution steps.Class D amp... | |
| Class D Technology Mapman +1. People are tossing terms like "nonlinear" or "lots of distortion" without even understanding the principle of operation. I can understand when people don't like sound of particular class D amp with their speakers, but tossing pseudo-t... | |
| Cheater plug safety Lifting ground in amp designed to operate with ground plug (Class 1) is always a safety risk. There might be amps, like Parasound design to operate with or without ground, but when it isn't don't cheat. Amp without ground plug is designed differ... | |
| Class D Technology Ralph, Karsten Nielsen doctorate work at Technical University of Denmark is available on line. Here is volume 1:http://www.icepower.dk/files/ph.d.thesis/Volume_I_Title_and_preface.pdfSorry to hear about your injury. My daughter has sciatic nerve... |
