| Class D amplifiers. What's the future look like? Class D is switching, but there’s no analog to digital/digital to analog process involved. It’s all done with feedback. :) @erik_squires You can build a class D that is zero feedback as well. | |
| New Generation Class D - AGD Audion Mkiii upgrade Now, and with all due respect, the simple fact your last reply cites the "input capacitance", is an obvious demonstration of the gap in the fundamental know-how of semiconductors in general, and for sure in III-V material devices that exists on t... | |
| What is meant exactly by the description 'more musical'? All this sounds simple yet we have many amplifier makers. I suppose most have gotten the "bad" distortion out of their designs, though. @hilde45 If that were true there would not be a tubes vs transistors debate older than the Internet itself! ... | |
| What is meant exactly by the description 'more musical'? @hilde45 I think I can boil this down a bit. In the text below, I'm repeating myself in several different ways. For a designer's point of view, if they understand the rules of human hearing perception, they can design (if they understand the tech... | |
| New Generation Class D - AGD Audion Mkiii upgrade @agdproduction The reason I responded the way I did is because your 'explanation' lacked anything that pointed to an audio application. So perhaps you could be a bit more specific. For example, having a lower gate capacitance as advantageous, but ... | |
| What is meant exactly by the description 'more musical'? a good sound experience has little to do with taste or money and not even with only specific better design quality of a specific component as much useful are a better design and it is ... Yes, like many endeavors, high end audio is driven by in... | |
| What is meant exactly by the description 'more musical'? Clearly, you and others have discovered there is a widespread predilection for 2nd and 3rd order harmonics, and there is a predilection for sugar, fat, and salt, too. But all of those preferences could be changed by changes in taste @hilde45 H... | |
| What is meant exactly by the description 'more musical'? I have always felt this term to be equivalent to "emotionally engaging" and standing in contrast to analytical or accurate. @erik_squires IMO/IME equipment can be emotionally engaging and accurate at the same time. But not analytical, which IME... | |
| New Generation Class D - AGD Audion Mkiii upgrade @agdproduction Does the ability to build a GaNFET class D of our own design from the ground up, have it meet EU Directives and get nice comments about it and such, that I somehow I am misunderstanding the explanation and the physics of the sem... | |
| External Tube Amplifier Power Supply Connectors Molex makes a line of circular connectors which can do the job with ease. Since you don't need much in the way of current and the voltage is nominal, you have a wide range of connectors you could use. Its a good idea to bypass the connections ins... | |
| What is meant exactly by the description 'more musical'? What if someone’s ear does not care about the kind of distortion @atmasphere identifies with musicality? Would we say their use of the term "musical" is incorrect? This would be tantamount to saying that "good food is spicy food" and then for any... | |
| New Generation Class D - AGD Audion Mkiii upgrade @agdproduction Your description simply sounds like a good switching device (i.e. GaNFET), combined with good engineering arranged to make an amplifier. I'm very aware of the difference between efficiency and good sound :) | |
| What is meant exactly by the description 'more musical'? I’m going to add to what @mapman has pointed out. Musicality has everything to do with how the amp makes distortion. The main differences we hear between amps, their ’sonic signature’ is in fact their distortion. To be musical, that distortion ha... | |
| Are SET amps "quieter" than push/pull tube amps? Can anyone explain to me why a low powered SET would be more "quiet" and work better with such speakers than an ARC Ref 75 or VAC 200iq (as examples)? @bobbydd Yes. The dealer is incorrect; PP amps are not noisier. But, and this is a big one, t... | |
| New Generation Class D - AGD Audion Mkiii upgrade I'm pretty sure that the GaN FETs that AGD is using are the only ones actually designed from the ground up for audio. @badgerdms GaNFETs are designed as switching devices. To that end, they really can't be designed for audio other than to be s... |
