| 20 year old solid state technology..... or has electronics at this level not evolved that much outside of "subtle refinements"? @phasecorrect In the 1980s there wasn't a single amplifier design made that had sufficient gain bandwidth product to support its feedback across the entir... | |
| My VERY POSITIVE Experience with VTV and Warren Coleman (Attention: Sound Lab Owners!) The Sound Lab loudspeakes are, in my experience, and simply put, THE BEST ESL CURRENTLY IN EXISTENCE. Agreed! | |
| New Generation Class D - AGD Audion Mkiii upgrade Always buy that which can be upgraded instead of the "one and done" inferior design that doesnt keep up with the newest technology and innovation possible. Yes, its always a good idea to make an amp easy to service and update! | |
| Class D amplifiers. What's the future look like? @erik_squires Sure- that would work :) | |
| 300b lovers I changed the load resistor from 57K to 39K Ohm. The difference in square wave overshoot is very small, but frequency response peak is just +0.5dB instead of +1.3dB. You can also see that bandwidth has opened up a bit. Something to keep in mind... | |
| 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... |
