| CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS Put another way, we want the amp to be able to run at full power indefinitely. | |
| Low Level Listening and Distortion I believe in the past you said you like to be able to listen to music at louder volumes and it not sound too loud. @bhvf That's not exactly right. What I've often said is that its the mark of a good system that it can play at high volume withou... | |
| Let me end the Premp/Amplifier sound debate ... The fundamental error of Julian Hirsch, and most 'Alikists' is believing there is a correlation between a static measurement and a complex dynamic process. At best there is a Venn diagram-like overlap. Another poster mentioned that no component c... | |
| Why do I need power management if I have a great power cord? Power cords obey Ohm’s Law. Voltage drops across them can cause a very measurable loss of power in an amplifier. In that manner it can affect distortion and output impedance too. The voltage drop is easy to measure with a regular digital voltmete... | |
| Class A or Class D solid-state amplifiers (modern designs) What have you been able to glean about the long term reliability of class D amps, what goes wrong, and what is the result? Electrolytic caps last longer if they have a charge on them and they are not subjected to heat. WRT the other parts used... | |
| CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS Can you make a higher power amp with this module or is it limited to output as designed? We can, but we're holding it to a rather high standard: At present, the amp can sit at full power with a sine wave input all day long- something you simply... | |
| CLASS D MONO AMPS buy ATMASPHERE MUSIC SYSTEMS Well, those inefficient speakers will flourish with more powerful and higher quality and affordable class D amps. Maybe. But its a simple fact that with less efficiency comes more thermal compression. Its also a simple fact that if you make a p... | |
| Low Level Listening and Distortion In other words, a "clean" sounding amp (think stereotypical class D) 'Stereotypical class D'?? IME class D amps vary more in sound from one to another than all tube amps. It sounds like you are talking about that 'first watt', which has to be ... | |
| Tube amp question While I agree with you that a tester that cannot properly test a KT150- shows the limits of the tester, ( BTW, yours- nor any Hickok- I am aware of can test these tubes--and your KT88 spec is no good for them) it also points to the fact that they... | |
| Class A or Class D solid-state amplifiers (modern designs) @petaluman As you might expect I have read Nelson's article before. He addresses the issue of poles in the amplifier caused by adding more stages of gain and how that adversely affects the use of feedback. I addressed that issue in my first post ... | |
| Tube amp question @falconquest Plate voltage is the voltage on the tube from cathode (usually at or near ground) to the plate of the tube. The plate is exactly what it sounds like; it receives electrons that flow from the cathode. The audio signal is imposed by the... | |
| Class A or Class D solid-state amplifiers (modern designs) That analogy doesn't hold water, if you see what I did there. | |
| Tube amp question KT150's require 600 volts at the plate. @daveyf @falconquest This statement is false. If you look at the tube's specs you'll see that for class A operation (single tube) 400V is recommended. This would be the most current you would want to... | |
| How much difference does a phono preamp really make? The front end of the system is where you really have to get things right. It makes no difference how good your amps and speakers are, if the phono section isn't right (along with the turntable/cartridge itself) there's no way you can make up for t... | |
| Sound Better w/Amp Directly Into Wall Then Thru Zero Surge So I’m wondering what is happening in or to the amp to cause this change in sound? Again, the rep from Zero Surge today said that there shouldn’t be any difference. "It’s just wiring." Emphasis added. That is exactly what the issue is! When yo... |
