Just a technical question to the EEs on the forum. If you have two amps, one is rated to supply 100 watts and the other rated to supply 400 watts, and both are playing at a specific volume (let's say 90 dB), and you are using the same speaker, the power to the load at that SPL will remain the...

This might be a silly question but can amplifiers affect pace, rythm and timing of music? I've heard the term PRAT being thown around on audiophile forums.   Is there any part of an amplifier that could possibly affect things like this, or is it totally bullcrap? My first thought is how can...

Sorry, I should have been more clear. I am talking about speakers, not headphones. But I think I understand what you are saying and the 1 kHz test signal makes sense. Thanks for the post!   However this :   So if one measures the left and right channels and there is imbalance then...

  It would be great if someone could actually show how this is done, not by words, but with a video. Posted on Youtube, for instance, showing how it's all done.   I would love to be able to level-match my gear, but I wouldn't know where to start. If someone could show how it is done in real...

Can someone please advise me on something. I've always believed that driving an amplifier at higher levels meant that distortion would increase, even below clipping.   I've also been told by many audiophiles and salesman that it is far better to drive an amp that has power in reserve, so that...

I may have asked this question before, so I apologise in advance, but I would like to get someone to build me some DIY speaker cables (single-wire), I am a terrible with DIY, but I really like the work I've seen in this thread. If anyone is willing to help, please send me a PM for further details.

Can someone please explain something to me about power. If one amp is rated to deliver 100 watts and another is rated to deliver 200 watts, will the 200 watt amp be able to supply more current into a speaker than the 100 watt amp? If I have a 100 watt amp supplying 50 watts and a 200 watt amp...

Some people I've heard on other audio forums claim that AVRs can sound just as good for music as a stereo amp. To me it's unfair as an avr is a processor even in pure direct its simply too busy with too much going on. (5-11 power amps) lift the lid on any decent stereo amp and if will find very...

But How does fragmentation affect the sound quality? Things like the tonal qualities of the sound? Because I thought that if there were errors that the music would be garbled, or parts missing, or something of that nature.

So then it could just be hearing bias that caused him to hear a difference. Or he looked for a difference that wasn't there, or expected one.

So one of my buddies told me yesterday that his USB powered hard drive and his externally powered hard drive changes how his music sounds.   Serious. He told me that when he played his music through his Asus O Play mini if he used a USB powered hard drive the music sounded flat and just...

Wow, you seem intelligent and well spoken. Your input on something else would be appreciated. When comparing electronic gear, and hearing differences, there is a cause and effect. In sighted listening test, the effect could be a result of a different cause.   So if listening to music with two...

  Based on how I understand the argument, what some people are saying is that like a helmholz resonator, if you whistle/blow over the bottle until you find the correct resonant pitch then the note emancipating from the bottle is lower than the whistle. So based on the fact that there is a...

I have a question about harmonics. The fundamental is the lowest number in signal analysis and the harmonics are integral multiples of that number.   But I've heard from some people that you get subharmonics too. Frequencies that are integral fractions of the fundamental. There is a discussion...

Steve, if one amp has a different gain structure to another, does that mean one amp can apply more power over a more narrow portion of the volume pot compared to another?   Like some amps may need you to wind them up, if they have a lower gain. It's interesting, because there are times where...
