I've said already, I downloaded them, found they were MP3 and stopped right there. If you want to do something like comparing amps you should have used a lossless format. Even if I could hear differences, I didn't care to use my time knowing it was MP3.Ten days have passed and no one has commented on whether or not he has been able to differentiate those three amplifiers. And only one, daftcombo, has promised to do so.
To be a forum where there is so much comment about measurements, objectivity ... it is disappointing.
Hi Maty,
I downloaded the files. It's 4 clips, each recorded 14 times with 14 differents amps.
What are we supposed to do now?
Okay, I have more than one problem. So I don't waste time comparing amps with MP3. It is okay if you want to do so. I just don't.Idea: If you are unable to differentiate between those three DIY amplifiers, you have a problem.
I already noticed the low sound quality which surely makes the test more difficult but the difference is evident.
What is the point of proposing tests to verify the quality of the equipment in certain fields if the previous one, so easy, is not exceeded?
Have you tested yourself in any blind manner like in Foobar ABX?With the problem, I mean those who seek a neutral system and try, as far as possible, to be faithful to the sound of the recording, which is what should be common in these forums.
If the system is very euphonic then it will not matter not to be able to differentiate because its owner has other things in mind.
Many say they are unable to differentiate between MP3 and FLAC. Despite the low sound quality, the MP3 is encoded at maximum quality. Presumably the same test with better sound quality and format (FLAC 24/96) would be even easier!
The good thing about this test is that the audios were not created by me. They are available in the diyaudio.com thread but are scattered.
Have you? Post your ABX log to show us how easy it is.But, with all those problems and limitations, have you been able to differentiate between those three DIY amps? That is the question.
