So you did not do any kind of controlled test?
Why is it when I viewed this on youtube the next suggested video is about the Battle of the Coral sea? And I've neither been looking at military topics lately or anything related to navies. I expected to see where the USS HiRes was part of the action.
Many find it hard to believe that they have a problem with their equipment, especially those who have spent a lot of money on them. The limiting factor can be many things. When I removed one, another one appeared that the first one hid until I finally had the current sound. It has taken me a lot of time and effort to get it!
That is a pointless test. MP3 was designed to encode music or speech with little perceptible distortion. A steady-state multi-tone signal is actually fairly easy to encode, as these graphs show. The somewhat higher noise floor is perceptually masked by the much stronger tones. In the second sample, the noise level drops in the gaps, exactly as it should. The assertion in the last paragraph is in no way supported by the figures, nor by anything else.Year: 2012

With decent recordings it is very easy to differentiate between MP3 320kbps (LAME) and FLAC 16/44. If it is not the case, it is that you have a bottleneck in your system that prevents it.
This is an interesting observation. MP3 compression destroys the phase relationships between fundamental tones and harmonics. When this processing is applied to music, percussive sounds tend to become bursts of noise instead of identifiable actions. I find that this is the most disturbing artifact produced by MP3 compression. You seem to be describing a somewhat similar effect. Accurate phase response is very important when reproducing transients.
Do you mean that with the Marantz, Kef and a few 'tweeks', you can hear subtilties in WAV that make you distinguish them from mp3, whereas you can't in other homes with expensive systems?A second hand AV Marantz SR4500 tweaked and modded. Same with KEF Q100 5.25" coaxial speakers. And the other components too. Few DIY devices to clean the electrical grid, RF/EMI. And...

HelloIn 2011 I have not the KEF and the Marantz and...
My main system sounded great but ended up being kidnapped by television, family and loud music After a few years I went back to listen to music but it turns out that it sounded much worse than I remembered! I speak of excellent recordings. So I decided to buy a second-hand amplifier to be able to experience improvements that I had read out there.
By the way, modern AV sounds much worse than before, I mean for music.
Well, you definitely have golden ears. I'm unable to distinguish between a well encoded 128kbps mp3 VS WAV/FLAC.
A lot of streaming radio uses 128 kbps, and it sounds terrible to my ears. I guess they could be poorly encoded.
Interesting. So do you consider that all mp3 have a bass boost and lack treble? Will hear again to check.I barely hear MP3. The few lossy files are OGG -q9 that I have recoded from FLAC for the phone. I have saved this EQ (JRiver MC) for a long time:
And SoX 96 in Output Format, I think.
