brass notes lack bite but sound the cleanest by far

butchered, cymbals are a mess, not enough high frequencies

probably strikes the best compromise out of the 5 samples

1R Comment: Slightly "dull", appears to lose some fidelty both in the treble and in the lower, more "soft" sections of the sound.
Appears to lack some "kick" in the midtones too.

3L Comment: Drums appear to get "washed out" in some way -- they sound less defined and are ringed. There is also overall some distortion.

4L Comment: A lot of loss in the higher frequencies. Apart from that I can't hear that many artifacts. Sounds perhaps a tiny bit disharmonic at places (?).
