I add no sounds, the pure artists' music is here. I don't digitally extract stereo, for I think that's messing around with sound.
With « processed 'stereo' » I mean: fake stereo.
Nowadays I no longer use « processed 'stereo' » but I prefer « wide mono » .
I don't earn money with this (it only COSTS me money), so please don't be offended if I play around with sound, it is my hobby, I do not intend to be wise or smart, it's just what I like to do...
These edits are best experienced via headphones... if you want advice:
Sennheiser HD 520 II (I have one, sounds nearly perfect)
Sennheiser HD 580 [Precision] (my wife has one, sounds perfect)
Sennheiser HD 595
Sennheiser HD 600
Sennheiser HD 650 or even... a Sennheiser HD 800 (VERY expensive)
Shure SRH 940 (sounds nearly perfect)
I MUST WARN YOU: there are also inferiour Sennheiser headphones! Don't just trust the brand!
The latest with a good review by my local newspaper's music specialist is the Sennheiser HD 560 S.
