"Final voicing – the last ~5% – is done by ear. Why? Because any audible changes brought about by smaller component changes can be heard but, once fitted inside a loudspeaker or pre-amplifier, cannot be measured. "
And right there we move from science to pseudo-science BS.
Also: There's no audible difference between any functioning CD transport and any other functioning CD transport. There *cannot* be. The reads are 100% identical [* note: laser X might be better at getting through scratches on a damaged disk than laser Y]. The fact that they make and market transports at high prices is another.
I've listened to the speakers shown here. I generally liked them but was not blown away. That said: the room was not ideal.
