But don't forget: The engineer of yore
a) didn't have Har-Bal
b) had to take into account that the recording had to be vinyl compatible, that is to say there were sever limitations as to what was possible in the lowfrquency spectrum (dee beeyas, mon!).
Luckily with CD technology, that limitation is a thing of the past.
It is interesting to know that the thing that sparked Paavo to start the Har-Bal project was that he wasn't satified with how his records sounded on his custom-made Hifi speakers.
I am sometimes amazed at how good some records are mastered without the use of Har-Bal (Supertramp, forexample)!
How the hell could these guys do it? Sorcery or

Black Magick, I bet!
