Passionate...... we'll call it passionate..... I get it!!
I did the caps on a pair of JBL CF150's and it was like new speakers... I have done early B and W and seen no difference, I've done some Marantz Imperial 6's and huge change...
I swear it is all hit and miss as far as a change.... But it does help to do the best you can... then you can go onto other shit as the reasons for shitty sound.... LOL
thanks,
Darren
