Brass screws make a real difference on Dunlavy s ?

Many of you report a difference after tightening the screws on the drivers ("it helps", "it was beneficial", "worthwhile") and I remember reading of this before. No one in the thread describes what changes occurred to the sound of the speakers after tightening the screws. Bass more extended?, resolution improved, clarity improved?, more coherent?

Martin Colloms' article on, "PRAT" gives some good descriptions of how and why tightening speaker system screws can affect your reproduction. Especially page 5: ( http://www.stereophile.com/content/pace-rhythm-dynamics-page-5 )

Good question(s) Foster. What I noticed was a modest amount of additional transparency. It is the sort of improvement you get when using a good CD cleaner or beveling the edge with a lathe. Last night was fun using some very familiar high def CDs as reference, and then applying most all my standard tweaks in addition to the tightened screws. I have never heard the reference two channel system sound better. This evening I plan to do the same sort of thing to the reference HT room to see if similar improvements are found. I will post the results.

Foster--in my case the bass was better defined, the sound a little more transparent as a result. Not earthshaking, but noticeable.

When people wonder "Why don't more people love (high end) audio?" threads like these are exhibit A. Audiophiles don't get a nutty reputation out of nowhere. ;-)
