Brass screws make a real difference on Dunlavy s ?

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. ;-)

It's a screw thread not nuts. 🃏
