Sorry to rock this boat even more. I have all of the listed clamps above, (VPI Delrin and Stainless, BDR 1 and 2 piece). The clamp that I found sounds the best is the Teres Audio Cocobola clamp. It's $200, alittle cheaper than the BDR and IMHO sounds better. It's also the prettiest clamp of the camp :-)
VPI Record Clamps
To make a long story short my 1 piece record clamp threaded out on me, so I bought the new one with the stainless knob. Then I noticed in a Music Direct catalog Black Diamond Racing has come out with a carbon fiber clamp for $300. The guy at Music Direct talked mt into it. I tell you this thing kicks butt. If you're looking for a new clamp to replace the cheap plastic clamp that comes with the Scout or just looking for an upgrade I'd check it out. It sounds fantastic on my '19 MK IV.
