Well, That's a good lookin' rig there! I dig that acrylic under it! Tell me, do you think acrylic is a better insulator than 3/4" Birch plywood exactly like your setup 2 layers with cones? Should I get me some?
I have the Xpression3 running a Grado Silver 1... Sounding not bad, but it took a month of settling, and many re alignments! The best is starting with the protractor, and working from there using my ears!
I have a Denon DL-110 @ the Soundsmith now getting a ruby-line contact can't wait!!!!
But I really like your rig, and is that the Pro ject Puck in there?
