I got the brass plate mounted on my 103 and I hear a different cartridge. The brittleness in the top end has disappeared. The bottom end also seems tighter and better defined. Vocals and stringed instruments are more present and realistic. Stevie Nicks voice on Dreams (Fleetwood Mac Rumours) is stunning. In the past, it's felt congested and edgy on my system. That's gone now.
I sandwiched a thin piece of shrink wrap tubing between the brass plate and the tonearm. Some folks have recommended this as a means to damp. I was extra careful aligning the cartridge. The exposed cantilever makes it easy, but I wanted to make sure I got it right. I added weights to the RB300 bearing joint (Twl's tweak). And I used the weight adjustment on the Tecnoweight to set the tracking force (2.5g) rather than the spring-loaded knob on the RB300. It's probably a combination of all these things that are creating the improvement, but the end result is wonderful. The cartridge is more enjoyable and less fatiguing than I ever remember it. An ebony body will come at some point, but I'd like to settle in with this new arrangement for a while.
