Tom Thiel you have sparked a light ball in my brain. Eddy currents are another descriptive term that falls into the file cabinet of interfering energy. Same goes for shear wave interference and boundary interference. Right angles are a simple eyeball example..to be continued.. TomD

We first discovered eddy currents in the steel baskets of the O series. When we auditioned the phase coherent version we heard weirdness, but the phase-correct / time incorrect third order slopes 'erased' the weirdness. We thought it was mechanical / vibrational, but all the epoxy we could pile on the basket didn't help. It turned out to be magneto electrical eddie. Aluminum baskets cured it. Later we tried aluminum voice coil bobbins for their thermal conduction. Eddies were purely electrical, but problematic nonetheless. This wavelaunch stuff I've been working with lately is a manifestation of the same effects in the realm of surface propagation and boundary layer turbulence. And, of course, the binding posts. Jeff Roland first brought that problem to my attention. They had put huge output posts on their amps seeking better performance and a marketing ploy. They failed sonically. Yep, same file cabinet. |
@theaudiotweak, It was you, I checked my old receipts, don’t ask me why I still have receipts from the early 90s. I appreciated your assistance. You also were able to provide me with brass point stands for my Thiels, you knew someone that made them. Thanks. Anthony |
Hello Anthony, Glad to know we are both still around. The points I supplied you were most likely Audiopoints a product line that I have long supported and do till this day. If the points are attached to a metal platform you have a Sistrum platform now called Rythm platform. Both have brass points with a select geometry facing up and down attached thru the channels of the platform The company name is now Live-Vibe Audio. Let's keep in touch. TomD |
@tomthiel thank you for the in-depth analysis of cable options for the 3.7. Morrow sounds interesting but it looks like they are hard to get here in Europe. I think I stick with the idea to look after some Straight Wires. If I buy used ones even the top-tier Straight Wire Crescendo or Serenade are in reach. |
