I received another Sol care package today. Small but weighty, it was a new motor can base and a small pack of screws with star washers. Carefully packaged, but no notes or anything else. TLDR is that Schiit sent a new motor can base with a large solid rubber base instead of three small feet, and it appears to improve on motor can vibration and stability. Wall of pictures incoming. Here's what was in the package, next to my motor can. I was a little surprised that they sent an entire new base, metal and rubber (or feels like rubber at least). Top and bottom views of the base, side by side. New is on the left. The metal part appears to be the same between revs. As this is inside the can or outside of view I don't have any opinion about differences in finishing. Installation was simple: remove the three screws holding the existing base in place, replace with the new, and put the screws back in. I wasn't sure if I was really supposed to use the new screws with star washers or not, honestly, so I reused the existing screws. Incidentally, the motor can has the traditional red Schiit circuit board inside. After installation, mass is up 50 grams, or 8% over baseline (with the original heavier pulley installed). Before, 622 grams: After, 672 grams: The new base itself is 312 grams, indicating the old base was about 262 (I didn't measure it). So, differences. The first is that the can no longer has a tendency to tip in certain orientations if you set belt tension too high. This was a minor issue that I don't think was a real problem in practice, but improved quality of life is probably worth the change. The second is that the can appears, in initial runs at least, to vibrate less on my cheap IKEA LACK table. Previously with the motor running I could hear a quiet but audible hum from the pod. It was always mechanical, and I never heard anything through headphones or speakers. That hum appears to be significantly reduced, as has vibration of the can to the touch. Unfortunately I didn't do this as a direct before and after and didn't think about it until I had everything set back up, so I'm going from memory. So overall this appears to be a nice change, and hopefully won't have any unforeseen downsides. And I would appreciate feedback on if I was supposed to do something with the small pack of screws and star washers.
