Thanks. It just seems to me from videos that some boards are easier than others to silence. Some are metallic boards with ample space inside, and can be quite pingy, hollow, and echoey. Then, there’s videos of Tofus that have 10 tons of silencing material inside them, and are on 3 mats.
Seems to me something like a Tofu65 would be a good candidate for a small board. I’ve seen even the stock KBD75 made into a quiet board in a Silent Alpaca review. The question this raises in my mind is whether the polycarb PLA75 would be even quieter.
But yes, I would probably just try to have a board squared away and dampened as much as possible, no matter the manufacturer. There are step-by-step guides on dampening a GMMK and Zhuque, which shows how a common or inexpensive board like those can be quieted.
