Thanks. After a couple days of use:
- The knobs are metal, with smooth action and a solid feel.
- It came with four rubber stick on feet. These are necessary because the corner screws can scratch, but the dog bone shape forces the feet to be placed a little back from the corners. The screw posts float over thin air and might still scratch with sloppy handling. It’s stable but I wish it had true corners or flush screws on bottom.
- The sound quality is very good. I may leave it in place for some everyday use.
