As well as the Motif and S6000 listed below I also have a Sony A8 DAT recorder and a marked pair of JBL EON 15s for sale.

There are a few marks on the Sony and the JBLs are quite scuffed but still work and sound great.

I used to have the original Eons. There were instructions in the owner's manual to take sandpaper and rub down the marks. They are very easily marked and this makes them SMOOTH again.
