Outlaw Audio RR2160 MKII--Knobs, buttons are made of ??

The Outlaw web site has photos but I am not sure if the knobs & buttons on front panel are metal or plastic?  Thanks!
Most likely plastic like the 2150 was.  I had one of the first 2150, its balance and bass controls were plugged in wrong at factory.  Bass was adjusted with Balance, Balance was Bass knob.  Sent it back, second one had a serious channel imbalance.....sent it back    Hope the 2160 is better QC wise
There were QC issues with the first released RR 2150's.  Outlaw changed factories and things got much better.
