het part 2

I'd say yes, I agree with oldhvymec. I don't cover my stuff except for turntable, but I have HEPA air purifiers that I run continuously, except when listening. I haven't tried silk, but sounds good because it's virtually lint free and not abrasive.

If you want trouble cover it nobody covers amps and preamps.HELLO!!

@ebm,

FYI, I cover my McIntosh MA6600 integrated.  It sits out in the open on top of my audio rack.  There is a guy on FB who makes custom covers for audio equipment.  I paid less than $40.00 for a custom cover that perfectly fits my amp.  It’s black on the outside and the inner side has a soft cloth. The model # of my amp is on the front of the cover.  At this time of year, no more pollen on and inside the integrated.  

Sounds great to me.

@ebm, your answer is not complete. only reason why i ask about this is because of the dust that falls on my units. what do you suggest i do???
