het part 2

@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???

Custom vinyl cover on my integrated cool running amp.  Gotta keep the Maine Coon cats and Golden Retriever hairs out!  Not to mention the normal dust and pollen.  I’d contact McIntosh to get their opinion.

By all means cover your McIntosh but not with a mcintosh.

Can you feel any heat on the top of the metal cases for either units when they are in "standby"? If you can't, I would say the recommendation of silk would be much more desirable than plastic vinyl. There will be a very slight amount of heat that could be detected with an infrared thermometer.

Get a light  cotton cover and dust with a Swifter only.
