LINN LINTO NOISE

Raul, Good to know I could shut down my 3160 before amplifiers, but I will continue to do the normal routine; amplifiers first.  It's not a hardship.

I took a look at the Stereophile review of the Linto.  Apparently it has a switching power supply and a highly compact-ized audio section using SMDs and op amps.  It's a simple box construction, and the S'phile reviewer made no mention of a muting function.  Not much to go on.

Luigi only wants to know whether other owners of the Linto have had a similar experience to his. Since my dear mom often used to call me Luigi, I am empathetic.

Personally, I’m a belt and suspenders kind of guy. I mute the preamp and then I always shut down amplifiers before preamplifier.

It's not at all uncommon to hear a thump or other brief noise if you shut down a preamplifier ahead of shutting down the amplifier.  Some more expensive preamplifiers protect against that phenomenon by employing a relay that clamps the output when power goes down, but not all do that.  Consequently, I always shut down amplifiers first.  In an extreme instance, you may damage a speaker otherwise.  Shut down amplifier first is your solution.
