Should we care if a piece of equipment comes from a pet-free, kid-free, smoke-free home?

I almost sold nothing of all the pieces i bought, save two pieces.

I had kids and pets...

And anyway i modified all my gear pieces, even headphones,  save the speakers Tannoy i sold and the tube amps...😊

i cannot sell anything of the system i used... My 2 akg headphones are modified , the speakers also...

I can sell the two dacs  and the two chinese amplifiers, there is no internal modifications...

I never sold my books or cd...

I gave them or put then in trash...

 I dont like the trouble it takes to sell ...

😊

I am not rich but i dont need money...

Aside from the smoke smell, equipment from a smoking home accumulates a layer of nicotine that discolors the unit and clings to the electronics. It is not impossible to clean, but it is not easy. I used to hand out in an audio repair shop with a friend who is an engineer and repair tech. The pieces that came in with nicotine residue were easily recognized. It's not something you would want on your purchase. 

Interesting to see the politics of some of the responders. 

While pets, smoke and kids are somewhat of a challenge, nothing is worse than that awful Febreze/fabric softener/dryer sheet stench. It permeates existence itself when used by its victims.
