clean, box up ones u don't use. and store in your house.
i very much felt like crap, after selling many, many components when we moved.
i still miss the onkyo grand integra tuner, onkyo tx 840 and 860 receivers, the rotel rb1090, from which the buyer from egay, was a complete a$$bag,
few other pieces as well. old jvc cd player, older technics EQ, some Infinity bookshelf speaks, ....
if you sell, you will regret it.
