Yes you can. They can be a valuable resource. I priced my set a few years ago at about $1.50 an issue. Sold them the next day.
Disposition of old TAS/Stereophile
I've held on to my TAS and Stereophile hard copies (maybe some other audio mags, too) from the past, but have pretty much decided to let them go and free up some space. Have others found homes for these besides putting them in the recycling bin? Can you actually sell them given what it would cost to ship?
