Brands that have the least depreciation

McIntosh for sure.

I'd add Totem to the list....many after the 1st year 50% drop they remain pretty much there.  Some classic models like the Mani 2 have barely lost resale...or increased !

I say Bryston, you rarely see anything on the used market.

My view is to buy products that bring the love of music to your home. Products that you value the most are valuable to you. They stay with you for a long time. Enjoyment in music is the price you pay.

IMO, contrary to what others posted , you can objectively know what products have better resale value than another. it's a given fact that some products whether audio, video, cars, boats, etc hold their resale value well , while others do not. If you do not recognize that ,well then you may be losing alot of $ if your the seller and making great deals if your the buyer!
