What brands tend to have the worst resale value?


I couldn’t resist this topic which obviously contrasts with the post on the other side of the equation.
In all my years buying and selling gear I think that Soulution gets hammered more than anything I’ve ever witnessed. I’m sure it’s great gear so there’s something that I’m missing. Mola Mola looks tough as well. Late generation Krell pretty weak too. 
What are some other candidates?

It seems that anything I buy fits the bill. First Snell, then Threshold, then Dunlavy, then Classe. The list goes on.
I was disappointed with what I sold my Manly Labs 300 Neoclasic preamp for,and how long it took to sell. I did get it at demo price but it still stung when I sold it. What I replaced it with ( not going to mention a name) I purchased used. Funny thing if I were to put my current preamp up for sale right now I wouldn't lose a dime, and it's not a mainstream brand.

Manly Labs? 
Resale on those bound to be right up there with Porsh and Ferarri.
Complex high tech components drop in value significantly as they become obsolete when new technologies are available. In terms of brands, I have never seen anything lose value quicker than Lexicon. Take the MC-12B preamp. The MSRP was $14K, and you can easily buy one for under $300. IMHO, that $300 is generous for such a horrendous machine. 
just have to hope you can get a 20-30% discount on an in demand product. with some leg work can almost always be done whether arc or mac. still going to lose a solid % of entry price. cables have to be bought 30% off but resale is very tough
