What brands tend to have the worst resale value?

Pioneer, Kenwood, Sony, Onkyo, Harmon Kardon. Even big honking Sony and Onkyo receivers are a dime a dozen. 

Manly Labs?
Resale on those bound to be right up there with Porsh and Ferarri.

All three brands misspelled!
Bravo!

Most commodity level equipment from box pushers like Sony, H/K, Pioneer, JVC, and the quasi-no-name brands tends to rapidly depreciate. It does serve a purpose, for people who don’t really care that much about quality and just want “something that gets the job done”. 

ebm... Your cynicism throughout many threads of late is getting a bit long in the tooth dude...maybe a long walk will help.

So many answers to this.  The ones that get me are the really great components that are just priced way too high.

Manley Steelhead - this is as good as it gets for a phono stage.  I used one for a few years.  No way I'd pay $8400 for a new one when you can get a used one for about $3500.

Trenner & Friedl Art - one of the best shoebox monitors out there (I own an older pair), but the new model is $6000, which is ridiculous.  You'd be lucky to recover even 50% of that in resale.  Most people are going to walk right on by to the Harbeth P3ESR which costs about a third less.
