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? 
Any brand that changes models frequently.
Any component that is technology based like a DAC, music streamers, DSP etc.  As new technology is released, the older tech gets devalued.

I would say, anything insanely priced (retail) takes a biggest hit on the used market. Outside that, you can expect to get 55-60% value off the full retail on components that are still in manufacturer lineup. Cables are the worst...they de-value like anything I have seen.
Yep, the Bose acoustic wave machine once $1300 or so, right around $50 - $100 on ebay
Yorx and Lloyds are a close tie!
Lol.  Most of the mentioned brands I had when I was a teen. The worst was York.
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.
Happy Listening
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
I have four Sunfire Subs in my basement that NOBODY wants to buy!  Man, they are great subs, but old news today apparently.  I upgraded to twin SVS SB-16 Ultra subs and they are a lot more along the lines of what people are looking for.  And of course, who uses just one sub any more?  Suckers!
anybody remembers the supper brand "York" sold by Price Club ? i believe nothing ever was worst then that ! Sound , design , quality was atrocious !

Linn. I never saw worst profit margin
Nola Loudspeakers, Edge amps. MSB TECHNOLOGY. In the UK most equipment that is not distributed by Absolute sounds. 
Pioneer, Kenwood, Sony, Onkyo, Harmon Kardon. Even big honking Sony and Onkyo receivers are a dime a dozen. 
Manly Labs?

All three brands misspelled!
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”. 

... 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.

This is a big reason I went with the ps audio FPGA based dac. I get free upgrades every 6 months whereas most other dacs become more out of date, plus the ps audio dac is very very good. Even manufacturers that build components with individual boards for future upgradability miss the mark, expensive to start and each board is expensive. 
‘I hope classe makes a comeback
Does anybody here remember Soundesign?  The worst stuff ever!! 
At least you won’t lose much money on Sound Design. 😁

I think there is a difference between "junk" audio and gear that doesn’t get it’s due. I walk the vintage audio road and there is gear that I have tried that gives great audio but doesn’t get the respect it deserves...

Interesting you mention Realistic. I have heard that the Lab (400, 500) series turntables are actually quite good. I read somewhere that Mitsubishi made the direct drive motors for these and they are very good quality. Haven’t picked one up to try. The Realistic brand, unfortunately, shadows it as "low rent".

Weren’t some of the earlier Realistic speakers using Altec drivers and horns?

The components that don’t seem to hold their value relative to their performance (for me) were from the small boutique brands like Apt Holman. The AH One is a great little preamp. I had one early in my journey and it sounded great. You can still get them for $250-350 in the used market with prices slowly climbing as the word starts to spread.

Tandberg amps and preamps don’t get their deserve as well as the Sony "TA" series amps and pre-amps. The Sony TA N80ES amp and TA E80ES preamp give spectacular audio and are still a great value if you are willing to walk the vintage road.

I have a Realistic LAB-440 and it's a pretty sweet table. I think I paid about $400 for it. 
I guess I only paid $135 for the LAB-440.  It sold for $219 new back in the early 80's.
Hands down worst depreciation are Wilson Audio speakers, e.g. Alexia new $55k+ but used 1 to 2 years later $16-20k

Martin Logan, Vienna Acoustics, Anthony Gallo, Linn, Definitive Technology...these brands tend to sit on Craigslist forever.  

I’ve bought only used gear for the last 15 years or so. I try to stick with brands I know will give me most, if not all of my money back when I resell It (eg McIntosh, Manley phono). Buying before listening to a component is a crapshoot, no matter how good the review is. The worst one for me was a wyred 4 sound integrated, STI-500 I think. I overpaid for it used, hated the sound, and promptly fried the left channel (don’t ask). After getting it repaired, I sold it after months of trying, and lost quite a few dollars on it.
Vapor Audio Prob the Worst, 75K Speaker not worth more than 10K in today's money.
Vapor Audio.   Aptly named.  
I I have classic Infinity speakers, never really liked the sound, spent money upgrading the internals, invested elbow grease refinishing the exterior and now they proudly sit in my basement waiting for someone to bite at my ridiculously low asking. Fishing in a Manhattan puddle yields more bites
The reasons are many for a product not holding value, with the most common being that the MSRP was too high and once the advertising hype is gone, the item is not so great anymore. 
Someone mentioned the Apt-Holman preamp and it was a great amp, which I enjoyed for many years, but the printed circuit boards were cheaply made causing the leads to lift.  I had mine repaired once, but PCB deterioration made further repair impossible, so I gave it to a fellow who had another.  Also, you can bad mouth Japanese gear if you want, but the reliability of their stuff was outstanding.

One of the many contributing factors that  has influenced the more traditional home audio solution is the home theaters in a box, sound bars, and the big sound Bluetooth speakers.  

I think some of the well designed  “vintage” gear can outperform the more modern equipment.  

Occasionally when family and friends ask me for audio equipment advice.  I usually recommend that they consider “vintage”equipment with the suggestion that they have it serviced.  
Emerald Physics. I have a great sounding pair, that short of giving them away,I can't seem to move.I have even greatly reduced the price to no avail.
Soulution  gets hammered so low because the mark up is crazy so high your talking Italian sports cars prices . You can not drive your power amp to work .
Keep in mind that it's not uncommon for the original buyer to get 15 - 20% off MSRP. So in reality, some brands are doing better than might appear.
