Why a dearth of some brands on the used market?

Maybe people actually like them and keep them.  

Dyns are for sale because many customers keep stepping up the ladder.

I heard the Devores directly after listening to Dynaudio and Harbeth and was totally underwhelmed after all the hype I had read. May have just been me.

I also agree with @yesiam_a_pirate regarding quantity produced. Also, there are different types of products made for different types of audiophiles. Not all audiophiles are gear swappers, but those that are tend to be attracted to brands that target them. Those brands also sell a large volume and then release new, upgraded products often, which drive a percentage share of consumers to sell their older ones off. 

It had always been on my bucket list to own a pair of Luxman M-600a amplifiers to use as mono blocks. They are by far not the most expensive or coveted Luxman amp, but they rarely show up used in excellent condition - seems people are listing ones that have a good amount of cosmetic issues. They have been discontinued for years, and only a small population own a pair. A single in stereo mode is 30w of Class A into 8, 60w into 4, but in mono BTL mode each amp becomes 120w of Class A into 8 and 240w into 4. I also like their form factor and aesthetics than any other Luxman piece (all of which I regard quite highly).

I finally found one and purchased it while I’m really happy with the performance of it, I can see where a second one would deliver the added control and resolution I am missing against my reference system. So I’m patiently waiting for another one in excellent shape to come off the market. It may take a year or so, but I’ll wait.

After spending $5,000 on a cable, the owner is not going to chop it in for $1500.

Another consideration is the volume of units produced. Some manufacturers crank out units by the gross, others hand build only a few examples. 

I'm looking for used chord cable- music xlr in shorter length. They don't show up often!

One reason Transparent comes up for sale often is because of their liberal trade 

up policy.

Just buy it new

A ton of Elac and Dynaudio speakers on the used market…if they’re so good (supposedly) why are owners constantly dumping them?

My tannnoys are not for sale...😁

LARSEN 9 speakers

the reviews are intriguing but have only a very limited NA  distribution and availability for this Swedish design and build floorstander .

based on the tech news and reviews , they may be a potential fix for crummy room issues because they are designed to be placed up against the walls.

great post @bluethinker 

I run a lot of searches and have a pretty good idea. 

I know what's hard to find that I looked for, and I also looked at each company's revenue to be able to weight things. 

 I didn't do a spreadsheet so these are my impressions:

Cambridge Audio, NAD, Rotel, Parasound, Bryston - lots of good deals

Jolida - lots of on the used market

Hegel - very rigid price-wise

Similar story for the speakers, Klipsch, JBL, older B&W models everywhere.

I seem to see a lot of Transparent Audio stuff on the market. Don't know if people were trying it out and not happy with the cost/reward or if there's just so much of it out there that you're just going to naturally see more of it.

@bluethinker66-

 It did take some tweaking from my original purchases to get things "right" though.     

                                                Of course!

    One good aspect of buying cabling from known/reputable/highly regarded companies (aside from increased odds they will perform), is that they are so easily sold, on the global market.

        An easy half of the dozens of cables I've owned/auditioned (we're talking: over a few decades) were sold/shipped internationally.

I have budgetary numbers I am comfortable with, typically based on what I may have paid for a product in the past that I want another of. When I see prices beyond what I deem reasonable, I pass, unless I am feely spunky that day and "lowball" someone.

As for many well-known cable brands being in abundance on the used market; are they marketed more than others and simply outnumber competitors and/or are they not satisfying enough to the owners who purchased them (based on the following or curiosity)?  

I sold some less expensive Purist cables very quickly as you pointed out and was happy to do so since they did not light my fire in any way. YMMV

I have never dabbled with Cardas, but you are right, they do not seem to be flooding the market. Maybe that's a sign they are keepers more often than not?

@hilde45 - I'm yet to hear these speakers, but from my short time in this hobby they are spoken of reverentially. I'd love to hear speakers Devore some day. 

@rodman99999 - Makes sense. I'm in the same camp that once I find something that I'm happy with, I don't see myself changing things out. It did take some tweaking from my original purchases to get things "right" though. 

        Personally: Finding something that works well in my system(provides enhanced musical enjoyment/makes reproduction more realistic), insures it's retention.
