Top resale value speakers

Keithr, while you have a point, it is rare or never that resale value considers inflation. Auto leases (residual values), real estate tax computation, etc are not affected by inflation indexing. Maybe in theory they ought to be, but for whatever reason they are not. Businessperson does NOT equal economist. So, while Elizabeth's computations may be 'flawed', it was done the same way as everyone else does it.

Note: just because everyone else does it does not make it right in every case. For example, spelling a plural noun (eg, kids) with an apostrophe (kid's) is not correct, even though every bloody one in my office seems to be doing it! Aaaaargh.

My best guess is of course the speaker I;ve been mentioning here for the past 2 months.
Tyler. Look at the amount of days it takes to sell a used Tylere. And then look at how many speakrers are on the gon for days and days, weeks even.
Most have like 30+ days on the market, not so with Tylers.

Is there a formula to calculate the accrued interest...by that, I mean the enjoyment provided, less the trouble [if any] caused by the speakers :-)

Well just to have the feelings of supreme elation at the sight of seeing SOLD in your ad is worth more than money. And then the experience of actual UPS pick up leaving your house, is yet another kicker
:-)

Harbeths are another obvious candidate. No such thing as a cheap used Harbeth.

Same goes for Sonus Faber, barring the entry level offerings. Exquisite cabinetry holds its value very well.

There seems to be an obvious relationship between residual price and not only quality, but also supply. This suggests that bigger bargains might be found with models from the larger manufacturers.

However concerns with resale value suggest indecision regarding choice. If that is so, then buying used as macrojack and others have suggested, seems the way to go to avoid heavy losses whilst experimenting with taste.
