Brands that have the least depreciation

I agree about McIntosh.... maybe not for everyone but sure holds its value.  I bought a 5 year old C15 preamp locally for $700.... enjoyed it for 5 years and sold it on eBay for $1350...   

Classic  gear like Marantz, Mac and ARC.  Try buying a pair of Marantz Model Nine amps, or a Model 7 pre-amp.  Big bucks for sure. Take a look at what an ARC SP-3 goes for these days.

If we would have been smart enough to invest in, and stock pile these early editions back in the late 70's and early 80's, it would have been akin to collecting collector cars.

From what I’ve seen, Harbeth and Proac speakers will always hold their value.

Denafris Terminator Dac was sold at 4200$ last year.

Now the price got jacked up to 4,500$.

I found that used one listed at 3,700$ (US Audiomart)got sold within a week.
