I thought y’all might find this interesting: I just sold my HD-650 on eBay for $20 more than what I paid for them new in 2017, and $70 more than the MSRP of a 6xx. I had feared that the advent of the 6xx would have pushed down the prices, so I was expecting to sell for somewhere south of $200. I’d like to think this should encourage people who might be thinking of taking the plunge, people for whom roughly $300 is a big step: If you don’t like it you will be able to get your money back.
The poor guy probably thought 650 has some magic that 6xx doesn’t have. Audiophilia snake oil, I guess.
Who am I to fill him in?
