Audio valuations

The best way to find the real price is start high, and slowly lower the price until it sells. THAT is the right price.
Economic conditions, and good or bad luck may also intervene.
I mean if the item has one (or a few) person(s) looking for it, the item can sell at a higher than normal price.
If no one is looking for it.. Then it may not sell at all!

I had a Audio Research SP-10mkII I put up for sale here.
(I also had a SP15 which I thought was far better sounding, so off with the SP-10)
I got it cheap, and listed it for $2,200 at 7AM. Within thirty minutes I had FIVE requests to buy it... by 7:30 AM CST.
The going price was $3,000.
I was satisfied, I had no need to chase the money.

Patients timing and compromise 

I always look at hifishark and ebay's completed sales before I buy or sell anything.

elf1, you have been lowballed.  The 6b goes between $1000 and $1100 normally.

Lots of 6 series ARC preamps sold, and an active used market.  Audiogon's Bluebook lists them all, and eBay sales, Audio Mart, and other sites tend to agree with the values posted there.

This series goes approximately as follows:  6, 6a - $900-950; 6b - $1100-1200; 6c a bit lower, and the all-tube 8 around $1300-1500.

One of the lucky transactions that I actually made money on. This is the exception to the rule.

I just sold a pre-owned, discontinued mint SACD player for more than list because the buyer, who is very happy, has a large collection of HDCDs. At first he asked a ton of questions but then I realized he was serious.

(The new models won’t play them. Does anyone know of current production model that will play HDCDs?)

There are always lowballs out there but some folks stick to an unreasonable price. And there is fashion to contend with. I wonder if the prices of AJ Conti and Ayre equipment will go down drastically since the eponymous founder has unfortunately passed away?
