market value of my gears


I possess the following amps and start thinking of selling them out. All of them in mint and original conditions. Just want to know their estimated market value at this moment.

A pair of Marantz 9 (Not reissue)
A Marantz 8b
A pair of McIntosh MC3500
A McIntosh 225
A McIntosh 240
A pair of Jadis JA200
A pair of Jadis SE300B

Thanks a lot.

Ignore 'blue book', not reliable and most of the time low ball pricing. Now for the comment on Nigeria. I buy all my equipment there. Never have had a problem, as long as you believe in virtual equipment.
Anyone who has acquired an exotic collection of ampilfiers such as this. And does not have an idea of the value? Is very questionable and should come under suspicion.
I'll wade in since I collect gear. You are one lucky person, all of your amps are quite collectable. However with collectable gear a large part of the selling price is dependent on the condition of the amplifiers, both cosmetic and functional, and how they have been repaired, upgraded, or modified. Without this information, no one can give you the slightest hint about the worth of your gear.
I am in Hong Kong and acquired my gears around 1996 to 1998. With my kids born later, I did have no space at home for hi fi set up. I shipped them to Vancouver. From that time onward, I never play them. Voltage of all of them is 110V. Just now, I consider to sell them but I am not in the market for 10 years, I don't know current market. So, I want someone help to point out where I could get info of current market value. Then I put them to public auction.
