Used equipment pricing advice needed

Hi All, Need some advise on what could be the possible price for some of the below stuff. All of them I can easily say cosmetic wise is above 8/10. All in good working order. Planning to let go.

Yourr feed back is very much appreciated, Thanks.

No one has any idea for any of the stuff above?

To determine prices of used stuff is a very personal thing. There are various factors involved which include condition of the particular component, brand name and seller's expectations to name a few. Some reputable audio sites like Audiogon have bluebook service which shows access to real-time resale values of popular brands.

My suggestion is you can set a price you are comfortable with for all your components. If they are not moving then either the market is bad, nobody is specifically looking at the listed items or the items are overpriced. Don't worry to much about it as if anyone is interested in any of your items they will enquire irrespective of what price you have set on them(unless you price them near to what you've paid for them in retail). You only need to worry on a few of those who are into low-balling.

Cheers.

Thanks ryder, will try to do some more home work and set some prices.

Okay, understood. All my stuff un-modified, heck most likely not even opened.

Thanks
