I wish you could filter out anything you want. I would filter out dealer ads (for sure) and music, which clutters up the gear listings. I often have to scroll through pages of CDs and LPs that I would never want to listen to.
Agon is now a retail outlet.
This site has been taken over by retail outlets that also advertise on Ebay and other sites, posing as bargain outlets and asking prices that are close to retail for used items and raising the prices of older items to ridiculous multiples of their original prices under the guise of VINTAGE, when the items are often those that you wouldn't but in a thrift shop or pawn shop for more than 20% of retail even if you could find them since their rarity is based on the fact that Made In Japan was equivalent to what Made in China means today. To boot these items are old enough so that their capacitors and many other parts require replacement in order to remove the risk of fire from faults in their circuitry due to age. This is the reason there is no link to OWNER ONLY ads. Audiogon would lose much of their revenue from providing such a link.
