I recently consigned a phono stage with TMR and it was a good experience.
TMR Advised on pricing and gave me the choice of consigning the item or selling it to them outright. My equipment sold pretty quickly, and I had my money within a few days of the sale. The commission is pretty steep and maybe I could have made a little more selling it myself. It was worth the commission to me to know that once the equipment sold and I had my money it was done . Any hassle with the buyer, Shipping issues, etc., was not my problem. So, it was worth it to me and my experience was good.
