I’m relatively new to this as well. I’ve been in the hobby about five years. My entire system was bought used, except my Lumin U1 Mini.
I mostly use USAudioMart. I have only had good experiences.
Suggestions:
- Read the buying guidelines/faq on USAudioMart. Also read the selling guidelines, and the scamming section. All useful.
- Check the seller’s rating, and look at their feedback history (what kinds of gear have they sold before? If you are buying an expensive piece of gear and they only have a history of selling cheap cables, I’d probably look elsewhere.)
- Ask the seller specific questions about the unit you want to buy. (Age, original owner, any issues, why did you decide to sell it, what accessories are included, etc.)
- Ask general questions (what other equipment they paired it with, what kinds of music they listen to, any recommendations about using it, etc.) Basically engage and get to know the seller personally a little bit.
- Make sure to solidify all the details and costs of shipping, insurance, boxing details, PayPal fees, etc.
- Make a reasonable offer. And if they accept then I always ask them to jump on the phone to chat. Usually just to say hi and b.s. about audio, where we live, etc. Just a chance to vet that they seem cool. And I have often met really nice people.
- You can also ask to jump on a call before you make an offer.
If anything feels off/strange, trust your instincts. Be patient finding the piece you want and the seller you want to deal with.
Good luck!
