One...Taylor at Goldprint Audio. He is great to deal with, not pushy, he's knowledgable, does setups in his home office (when it's safe), has driven miles to meet me to deliver an item (we are ~75 miles apart). I have a more local audio dealer who I shall not mention who is miserable to deal with, so I stopped in 2008.
How many dealers do you use?
When buying gear retail, do you use only one dealer with whom you develop a relationship, or more than one?
