Does Audiogon allow borrowing equipment?

From time to time I see ads mentioning items for sale with trades possible in the transaction. I am not trying to buy or sell at this point (but may end up trading, buying or selling equipment during this process.)
Is it possible a post a question to borrow or swap equipment on Audiogon? I want to find a Frankenstein amp that I can hear in my home without having to buy one. I am willing to let the other party borrow one of my amps temporarily in exchange.
Is this against Audiogon rules?
