There are other dealers that will ship you this as a new unit and send a "demo" invoice and give you a week to 10 days to demo in your home. If you like it then you buy it within those 10 days and keep it. If you don't like it then you ship it back. I do know that the Grimm MU1 is in tight supply for components due to the war in Ukraine. PM me if you are interested.
Fee for home audition
I am in the market for a music server/streamer. I was discussing with one of the authorized dealers for a streamer. He had a demo unit and was willing to bring to my home for an hour and let me try. He is located around 10-15 minutes from my home. He wants to charge 5% for home demo. Is this the industry standard? I am not meaning to disparage anyone so not going to name the dealer. I am just trying to see what the standard practice is.
