I am not sure that selling them is the right move as there are demo units selling at about 40% off retail, and a used pair will go for even less. The Arindal is supposed to be a magnificent speaker. It was launched in 2022 and I doubt they made very many of them, so you are fortunate to own what is now a relatively rare speaker.
Verity Audio have a reputation of being very reliable, and the American distributor has said that he would be able to help support any problems such as replacing drivers etc.
I remember reading that one longstanding retailer had sold many pairs over 1 to 2 decades and had never had a service issue.
I have had my Verity Audio Parsifal Ovation speakers for 14 years and they have performed flawlessly. I am in the process of looking for Verity speakers higher up the line, and have no hesitation doing so even though VA have gone out of business.
Enjoy the Arindals!
