Selling gear made to be a set

Hello, I’ve recently decided to go all in on digital as well as trying to simplify my physical life, so I’m thinking of listing my Marantz KI Ruby amp and SACD player on here to sell. Before I do, I wanted to get some opinions on whether I should sell them individually or list them as the set. Ultimately, I don’t want to really deal with selling one without the other, but I’m not sure how buyers feel about that. I don’t think I would have a problem buying one or the other if I already had a piece I planned to keep. For example, if I had settled on a CD player, then I wouldn’t have a problem just buying the amp. My reasoning I think, is more for sale ability. What are your all‘s thoughts?
