Recommend streamer that always works well with iOS Connect

[mwhitnall]

I share a problem many people have posted on concerning Marantz streamers working with iPhone Connect intermittently, i.e., the Marantz streamer often does not appear in the list of available devices. I have other devices (Gramofon streamers, Polk Omni speaker) that always work perfectly with Connect on my iPhone. I can always get the Marantz to appear on my iPhone Connect list of available devices by opening Spotify on my laptop and connecting to the Marantz - the Marantz then appears instantly on my iPhone list. However, I don't want to depend on my laptop to control the streamer with my iPhone. I have seen solutions to this problem where people fiddle with various things, but I'm not sure those are permanent solutions since it's an intermittent probem.

     So my question is: are there audiophile streamers on the market that always work perfectly with iPhone Spotify Connect? Even a recent Marantz model? (I have the Marantz NA6005.) I know it's possible because of my other devices.
