@JustAlex, if connecting your iMac to your 218 directly (assuming it has audio out), the Audirvana alternative is Amarra Luxe: which also includes Tidal integration.

There’s a free trial download, and, given Black Friday is almost here, there’s a substantial discount on offer - making it cheaper than Audirvana.
