On the subject of missing your systems so much that you want to find one equivalent while you’re traveling…Well good luck with that!
When I’m traveling I have Qobuz and Spotify and Tidal on my phone and iPad with a decent pair of wired or wireless headphones with also a decent pair of earbuds (Status Pro X) as less cumbersome gear.
When I’m traveling I’m immersed in seeing the sites, meeting new people, experiencing the local cuisine and at the end of my day, winding down relaxing and listening to playlists that I have created on the mediums described above.
For me, nothing replaces my home system’s quality of sound, but like @kennyc suggests, think portable systems for travel enjoyment and renew yourself when you return home. The important thing is listening to the “MUSIC”!!
