Save me a week of Roon research and answer my 14 questions?

A few clarifications on @Fernando_Pereira excellent response.

    1. Although many Roon users have their primary music files on NAS, IMHO, if you can have your files local to your MacBook, do it for all the reasons @Fernando_Pereira stated. Use the NAS as a backup of your files and to store backups of the Roon DB.
    1. Endpoints will sync in a multizone environment if they are using the same streaming protocol. All RAAT devices in a zone will sync with other RAAT devices. But RAAT devices can’t sync with Airplay, Squeezeboxes, chrome cast and Meridian devices. So if you want zones to sync, stay within the same family of devices.
    1. In general, the iPad and MacOS interfaces are the same. iPhone and Android interfaces are somewhat different due to the smaller phone form factor and some functionality is not accessible – primarily DSP. You can turn different DSP functions on or off in the phone UXs but you can’t configure them.
    1. In general, for transports, you need to decide if you’re a DIYer or not. If so Raspberry PIs are great. This is the most inexpensive way to go. If not there are literally dozens of choices of varying level of expense and capability.
    1. Roon supports Airplay so all older generation Airport Express’ work, but be aware of the multizone limitations noted in #3 above. You should know Airplay2 is not currently supported by Roon.
    1. I’m not familiar with Anthem Room Correction so can’t specifically answer your question on that. But Roon does enable the ability to attach a convolution filter to a zone for room correction and that filter can be built by tools such as REW, Acourate or third party services like Home Audio Fidelity. There is an excellent tutorial on room correction with REW provided by the community and many experts who can answer questions. You’ll find the REW tutorial here: A guide how to do room correction and use it in Roon
    1. No off the shelf supported way to do analog out with Roon. A few have gotten it to work as a bit of hacked solution… Turntable output to Roon
    1. Assuming you have iTunes match setup to maintain a local copy of your music files, point Roon to this directory and it will load all music within it.
    1. Do not think of Roon as a music metadata editing solution. Do any heavy metadata editing outside of Roon with iTunes or tools such as Yate or Metadatics (there are many users of both here and there are other tools out there beyond these). Roon does not touch your music files at all so whatever directory structure and tags you have will not be changed. Any metadata it brings to these files is stored separately. And if you do use Roon to edit metadata any changes will not be applied to your files but stored in the Roon db.
