I want to replace the router/modem Comcast with a high quality for streaming

I feel lucky to have found this thread.

Starting at the Basics, I am at present purchasing electrical cable for my home which is to undergo a substantial renovation.

My electrician friend assisting with the new electrics is aware a separate earthed spur is wanted for the Audio Set Up. 

The way things are unfolding, the Audio may be reduced to a Streaming Only arrangement, FLAC files and possibly a Hired Music Service as well.

What is the best options for me in relation to having Cable concealed in the walls?

How many wire runs is required?

Any info to help plan will be great. 

I was to follow up on the Cable Type, Run Requirement, with a question about Containment. 

I witness miles of Data Cable being Installed it is usually laid in a dust controlled environment and is usually concealed under a Metal Clad Floor Tile with Screening Properties?

I was to inquire if a metal conduit would have any benefits for routing the Data Cable? 

As strange as it might sound, this is a real Newbie on such an area of Data Transfer. 

How many Cat 6 or above Cable Runs is sensible planning? 

@bipod72 Am i correct if I read your post, with the interpretation, with the idea that I would be best to have two runs of CAT 6 or above Cable. With one of these being dedicated to the Transfer of Data for the Audio Only.

The main listening area for the long term owned audio system to be set up, is most likely to be an external of the home dedicated space, hence a digital only audio set in the remodelled home.

Would it make sense to run a separate feed again to the external of the home space, or extend an allocated cable run to be used solely for audio? 

I am acquiring all Cable Types for the project as an advance purchase, hence learning of the lengths I will need. 

New Investigation for myself. 

Fibre Optic vs CAT for Audio 

Being a Student is a place I like to be 👨‍🎓.

@bipod72 Thank You for the instruction, I will be making a provision for something that is working towards this type of set up.

This is an interesting area of conversation, as usually the Source Material for replaying recorded music comes of what can be described as an obsolete Hard Medium.

The Source Material that has Superseded the use of Hard Medium, is transferred as data (data packets) through the Internet.

The Internet is substantial in how it is used, and functions superbly for most needs,, but when it comes to supplying data that can be interpreted as a Quality suitable for Audio purposes, especially in the sub sector of Audiophile Quality. There is seemingly a lot to consider to ensure the data packets are able to be received as uncompromised as possible to achieve.

After reading a few methods for what can be done within the home, is there any things to be considered to ensure the data getting to the home arrives as a optimised date packet?

As I initially intend on producing FLAC Files to be used as the source material, I believe the upstream of FLAC Storage is addressed in the suggestions offered so far.

Streaming Source Material is not of the menu, it will be something that is evolved onto.
