New listening room electrical design


I'm moving to anew house in a few weeks, and trying to figure out the electrical design.
My current room was designed by Rives and I have numerous dedicated lines in it, so, I'm somewhat familiar with the topic.
The new system proposed outline:
New dedicated subpanel, exclusively for the audio components (main located in the garage, adjacent to the new room).
I have 2 speakers (Avantgarde) with powered subs
2 separate JL Fathom subs
2 mono block amps (lamm ML2)
and number of front end component, locate on stand, that going to be on the side wall
(Preamp, crossover, TT and CD player)
I'm thinking:
Two lines with 2 duplex receptacles each to power avant-garde and JL subs
Two lines with one duplex each for Lamm mono blocks
Here is my main question:
For the preamp, crossover, TT and digital I have the following options:
1.   One line with two duplexes for the analog stuff
       Another line for digital
       3 duplex recptacles on 2 separate lines
2. One line (or two) and one power distribution box with 3-4 duplex receptacle, connected to the wall receptacle
3. Two lines hardwired (no wall receptacle and no IEC and power cord in the Power distr. box) to power distribution box, separating analog from digital receptacles inside the box

What is a better approach for the front end components?
Multiple lines feeding one duplex each,
One line feeding multiple duplexes
One line feeding power distribution box?

Nice problem to have 😀

I went through the same a few years ago. My advice would be to add as many seperate lines as you can be bothered with. Ideally at least a pair on each wall, well spaced to allow for future changes in equipment location. For the sources I always recommend a pair of duplexes from each line. Oyaide make lovely quad face plates to cover that duplex pair. For amps and others then duplexes are fine. I use SR Red and now black outlets but you can always swap these out to taste later.

As to isolating digital from analog I have better results using a power conditioner for all the sources and using the isolation in that, currently SR 10UEF with 12UEF on order.

Consider your source for in wall power cable. Top end would be JPS which I have used in the past but I recently used Synergistic Cryo treated Romex which is much cheaper and easier to use. 

Also consider installing an Environmental Protections EP-2775 ground filter and EP-2050 surge protector. I also installed a Torus 75A isolating power conditioner to drive the whole thing, I have used EquiTech balanced power on wall conditioners in the past as well
Power conditioning is used to solve a problem or solve a problem that one thinks they have. Power conditioning has a sonic signature just like everything else in an audio system. If you did install conditioning I would think having a way to bypass it would be desirable.

I know your new room is going to sound fabulous. I have used the Oyaide R1, SR Tesla Plex, PS Audio Premier, Furutech GTXD-Rhodium, and now the Synergistic Research Black outlets. The SR Tesla Plex outlets make perfect sense for the subwoofers. Once your system is up and running I do think it is worth the effort to compare your Furutech outlets to the SR Blacks. Especially since they are sold with a 30 day trial.

All the best for a satisfying system.

Be absolutely sure that all lines for your audio (& video if in same room) needs are on one phase.
