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?

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.

Have been reading tons of the reviews on different AC outlets, and find reports to be quite contradictory.
Mainly, when reviewrs compare Oyaide R1 to Furutech RDX-D NCF, some say R1 are "warmer and musical" and NCF more "analytical", yet the others state exactly the opposite- R1 are "crisper with more leading edge" and NCF more "neutral".
I'm definitely trying to avoid anything, that could be perceived as "analytical, crisp, lean, having more leading edge" in my system, and now I'm lost about the choices, I need to make.
I actually ended up having a pair of each: Oyaide R1, Furutech GTX-D (gold) and Furutech GTX-D NCF (Rhodium).
I would do the following:

  • Get 2 or three isolated circuits, making sure ground was also isolated all the way to the panel, where they are tied together at the same place.
  • Get Pure Power AC regenerators
The PP Regenerators are active, and will cancel noise on either side of the outlet. That is, they will give you a pure 120 Hz input signal, and will correct for a lot of noise on the other side. They are designed by the same guy who owns Jansen Transformers. Really smart and nice guy.  They are very high efficiency and low impedance.  Parts Connexion sometimes has them on sale.

They do not however have any small units. I wish they had like a 200VA version (at 1/5th the prices) to run my DAC, BD and preamp from for instance.

Point is, they pretty much eliminate a lot of discussions and problems with outlets, wiring, blah blah.

Best,
