Let me edit/add/update again:
- Revival of analog LP player (MC cartridge) in my DSP multichannel multi-driver multi-amplifier fully active stereo system for real time on-the-fly vinyl LP listening (and digital recording, if needed): #688 on my project thread

Please find the latest total system configuration with DIY 12-VU-Meter Array, the best tuned time alignment and Fq response, together with further various setup info as of May 30, 2022 here (post #540) on my project thread.

Please find the latest system setup and Fq response as of January 25, 2022 here on my thread.
On August 12, I posted and shared my present audio setup on
the thread entitled "Show us your audio setup!", but later-on the OP
@anphex suggested that all of the setup posts would be better to be moved into this thread.
Accordingly, please let me share my latest multichannel multi-amplifier stereo setup here on this thread again.
In
my multichannel multi-driver (multi-way) multi-amplifier stereo audio project, you may find the latest configuration and photos as well as the Fq response measured at my listening position in
my post here.
I hope it is allowed showing them again here for your reference, as follows;
As shared in my previous posts
here and
here on
my thread, the elevating Fq response over 7 kHz is intending to compensate my slight age dependent hearing decline; now the upward slope over 7 kHz can be easily, safely and flexibly controlled by YAMAHA
A-S301 driving STs on-the-fly, while listening to music, using the IR remote controller for
A-S301 from the sofa at my listening position.
Photos of the listening room;
And the distances;
Please refer to
my post here for details of the listening room environments.
The unique physical alignment of the super tweeters,
i.e. positioned under the woofers as described in
my post here, is really one of the critical factors in my system in terms of the 3D sound perspective (3D sound stage).
Present physical layout of PCs, DACs and amplifiers;
As for two of my DIY built audio dedicated Windows 10 Pro PC,
i.e. completely silent PCs, please refer to
my post here.
Edit:
One of the unique features of my setup is that I use four HiFi "integrated amplifiers", instead of simple "power amplifiers", dedicatedly/directly driving SP drivers. While keeping all the parameters in
the digital XO/EQ software EKIO and in
the 8-Ch DAC OKTO DAC8PRO, I (we) may
easily, flexibly and safely fine-tune the Fq responses on-the-fly (while playing music) by using volume/gain dials of these amplifiers, as shared in
my post here. The five volume/gain dials can be independently controlled by the five IR remote controllers while sitting on the listening sofa.
If you would be interested in my really intensive and long exploration on selection of these amplifiers, please visit
my project thread.
As you can find in above diagrams, I need so many SP cables; I use 600 V VCT (Vinyl Cabtyre) coaxial (twisted) flexible cables,
4-core AWG10 (5.5 sq mm) VCT (less than 3.37 Ω/km) outer diameter 16.5 mm and
8-core AWG12 (3.5 sq mm) VCT (less than 5.24 Ω/km) outer diameter 18.0 mm together with tin-plated copper Y-lugs for binding posts. See
my post here for details.
I very much carefully selected made of non-magnetic metals for all of the Y-lugs, R-lugs, connection terminal blocks (plates and screws) and binding posts, as shared
here,
here and
here. If we would accidentally use magnetic metals,
e.g. for a terminal block (metal plates and/or screws), it will deteriorate the sound by giving blur, low-resolution and uncleanliness to the sound quality.
I purchased audio grade non-magnetic terminal blocks (terminal strips) at a DIY audio pro shop. All of the plate and the screw are made of non-magnet metal. Although I sometimes feel a little bit frustration since I cannot catch the screw by magnetized screwdriver, it is really important to avoid any magnetic susceptible metals in these circuit to keep excellent Hi-Fi level sound quality.
Further edit on October 23, 2021:
Two of my audio enthu friends in Japan cordially contacted me by e-mail asking for backside wiring (jungle?) photos of PCs-DACs-amplifiers and also backside photos of SPs; they said that the photos would be better to be added in this post. Accordingly, let me add the following four photos here. I do hope the photos would be quite self-explanatory...
