Let's share diagrams (and photos) of our total physical audio system and the whole signal path, with a few words and/or links

I just opened a new thread about the purification of my System: https://audiosciencereview.com/forum/index.php?threads/gaya2p-the-purification-completed.63700/

Thank you for the link to your amazing new thread!
I (we) can understand the title of your new thread as having "Purification" with capital "P", or even "Purifi-cation".

Dear @dualazmak , thank you for this thought provoking remark. I am contemplating now on whether Purifi-cation is the better choice for capturing my process.
Listening now to the layest album of Keith Jarrettt : New Vienna
It helps in the contemplating process ;-)

As of today, I use a 3.1 channels Hi-fi set-up as such:

This set-up is laid out in a 47 m² living-room:

There is 2.78 m from left to right speakers axis and the listening area is at 4.17 m.

The ceiling has been lightly treated with polyester fiber absorptive tiles to cover about 30% of its surface. The tiles cover the entire area of the primary reflections and are randomly placed elsewhere.

Further works will involve increasing the number of available 2.0 sources by hacking the multi-room feature of the Linn preamplifier, expanding the number of available front channels to 5 and completing the acoustic treatment of the ceiling with diffusing clouds with integrated lights instead of the current lighting.

Very interesting and impressive setup with center SP and two subwoofers in addition to the main L&R SPs!

I noticed that two Cabasse Etna2 subwoofers (L and R channel if I understand correctly, or L+R mixed mono?) are placed behind the center SP in rather narrow L to R distance, right?

Even though I assume this setting would be your optimal physical subwoofer alignment in your room acoustic, have you ever tested placing the L and R subwoofers rather farther away, say just outside (or just inside) behind the L and R main SPs?

 

[Scytales]

The two subwoofers are in parallel on the same channel and are in use only when an LFE signal is present, ie with 5.1 music discs and, of course, 5.1 movie soundtracks (I occasionally move a widescreen monitor in the living room from time to time to watch movies).

Before I went multichannel, I used to use the two subwoofers separately, one for the left channel, one for the right channel. The Cabasse Polaris AM1000 also includes an active filter stage that is switchable in low-pass or high-pass, specifically designed for bi-amping. At that time, each subwoofer was placed the closest possible behind its associated tower speaker. Even earlier, I had only one sub and the bass from the R/L channel was summed in mono. The configuration with stereo bass proved to be much better.

Keith Jarett!
What a miracle coincidence, I too was much enjoying Keith Jarett's wonderful classical music performance today Sunday (here in Japan) afternoon.

Only if you would be somewhat (or a little bit) interested in classical music, I like to suggest you would please listen to Keith Jarrett's wonderful performance of "Händel: Suites for Keyboard" CD ECM 445 2982 recorded September 1993 at State University of New York, Purchse.

Not only the authentic (my best preferred) performance of Keith Jarett but also the recording quality of this CD is amazingly superb, and I included one of the tracks, Track-3 Suite HMV 452 G minor Sarabande in my "Audio Reference/Sampler Music Playlist"; please refer to my hosting independent thread entitled "An Attempt Sharing Reference Quality Music Playlist: at least a portion and/or whole track being analyzed by 3D color spectrum of Adobe Audition" and the specific post here #590 "[Part-02] Solo Piano Music:" which has YouTube link to the whole CD album. His notes/article in the CD booklet is also very much impressive and informative.

If you would be interested in this album, I highly recommend you purchasing the CD for better sound quality and for "sincere respect" to keith, even though you may find other high-quality streaming distribution of this wonderful album.

I actually have five CD albums of "Händel: Suites for Keyboard" performed by five pianists on modern nice pianos, and I like Keith's album/performance best because of his authentic "in-steady-tempo" and "still-with-sublime-lyricism" with little deliberate-out-of-tempo, with little uncomfortable-ornamentation.

Thank you for your quick response which I understand well and essentially agree with you.

Just for your (and for other people onboard on this thread) possible interest and reference, let me share with you my following posts regarding L&R subwoofers (in stereo) in my multichannel setup;
- Excellent Recording Quality Music Albums/Tracks for Subjective (and Possibly Objective) Test/Check/Tuning of Multichannel Multi-Driver Multi-Way Multi-Amplifier Time-Aligned Active Stereo Audio System and Room Acoustics; at least a Portion and/or One Track being Analyzed by Color Spectrum of Adobe Audition in Common Parameters:
[Part-01] Full Orchestral Music: #588
[Part-03] Typical(?) Smooth Jazz Music with Guitar: #591
[Part-08] (Smooth?) Jazz Trio: #640
[Part-09] Organ Music: #641
[Part-14] Piano Concertos: #650

- A nice smooth-jazz album for bass (low Fq) and higher Fq tonality check and tuning: #63(remote thread)

- Reproduction and listening/hearing/feeling sensations to 16 Hz (organ) sound with my DSP-based multichannel multi-SP-driver multi-amplifier fully active stereo audio system having big-heavy active L&R sub-woofers: #782

Actually i do listen to Keith's classical work as well like his Handel performance of 1993. My taste for music is mainly classical, jazz , blues and by occasion pop. The key parameter is: can i hear the musician, a peek into his/hers soul so to speak.
