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

[Multicore]

Thanks a lot!

I prefer quality over quantity, so I usually listen at about 75 dB on average.

It's challenging to take good pictures of my setup and room, but I do have a couple of drawings showing the overall layout.

I'll definitely look into drawing up the whole signal path as you did in your post.

I've been thinking of all those drapes and the sofa and imagining a red and white zig-zag floor.

Does the Roku 4 still get updates? Amazon is offering me one but I think it's a 2015 model.

Great to see all these various set ups.

Any reason to prefer that over the ultra?

It has optical SPDIF audio output. Some old Rokus like this have audio output. Newer ones have only HDMI, which, for some of us, leads to the problem of extracting the audio. So for example in my system, which has a projector and does not have either an AVR or a TV, I need an extra device to extract audio from HDMI and these things are not to be trusted, in my experience. It may have been involved in this nasty business. I don't like needing such things.

Don't use it often, I think so.

Am I wrong to assume the official curves are pretty good?

They are REALLY good!

In all fairness, this is for my given room and speaker position . Maybe I am lucky. But it is impressive to see how my subjective “wow, this sounds great” matches all known science.

We also know that stereo masks small frequency response irregularities. If stereo can do that, imagine what 89% reflected sound can do?

I strongly believe that a lot of the hate for the Bose 901 is sighted bias based upon the founder’s skin color (the 901’s were released when public school de-segregation was still a debate topic in Boston), the perception that they sue reviewers for bad reviews (not the case now that the details are available for modern review), and the performance of the lifestyle cube satellites.

I noticed that.

Hello ASR friends,

It is really great and amazing to see so many interesting setup "diagrams" during only five (5) days after I started this new thread on August 19 Monday.

Even though we already have several interesting "physical setup/connection diagrams of audio gears", only a few "total signal path diagrams" have been shared so far.
By "total signal path diagrams", I mean diagrams showing;
- the details of (your typical or optimal) DSP parameters (if included in your system and as far as you know!),
____including XO Fq, XO type (BW, LR, Bessel, etc.), low-side and high-side filter slopes, EQ Fq gain Q-value, fine delay on XO, invert or not at XO settings, output group delay in 0.1 msec precision, all the relative I/O gains, detailed routing, etc.
- where to control master volume,
- parameters in stereo and/or multichannel DAC (if any) including relative output gains,
- where to control relative gains among SP drivers,
- relative gain control in analog domain (if available),
- protection capacitors and/or any other protective devices (if any) for your treasure/gem SP drivers,
- parallel tuning-resistors (if any),
- normal or reverse (inverted) connection to SP driver(s),
- passive LCR network configuration (if any, and as far as you know),
- etc.

I believe such "total signal path diagrams" should be wonderful reference information not only for me but also for all the people on-board on this new thread.

Just for example, I believe the Fig.03, Fig.11 and Fig.12 in my very first post are showing almost all of these for your at-a-glance understandings. Please allow me pasting the three diagrams again here as follows;

You would please take your enough time and a little effort on preparation of similar "total signal path diagram(s)" to be shared on this exciting thread.
And, please let me also repeat this again;
I (we) do not always expect beautifully prepared/drawn diagrams and/or photos; even hand-written/hand-drawn rough sketch diagrams should work well in the perspectives of this new thread.

 

[DWPress]

you have way too much time on your hands.....

 

[TLEDDY]

WOW…just WOW!

Not only is the sound system awesome in and of itself… your images and presentation are simply mind-blowing!

Thank you for your efforts - truly appreciated!

Well it just goes to show that if you like to tweak, there are far better (and more fun) ways to enable that than buying new cables

Kudos for the diagrams - great work

this is mine, all diy except the turntable & minidsp:

In the spirit of @Sal1950's post very early in this thread:

ca. 1978. Loudspeakers were Polk Audio Monitor Series Model 7A. Still have all of it but the tuner and turntable (an adorable little Philips GA-308) -- unfortunately, I don't still have that RCA CTC-15 colo(u)r TV, either. Wish I did, actually.
PS The tuner was utter junk. It worked flawlessly but sounded pretty terrible. As John Dorsey of Soundscape in Baltimore said of it: "It's a collector's item -- and the collector comes every Tuesday!"

Spoiler

That'd be the garbage collector, for those who might be perplexed

I didn’t put the digital signal chain since that occurs in various black boxes (Apple Music and ARC3 mostly). But…

Scarlett 4i4 -> Mac Mini (master volume control, sometimes a source, and ARC3 does all DSP hosted by SoundSource)->Scarlet 4i4

Sometimes words are good. Our system has 2 channels. The speakers have the stock passive 3-way crossovers. The Flex preamp has room EQ. The WiiM gives user EQ to taste, but don't use any boost with that.

You aren't trying to slip anything past us here with this sotto voce use of rounded rectangles, are you?

Here's a diagram of the system. SDP-75 settings were tweaked after running the Optimizer but I still plan to have a professional calibrator adjust the system. It is a lot of settings, and specific to my system and room, so I am not listing them all here.
