Sorry it really wasn't my intention. My apologies. I was just asking about an audio thing that I didn't know much about, and I'm still not that super sure why it got heated. I think I offended the dignity of audio, which makes sense, I'm no expert.

I'm willing to accept that I made it weird; that's fine. I'm just trying to enjoy a 4 day weekend, promise!

I honestly don't know. Sounds from everyone's opinion like it's a total waste of time. Super fair. I really do appreciate the feedback and had zero intention of... doing whatever just happened there. Thank you.

I totally get that there are much better speakers than the 530s, for sure, but they just speak to me for some reason. I've had way objectively better speakers, but the 530s are super, super fun, and me being a layman, I have literally zero idea why. But you make a good point; the speakers aren't anything objectively special so why do I care regardless? Good question.

It's honestly really hard for me, a layman, to understand what's real about audio and what's fake. Maybe I'm just stupid, but there's a lot of fluff out there and it's super hard to know who is spitting actual truth and who is... well, not. Ultimately I'm just trying to have a little fun and hopefully make my stuff sound better. Whether that's possible or not is unclear. I'm more than willing to agree when I'm wrong or out of pocket.

I know you feel attacked. Do you understand that you are in a thread that is made to make fun of people who do things like you are doing? That's why this is happening.

You want advice here? Buy things that you can afford. Buy cables that are sturdy enough to withstand being plugged/unplugged, or get sturdier ones if they're going to get stepped on, etc. Don't try to mod gear unless you understand the underlying principles of the mod. If you want advice then there's an audio questions thread that isn't designed to make fun of people who believe in magic or try to justify spending 10x what is necessary for good sound, or don't measure outputs.

Here's a few very broad guidelines that I follow. Others may disagree or have more to add.

In reviews, look for objective measurements.

If the sound of a component is described using words more typically used for weather or food, be wary.

The law of diminishing returns always applies.

Assuming they aren't broken and not counting build quality, cables are cables.

1s and 0s are 1s and 0s.

If a big name musician is pushing a technology that promises better sound, it's probably a safe bet it's bullshit.

The 530 and A07 measurements are both pretty good, there is an objective reason you like your setup. If you want to take it to the next level, get a MiniDSP Flex with a microphone and DIrac license. Your A07 will do just fine hooked to the outputs, and it’ll make your 530’s sound even better.

For whatever it’s worth, I used to use an A07 to power my Quad electrostats (ESL-63’s) and B&W PM1’s and it was totally fine.

Went with the B&W 702s and the bigger of the two centers and I'm in heaven so far. Still need to fart around with placement and run Audyssey. They're rear ported so I should probably try pulling them out a bit more from the wall and experiment with some toe in.

Also thinking I might get some B&W DS3s (dipole/monopoles) and upgrade from 5.1 to 7.1. My last house the room wasn't big enough for 7.1 but this one it should work nicely.

So is the entire concept of “soundstage” audioquackery? If not:
What’s it referring to exactly and how is it legitimately measured or what are the adjectives that should be used to describe it.
Is it only to do with speakers?

If it’s real, then it sounds fake. But I’m not an audiophile, real or ridiculous.

It's not quackery, it's basically how instruments sound around you, similar to surround sound in a movie (hence Dolby making moves in the space recently with Apple and the spatial audio stuff). How a lot of audiophiles talk about it however....

Okay, okay, some real info: out of the box they're great for movies but to get them good for music (not absurdly boomy) you need to either stuff the ports or set the crossover super low. I did the latter and set the crossover at 50hz. I kept my SB12-NSD in to fill out the space between 50 and 100 and it works great.

If it’s real, then it sounds fake. But I’m not an audiophile, real or ridiculous.

There’s always some debate, but ‘soundstage’ beyond the recording itself is generally associated with perceptual acoustic metrics such as “Apparent Source Width” and “Lateral Fraction Coefficient”.

Without getting too deep into the maths, these values are calculated at various frequency ranges from a combination of a loudspeaker’s own impulse response to a given input signal, and the room’s separate impulse response to the same signal. You need both an omnidirectional and a figure-8 or dummy head binaural microphone for some of them.

For loudspeaker assessment this is typically qualified by the “early reflections” metric on CTA-2034 standard “Spinorama” data. It’s an indicator of how much sound from the speaker will hit the walls and ceiling in a ‘typical’ listening space, and is based on fairly extensive research and listening tests conducted over some 30 years by Floyd Toole and Sean Olive.

Short summary: not all reflections are bad, so long as they generally affect all frequencies equally.

We don’t generally enjoy listening in an anechoic room (trust me, I’ve done it quite a lot).
A speaker with consistent frequency response at various listening angles is generally preferable to one that sounds amazing directly in front of it, but has big peaks and dips in the response when you move off to the sides or above.

To generate these plots you need anechoic measurements at multiple positions around a loudspeaker. The associated AES standard calls for 5 degree resolution in a full balloon, but points may be skipped if the speaker cabinet has symmetry planes.

A decent primer on loudspeaker measurements is available here:
https://www.audioholics.com/loudspeaker-design/understanding-loudspeaker-measurements
And for Spinorama data specifically:
https://www.sausalitoaudio.com/wp-content/uploads/2018/07/Interpreting-Spinorama-Charts.pdf
https://www.psaudio.com/copper/article/choosing-new-speakers-using-spinorama-part-one/

Unfortunately it takes quite a bit of practice and experience to be able to understand what most of this data actually indicates or means.


A few reviewers publish this data, but it may only be generated from horizontal and vertical plane data every ten degrees. There’s a couple of German magazines, some bigger ones like Stereophole, etc. You can trust anything with Anselm Goertz in the byline, and there are two ‘independent’ guys - Erin & Amir - with a very expensive acoustic holography measurement tool called a Klippel NFS that publish their own data on either the AudioScienceReview website or Erin’s Audio Corner website.

Be warned that reading the plot first - or even seeing the physical speaker or brand name - has been proven by the same guys (Toole & Olive) to massively influence the subjective assessment of a loudspeaker. Unconscious bias works both ways.



There’s more to it than just this plot, of course. Issues like poor temporal alignment of each transducer, intermodulation distortion (where one cone makes another move, or a single cone starts to ripple instead of moving like a piston), and the like.



If you’d like to read more about this sort of stuff, Toole’s book is a great place to start. It’s got lots of diagrams and relatively plain English explanations about all sorts of perceptual sound stuff, with lots of practical advice that should help prevent you spending obscene amounts of cash on bullshit:
https://books.google.com/books/about/Sound_Reproduction.html?id=tJ0uDwAAQBAJ


Obviously, there’s a bunch of folk who seriously hate this work. Common complaints are that it’s based on ‘only the majority of people’ rather than trained listeners. There are absolutely clear distinctions between trained and untrained listeners in all sorts of research data, but as ever confirmation bias also heavily exists in all sorts of folk.

Magic, got it :D

No for real, even though I may not have understood all of it, I now understand more and appreciate it.

So, throughout all of this measurement it seems that environment plays a huge part. It’s awesome that some people are fighting the good fight and trying to get empirical data on something with so many variables. Easy mode would be to hold the environment perfectly stable as a control, but you already mentioned that anechoic chambers won’t give very accurate results regarding how good something sounds. What a tough nut to crack…

Question: what’s “temporal alignment of the transducer”, something to do with the voicecoil?
And what’s a “full balloon”, lol

You need audiophile level carpet. Some carpet will mute the natural airiness you'll get from classical music or that twant from a hi-hat in rock and roll. Really you should have separate carpets for the type of music you want to listen to. Everything in your space is really important to how your space sounds.

So you're really going to want the carpet that's going to give you the most lunch from your low end and higher end frequencies while muting the mids a little, but still carrying them. I'd avoid stain master as the coating really doesn't give you this. You're better off with carpet tile from my experimenting this is the best.


I'd avoid any kid of drapes because you want to avoid Windows as they can really gently caress with resonance at the end of the frequency tail.

You need to take the carpet to the forest, cover it in dirt and dead animals, leave it for a month, and then bring it back to your listening room. Any detritus that can't be brushed off will help expand the soundstage and really let you feel the low end frequencies. The scent and motion of any fungus or small animal infestations enhances the feeling of dread you should already be getting, plus it'll diffuse some of the sharper treble notes, especially when it comes to hi hats.

The important measure is "does it sound good enough that no audible flaws can be heard?".

Basically every AVR will show bad SINAD numbers, but I'm perfectly happy with my Denon, because the room correction and bass management more than make up for a slight deficiency in SNR.

Yeah, absolutely. And there's the point that sometimes he's all HIGH NOISE FLOORRRRR but then it's about -96dB and it's just... so what? It ain't audible. I live (like many people) in a small house with people through the walls and cars outside and aeroplanes and wind noise from trees and poo poo, and I'm willing to bet that 70% of the stuff that gets a LOLPOOR rating from the ASR fanboys I would never be able to hear a problem with because of the ambient noise floor and the fact that I don't listen to things at particularly loud volumes anyway.
