Is it possible to really know what you're doing?

I’d still like to know, if possible, who has claimed actually reached the bottom and what specific systems are so we could possibly use them as benchmark.  This is how we learn and grow, right?

The people who would claim this are typically the least trustworthy, and are inevitably trying to sell you something. 

People need a reference (and standard) in sound. So, they can start the audio from a standard point. And they know their goals. These points should be repeatable to everyone but no audio system is repeatable.

My audio system can be a standard and reference. It’s closest to the original sound, affordable, and repeatable.

Yes. I’ve reached the bottom. Those who reached the bottom, please post links your system. Showing a picture is no meaning in audio. Alex/WTA

Interesting philosophical comments throughout.

I guess my real focus was related to the technical aspects of audio systems. Given how complex these mystery boxes are, does anyone really understand what they're buying absent being an engineering tech savvy individual and there are many of them here on  this forum giving great advice.

I agree that a reference / standard needs to be established.  Former dictionary such as Oxford English Dictionary (OED) defines a stereo(phonic) system as a system of sound recording or reproduction using two or more separate channels to produce a more realistic effect by capturing the spatial dimensions of a performance.  So, imho, two keys elements defines a reference stereo system:

1. Realistic effect; and

2. Spatial dimensions.

In my pursuit of a reference audio system, I aim to achieve a setup that faithfully reproduces the tonal character (timbre) of instruments and voices with a high degree of accuracy.  This includes precise imaging—where each sound source is rendered with a clear, stable, and locational presence within the soundstage.  So, I were to lay out a specific metric for the reference system including:

1. Timbre accuracy;

2. Imaging; and

3. SS width, depth and height.

This metric may not be measurable instrumentally, but it can certainly be perceived in your listening space with a good pair of ears and a discerning mind. I believe you could always expand this metric to include many more elements you consider paramount. But bear with me for being simple-minded—and tell me, are you there yet?

It’s possible, but not many do. Have fun tweaking my friend and may the force be with you.
