I don't think so.
The way I see it, you're using power cables that soften and warm the sound, removing the room treatments and having no toe decreases the ratio of direct to reflected sound so you're hearing more reflected sound at higher SPL. I would also say you're adding noise via the AC line.
Further, replacing footers with specific wooden oak blocks and using carefully selected power cables and setup is simply another kind of tweak, it's NOT de-tweaking.
There's absolutely no doubt you can make the sound closer to what you'd typically hear live, I was just a show last night and listened from several different positions and unless you're near front row there is a lot more reflected sound vs at home.
So I get it, and I have no issue with it, I believe people should do whatever they want and achieve whatever sound they enjoy. However, I personally think this is not a de-tweak, it is simply a re-tweak and now it's tweaked MORE than before.
Saying this type of setup is more "natural" and "de-tweaked" is a very excellent use of language by ddk but IMO it's manipulative as who wants a synthetic-sounding tweaky system? Which is what you think you had before... laughable!
I also think we're conflating hearing detail on the recording, close-mic'ed by the engineer, that was intended for you to hear in a way you'd never hear live, and trying to make it sound more like you'd hear it live. Again, nothing wrong with this AT ALL, if you love it, I'm super-happy for you, but let's call a spade a spade.
Dave, I am describing what I hear in my system. You are describing my system without having heard it. I heard the fancy power cables before I toe-in my speakers. The speaker positioning to straight ahead was the last thing I did. The previous changes actually changed the sound more than the speaker toe-in did.
The Ching Cheng power cords and my stock Pass cords certainly sound different than the fancy audiophile cords. If you want to describe them as soft and warm sounding, I would describe the fancy cords as harder and cooler sounding in direct comparisons, but I would add that the fancy cords made the backgrounds blacker and the sound was less alive and breathed less. So, perhaps that is a preference thing. The former sound more like live music to me.
I agree about the reflected sound, and different recordings can sound very different based on mic position. I don't know much about it, but I do prefer sitting fairly close to live musicians, about 10' in a chamber setting, or seventh row at a concert hall. Actually, the sound in my room seems louder at the same volume setting without all of the acoustic treatments in the room. I guess there is less absorption and more reflection, but after careful speaker positioning, I don't seem to have many obvious room issues. (Al M. was actually quite surprised at how well the room behaved without all of the treatments).
These various changes combined have resulted in me hearing more differences between various recordings, not less changes. A close mic'd recording like the Sheffield Drum track or the RCA Appassionata is even more direct and energetic than it was before, and other recordings sound even more layered or distant than before. I did not write much about this effect, but the fancy cables, isolation, and room treatments actually made recordings sound more similar to each other than different. I actually think I am hearing more detail now, not less detail, though images are less outlined than before, and things are not as unnaturally spotlit and highlighted as they were before.
So, I guess you can describe this as more tweaked than before, but the bottom line is that I removed things, I did not add them. And sure, there is some fine tuning going on with my oak footers to balance the sound of my rack support, because in this case I am working with what I have and trying to improve the sound.
How we use language to describe what we are doing and what we are hearing is certainly a factor in all of this. And when it comes to the reasons for how and why these effects occur, I really don't know. I am not a designer and do not grasp the technological reasons behind what I am hearing. I am just trying to share my experiences without stepping on anyone's toes.
