Nice reference and truly new to me, so thanks for posting it. 🙂
@vacuphile,
Surely there might have been DC servos done with electrolytics, but I'd say that it's not the usual implementation.
Nevertheless, DC servos can have issues too; if one measure different gains depending if the the servo opamp is present or not, that might point why and where the reason can be.
Matt, Proof will be in if I can do it again......planning on incorporating Dirac into the new setup I’m pretty sure it tracks/charts phase and fr, impedance differences etc. so I’ll have tools at least to help show what’s going on as I dial in.
A neutral microphone for voice range can be found here ... beg, borrow or steal one of them -->

A good measurement mic will have lower distortion of all types than most any dynamic speaker.

My listening space is quite 'live' and I like it that way. I have a small carpet and a couch and that's it.
I don't understand those questions and controversies about "better", or "accurate" etc.
I don't know anything perfect in our world. So, what is "better" is just what we prefer.
Depending of our culture, the way we listen, the kind of music we prefer, the habit we have of instruments, the distances we usually listen to them etc. how could-it be the same for everybody ?
Even me, as a sound engineer, I was not at all in the same mood when I was in studios, mixing a live concert for PA, or even, mixing the same concert for producing a record.
By example, good monitoring speakers in a recording studio would be catastrophic to mix a movie and vice versa.
This said, I think I understand quite well what Markw4 is looking for, when we are talking of DACs and RNM when he talk of accuracy. I think they look at the same thing than me: Sharpness.
J.C. seems more interested by transparency and euphonics, of course, SW by performance, Bonsai by neutrality, Syn08 by its glory.
I cannot talk for all of us, apologize to the ones passed under silence.
Of course we all look in the same time to all those criterias, but with a different order of preference, what is obvious is that we do our best. ;-)
Love and peace in the magical Christmas spirit ;-)

Guys, this was a spoof post from me.
Spoof post. Its complete nonsense. The paper I linked to was some physics stuff I have no clue about.
I did it to have some fun.
However, the Mills MRA non-inductive resistor bit was not nonsense. I use a 10W device with Ayrton-Perry winding for the main feedback resistor in a big amp. Ultra low inductance, very low voltage coefficient etc. (You can see in my DIY audio designs up to 100W I use 5 0.5W MF in parallel usually - also very effective).
For 0.5W metal film resistors I use Xircon almost exclusively.
1. There was a plot put up on diyaudio a few years ago (I think it was a Swedish guy) where he measured the excess noise in a whole range of MF resistors and the Xircons performed admirably
2. Mouser carries a huge range of them - about 1.2c IIRC in qty of 100 up
So, good performance and readily available. I use Dales in some locations (preamp) but that's it.

Yes, because I think it should hold a margin of common ground for us and even be something to aim for if we want to come closer to the origin (I know it doesn't really exist)
If the origin was recorded well I see no problem with reproducing it as well.....Or well as possible. If that takes too much effort for some to worry about that’s fine but to say ‘I know it really doesn’t exist’ rather shuts the door to possibilities.
If your too hung up on ‘better’ than how about Best ! 😀

The equipment is accurate (speakers also not bad), but the speaker room interaction is always compromised IMV - especially if you are not listening in the near field.
I just prefer a very 'lively' sound.
