Beautiful room and system.

Happy Listening!

Some components and speakers are also just more sensitive to changes.  I used to make virtually all of my cables (I probably have some of them in back-up systems and I have made them for others - didn't set out to do it but after they heard it, I agreed to do it at cost of materials).  Sometimes I'd make something and marvel at the difference it made in one system and then struggle to figure out why there was almost no difference in another.  Much of course depends on the room as well (it is so often the most overlooked thing).  I've had a one-third octave RTA for many years (and also now that computers have come so far I have Audio Tools on the Phone and iPads along with a calibrated mic as well as Windows 10 music servers in other systems with REW and a USB mic) and doing changes/movements in mine and other systems has helped me evaluate things better.  Of course everyone has different tastes and priorities as well (and there's nothing wrong with that).

For those who are interest in a more detail discussions of first order/time phase coherent design, I have just created a thread specific to this subject.  I actually have simulations, plots, graphs and not just subjective philosophical rubbish :-).

Personally I find it's a fascinating subject and hopefully I'll post some of my findings.  Just be warned, some of my findings may go against your belief (but not too much).  Tom may not like what I will say but ultimately we need to search for the truth.  Vincent van Gogh tried to cut his ears off but I don't think he found any.  Hopefully I won't cut anything off :-)

jafant - thanks so much for your kind comments (and thanks so much for your great contributions to this thread).  I noticed I had a few other comments on my system page (which I added not that long ago - and just includes the main system, I have other systems including speakers from Selah Audio, B&W, Ohm and GR Research and electronics in those secondary systems from Hegel, Mivera, NuPrime, etc.) and I have added a pic that shows a bit more of the room where the main system resides. I've also added some comments about what electronics are in the main system.  Don't post often as some threads are filled with comments not conducive to providing helpful information derived from actual experience (I do find some of it almost humorous and can't even imagine anyone even put any credence in someone who has no actual first hand exposure to something - this is a great thread where we have some wonderful expertise from various individuals - thank you all).

Andy - I'm interested in learning of your work and look forward to reading more on your thread.

As an observation of your opening statement, I read what seems like a false-start. I have followed John Atkinson's reviews, observations and attitudes with great interest since meeting him in the 1980s. Your semi-quote: "Since if a speaker can produce a step response correctly, therefore it is time-phase coherent, and therefore it must be "good" - is not something I hear him saying. He does say that "all else being equal, phase coherent speakers tend to produce exceptional imaging". (My semi-quote). I state and know that Jim would agree and think that John would agree that phase coherence (however measured) does not produce a "good speaker". I think that phase coherence (as an objective or success) increases the difficulty of making a good speaker by a large multiple, and that many attempts fail in many ways, including Thiel's attempts.

I look forward to your posts in your coherence thread and this one.
Tom
