Best Computer Speakers
The best would have to be the Genelec 8331 or 8341 IMO. Very close to a point source with deep bass extension for the small size and 3-way design. 
Why I'm going to CanJam Socal
The highest rated IEMs in the $350 and under range at least according to Head-Fi’s big review threads seem to be the Periodic Audio Be and the Etymotic ER4XR. If you are open to open-backs, then iSine 10/20 are very well reviewed. 
Buy a pair of ten year old $40,000 speakers for $4,000 or new ones at that price point?
If I could get a 10 year old pair of Revel Salon 2s for $2,200, even with some scratches or slightly damaged cabs, I would take it in a heartbeat lol. 
Is the NHT xd System worth buying today?
XDa was a nice technical attempt to make a very neutral speaker using DSP but today I think with much better room correction software available for both powered speakers like GLM or Dirac Live for passives it's somewhat long in the tooth. 
Dealers and exaggerated treble
No, because the treble is above the room transition frequency. Unless you are in a tiny room with no porous surfaces (the walls are made of glass or something), the difference in treble should be from whether you are listening directly on-axis or ... 
Best Powered Monitors
Genelec The Ones are very, very good.The 8331, 8341, and 8351 are point source designs based on a 3-way coaxial driver system. 
Speaker of the Century Award Goes To ....
High frequency hearing acuity is almost irrelevant since 99% of musical energy is below 6KHz... 
Most “disappeared” speakers.
Omnidirectional speakers 
A little Patience sometimes pays off! (Kef LS50 content)
@yyzsantabarbara KEF is also Andrew Jones’ former employer, (he really gets around!) They have the Kef R3 and Reference 1. 
A little Patience sometimes pays off! (Kef LS50 content)
This is why Andrew Jones says the ideal bookshelf speaker is a 3 way, coaxial with a separate woofer. You get the imaging of a coaxial with the woofer handling the bass frequencies which are less directional below 200hz. 
Gamut RS3i vs. Joseph Audio Pulsars
I suspect the Kef Reference 1 will beat both of them ;)If you look at the Gamut RS7, which uses the same 1.5" tweeter and 7" woofer, they have the expected directivity issue with the huge FR hole at 2K due to using a 7" midrange driver. A 1.5" twe... 
Mating a SVS SB16 with a JL F113 v2 subwoofer?
I'm sure it'll sound fine, probably just look off from the decor matching perspective... 
Does anyone play two pairs of speakers at the same time?
Focal speakers BE tweeters are typically 27mm (1.125"), like Dynaudio's esotar which is also 1.1". It's a little more directional than a typical 25mm tweeter, which generally leads to a less "airy" sound since you have less reflections. 
Worth the wait? Buchardt S400's
Vocals being muddy is a general side effect of wide dispersion, if you want clear vocals that cut through everything you want a speaker that has a rise in 3-4k region and has limited dispersion so you are listening to a higher percentage of direct... 
Speakers under $50k that rival $200k+ speakers?
https://www.stereophile.com/content/tidal-audio-akira-loudspeaker I'd like to hear the Akira though. $70k in accuton drivers. Yeah, it's 215k, but if I was a 0.1%er I'd buy these.
