We all have different opinions based on different tastes and experiences.
We have people who swear that the Paradigm Signature speakers are perfectly neutral and non-fatiguing, while some people say they wince when highs are being played.
We have people who say that the B&W 802D are perfectly neutral and accurate, while some people say they sound muddy and boring.
Who is the OP going to believe?
Who is right and wrong?
Zumbo says the MQ Quarts sound like the best speakers he has ever heard, and I believe him.
GranteedEV likes the EMP and the Salks, among others, and I believe him.
PENG says the B&W 802D is one of the best he's heard, and I believe him.
After listening to those speakers, I may not agree, but I believe that those speakers sound great to these guys.
And I'm happy for Zumbo, GranteedEV, PENG, and all these good fellas.

So when we make recommendations, as GranteedEV mentioned, we often like to stick to the basics because they are the safest.
And what are the basics?
As PENG, AJinFL, and others mentioned, We look at how the speakers perform in the lab - measurements like on-axis and off-axis frequency responses. There are other measurements, but these 2 are probably the most important as far as "neutrality" and "accuracy" is concerned.
Here is the measurements of the Infinity P360s:
http://www.stereophile.com/content/infinity-primus-360-loudspeaker-measurements
On-axis (Figure 3): you can see that in the important 200Hz - 15kHz, it is very, very flat!
Off-axis Horizontal (Fig 4): you can see from 300Hz - 10kHz, it is pretty flat from +/- 30 degrees. In figure 5, the vertical off-axis is also pretty flat.
"More important, note how evenly spaced the contour lines are in this graph, and how consistently the Infinity maintains its off-axis response across the audioband up to 9kHz or so. This means that the reverberant field generated by the speaker in a room will be as uncolored as the on-axis response. Again, this is impressive speaker engineering, even if you don't take the Primus 360's price into account. In the vertical plane (fig.5), the Infinity maintains its flat response over quite a wide listening window."
But like any other speakers, we have people who subjectively say the Infinity P362 is perfectly neutral and accurate, while some people subjectively say they are not.
The only thing I expect from a loudspeaker is that it can play the music clearly, instead of muddy and unclear sound. And if it can also play some tight bass, more power to it.
I also want to add that my brother used to own large Polk towers, and he thought the P362s sounded a lot clearer than the Polk.
Obviously the Infinity P362 is not the best sounding speaker out there.
I have auditioned the B&W 800D, 802D, & 803D; Revel Salon2 & M22; Paradigm Studio 100; Linkwitz Orion, Martin Logan Vantage; Krell Resolution One; Dali Euphonia MS5; RBH T3R/P; PSB Imagine T; Definitive BP7001, 7000, BP10B, & SM450.
I'm also in the process of getting a local KEF dealer in Edmond, OK, to borrow some Reference speakers from a KEF rep for me to audition soon.
I can say wholeheartedly that the Infinity P362 is a very clear sounding loudspeaker that can reveal more details than half the speakers I mentioned, can play better bass than a few of the speakers I mentioned, and has a better off-axis response than some of the speakers I mentioned.
The OP may want to try other speakers for under $1K, but I don't have the on-axis and off-axis responses of those speakers.
