Hi atriya, I will give you some input as I am/have been on a somewhat similar journey as you. I have had a couple of the speakers on your list and use some LTA gear.
The clincher for me out of all the speakers I tried so far were the Neat Petite’s.
Here is my list of nearfield speakers I listened to or were on my list: Neat Petite Classic, Dali Menuet SE, Philharmonic True Mini, Ascend Acoustics Luna V2, Harbeth P3-ESR XD. Elac Carina, Source Speaker 1.5WCA, ATC SCM7, ProAc Tablette 10, Audience 1+1, JMR Folia Jubilee, Physics Audio, Sonus Faber Lumina 1
Of everything that I have tried, this is what sounded best to me for a nearfield setup: Chord Qutest DAC, LTA MZ3 preamp/headphone amp, Orchid Audio GAN monoblock amp, and Neat Petite speakers.
My current setup is: Qutest, LTA Z10, and Neat Petite speakers. This setup sounds good at low volume but runs out of drive/headroom at higher volume. But, oh my, the Z10 with upgraded tubes is glorious as a headphone amp.
Speakers I tried: CSS P215, Omega Baby Alnico Monitors, Focal Aria 906.
If I just listened to Jazz the Omega’s were wonderful. The Focal’s were just too big and I didn’t gel with them.
I have the KEF LSX II’s for my wife in our office. I will say they are super versatile, convenient, and I am amazed at what they can do.
