Which Kharma?

Hi all
Hoping to get some input on which Kharma model to get
I have Tenors monos and Amati now, sound is good but I do think Tenors straggling a little specially at high volume,
my budget will be only 10K so it will have to be used pair.
I did audition 3,2F it is great speaker but just little short in bottom octave specially compare to Amati. I was thinking about 1,1 or 1,2 also seen some 1.0 advertise on Adiogon.
My set up consists of VPI HRX Aesthetix Sig phono, ARC Ref 2 mkII preamp.
Many thanks to All in advance!!
Andrew
