Amp for JBL L112

Hello

I am looking for a power amp to drive my JBL L112 (with titanium tweeters).
Maximum 1200$.
For now, I have the follwing options:
Phase linear 400 at 670$
Threshold S200 at 1140$
QUAD 606 at 650$
adcom gfa 555 II at 500 $
I know this sounds expensive, but these are the prices in France (I live there).
What is your advice?
which one is the most suited to my tastes (regardless the price) ?
which one is the best value for $ ?

My room is 30 m2 wide
I like controlled bass, large soundstage, defined but warm mediums and highs.
I don't like "hard" highs and mediums, (such as the NAD i ve been listening to)
I prefer a slightly warm sound (enjoyed the quad 405 mediums, but muddy bass)
I listen to jazz (lot of bass, drum, piano trios), latin jazz, 70's African music, roots reggae, electro and classical music. I listen at various sound levels. I don't want an amp that sounds well only at high levels.

Thanks for reading, hope someone has already compared those amps in similar conditions (espiecailly phase linear 400 against threshold s200)
