What do I need to complement the Thiel CS2.4

Have you had a chance to listen to them? If so, what other components were they used with? Knowing this would be the place to start.

Enero7...do you plan on using the 2.4s only for HT (i.e., surround sound for movies) or do you also plan on using them for 2-channel audio listening? If both, what % of time will you be uding it for one vs. the other? I ask because I own the 2.4s and love them but I don't really think they are optimal for HT applications in the sense that they don't do deep bass (but you can supplement that with a subwoofer) and while they are dynamic, there are more dynamic speakers out there. I think the 2.4s are a great speaker for music listening when driven with the appropriate amp but it would helpful to know what your intended use will be before moving on with the thread and getting relevant advice.

Cmalak,
My intention is mainly for listening music.
I would like to have a system that can get close
to listening live, like being in a concert (of course, you got to spend big bucks to reach to that level ).
But, just trying to get a good package of amp, speakers,...
so that they can produce a good sound. HT use is secondary.
My main purpose is to relax listening music with good sound
after a long day of work.
Thanks.

Also,
my budget for the whole system
is about 10-20 grants

I heard they like candy and Flores.
