wyred 4 sound vs odyssey khartago

I'm not familiar with either amp, but let me remind all that these particular Thiels; the CS 2's are not that difficult a load:
Thiels specs: 2.87 DB/2.83V/m, 6 Ohms nominal/5 Ohms minimum, 40-250 Watts/channel recommended.
Stereophiles measurements (keep in mind that Stereophile has been unable to test Thiels at Thiel's recommended listening distance): http://www.stereophile.com/content/thiel-cs2-loudspeaker-measurements

Francescof, please do let us know what you decide on, and how it sounds!
