I can only respond to the sound qualities of the Thiels. I own a pair of 22's which was replaced by the 2.3's. As people have stated, Thiels are very revealing. You will need a great source and tons of power. I originally ran my 22's with 200 wpc into 4 ohms. Granted it was with a Hafler amp, and the sound was not bad. Not harsh in any until you really open it up at high volume levels. Most people say Thiels do not play at high volume levels well. I made a small upgrade and am now using a Parasound amp rated at 400wpc into 4 ohms. What a night and day difference. I now have incredible bass. Bass that you hear even at very low listening levels. The biggest improvement is when I play my music rather loud. Absolutly no harshness. The sound is still sweet and smooth. Also noted, that I have my speakers in a room that does not have a concrete floor like most homes. My Thiels were spiked and sounded very nice. I added Vibapods under them and the improvement was amazing.
