.......on the Harman site if they're still available and if I thought I could get my money out of my S3100s.

I thought the 3100s sounded pretty good (better than the L-300s they replaced) but not outstanding. A lack of HF extension and so-so bass (these were not the series II versions with the upgraded crossover and HF driver). And ever since I replaced the carpet with hardwood floors in the living room the soundstage is smeared and the bass took a turn for the worse. As you can see I also have rather hard walls and no drapes. I was hoping the Ti's might fix some of that.

Any opinions on whether this would be a step up?

Is it realistic to think I could sell the S3100s in the mid $2K area?
