What amplifier are you using? Without knowing how much power you have available, I could not make a good recommendation even if I was inclined to. For example, The Quad 22L's you site in your list have a sensitivity of 88 db/w and 6 ohms impedance and I know they require a good amount of power to really sing. Can you properly drive these?
Also, what is it about the speakers you have now that like and most importantly, don't like. Your Titus use a metal dome tweeter. Do you like this sound or did you find them bright? If bright, you may want to avoid other models using metal teeters and consider something more laid back, like a soft dome.
Buying used is OK but have some idea of what each might sound like beforehand. For instance, when I see the Quad 22L's or the B&W CDM-7NT's in the same list, I cannot think of two speakers that sound more different. How we know which is the sound that you prefer?
If you ask us, you run the risk of starting a popularity contest and will only find out what someone has or wants to have. And most likely, none of these will be the right speaker for you.
