I also liked the Dunlavy V, and owned Dunlavy Alethas for a while but sold them in favor of Genesis V, obviously a different technology and sound, especially in the space and air departments. If you're interested I gave my comparative impressions at AudioAsylum a couple years back:

Later sold the Genesis for Talon Khorus. The Khorus are different sounding than either, but meet, I think, your objectives of tight, tuneful, extended bass coupled with a smooth treble. Good detail is also there, but never in-your-face. Generally warmer and less dry than the Dunlavys, and easier with placement requirements.
Just another suggestion. Ultimately you'll have to listen for yourself.
