Kpede683, I had Dynavector XV-1s on my old Classic 1 but not on Classic 3 and have Lyra Atlas but on a different table so the comparison is exactly fair I would guess. However, I did hear XV-1s and Atlas on my friend's Classic 3 as well. Dyna was a bit more roll off on top, very musical, bass is a bit fatter,a bit slower, nice big midrange. Lyra is more open, more detail, on a leaner side but with excellent smoothness and a touch of warmth, more detailed bass. In my system, I personally prefer Lyra but then Atlas is almost twice the price of XV-1s. I have not compare similar price Dyna and Lyra though and I have not heard Delos or Kleos but heard 10x5 and 20X many times.
