I was considering the Dynaudio X12's but was told in another thread that they're at the opposite end of the sonic spectrum from my Grado's (which I assume means rather cool).
I definitely like warm; I returned the Grado SR325i's because they weren't warm enough.
Using a Marantz PM5004, Marantz CD5004, and Pro-Ject Debut III, and the Grado RS2i's.
I'm not too set in stone on budget, maybe around $800-1200.
