Yep, I am much happier with the DPS than the Astrodyne. Of course, to be honest, I only used the Astrodyne for a short time, before I talked to the tech-y at Headroom. At that time, I was paranoid that I had ruined the BUDA and was looking for anything that sounded at all off (which could have been in the recording I was listening to). Right now, I am listening to John Abercrombie's "Class Trip" (that I just picked up "pre-loved" at the local music store) on the BUDA+DPS+ECD-1 with the HD800's (balanced) and it sounds great - nice bass and drums.
