The Revels are so good, they are a window to the amp and upstream gear. The Job 225 is absolutely amazing on my studio2. Just a little more forward than the Dartzeel and a little more energetic. Voice is natural but there seems to be a little more space between instruments and voices. I feel for my listening volume that I don't need more power. The Job 225 is fine. Amazingly articulate but the Dartzeel is a little smoother and maybe a little softer but not in a bad way or mushy. The Dartzeel is more natural. For my taste, adding a slightly warmer preamp to the job 225 would be a great combo. I am in shock as to how great the job 225 does on the studio2.
