I just bought a SP16 and a 150.2 and here is why. I was actually out to upgrade my Sim amp when my dealer had me listen to the above combo. Compared to the SimP3/W5 the ARC amps just sounded more musically involving, more relaxed. It reminded me more of how "live music" sounds. I have only heard two other ARC amps before so I can't really compare them to their older gear but I defientely like the amp in combination with my Dali speakers.
