Have the Arc 160S. Love it. I would check with Arc or a dealer and ask that question. I will tell you that overall the ARC sound is warmer in general. I listened to a lot of amps for over a year before I decided on ARC and have never looked back. Rarely do you need to listen to more than 10 watts but I can’t speak for your room acoustics.
good luck and let us know how you make out!!
