The RB-1552 MkII is a stereo power amplifier by Rotel that delivers 130 watts x 2. It is a 2-channel design using a Class A/B output stage. Speakers connect via binding posts. A minimum impedance of 4 ohms makes it compatible with a wide range of loudspeakers. The Rotel RB-1552 MkII has an MSRP of $1,699.
There are 3 Rotel amplifiers in our database. Below you can see the main specs of these amps.
Rotel Power Amplifier Series
Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements. The Rotel RB-1552 MkII is rated at 130 watts RMS into 8-ohms. Rotel provides this wattage at a THD (Total Harmonic Distortion) of 0.03% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 130 watts into 8-ohms (20 Hz-20 kHz) at 0.03%
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)

Need more power?
Rotel RB-1552 MkII is rated at 130 watts into 8 ohms, which puts it in our 121 to 180 watts band. The next band up is Over 180 watts, which is worth about 2.3dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room. Plenty of systems are better served by the 91 to 120 watts band and better speakers.
When pairing the Rotel RB-1552 MkII with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
