Overview

The RB-1552 MKII is a 130 Watt per channel class AB amplifier. It is engineered to be powerful and robust, yet able to extract every last nuance out of even the most complex musical score.

Rotel's fanatical attention to detail means the sum is greater than the parts, what they call the Balanced Design Concept. Each aspect of design is carefully considered holistically to result in maximum audio performance; from the selection of an over-sized power supply featuring a highly efficient, low magnetic field toroidal transformer to multiple, high-current bipolar output transistors. Circuit topology is planned, implemented, evaluated, and adjusted to achieve optimum results.

The RB-1552 MKII features independent left and right power rectification stages and decoupling, and is essentially a mono-block design. Further evidence of design overspec is in the selection of premium “slit-foil” capacitors, which provide plenty of reserve energy for extremely dynamic audio passages and are able to quickly replenish themselves due to the nature of their unique design. Input options are balanced XLR or unbalanced RCA connectors.

The RB-1552 MKII stereo amplifier has been engineered to provide high-resolution audio performance, yet it is very affordable, as has been the tradition with Rotel electronics for over 50 years.

Quality and Sonic Performance way above its price!

First off, thanks to Mel and Jeff for selling me this beauty! This amplifier is hefty and handsomely built! Rotel has a reputation for making high-end audio components at a price that most of us can afford and with the RB-1552 MK II they have earned that reputation! I have this paired with the Bowers and Wilkins 705 S2’s and my record collection has reaped the benefits of that union!

Wide soundstage, strong dynamics and no signs of fatigue at any point! It doesn’t matter whether I am listening at my favorite vinyl or watching the most action-filled movie, this amplifier recreates the sound in all its intended glory!

If you are looking for a power amplifier, go to Audio Advice and let tell you what you need to gain the same kind of audio nirvana I am enjoying now with their highly recommended Rotel RB-1552 MK II.
