Rotel RC-1572 MkII preamplifier & RB-1552 MkII power amplifier SET

RC-1572 MkII

Affordable high-end begins with Rotel’s RC-1572MKII Preamplifier including multiple acoustic upgrades and refinements processing your favorite analog and digital sources to an even higher level of performance in stunning clarity with a natural, enveloping sound stage.

As an essential component in a Hi-Fi audio stack the RC-1572MKII’s precision engineering begins with Rotel’s ultra-low noise power supply including a large, in-house manufactured toroidal transformer. The transformer design reduces stray radiated emissions and feeds a bank of slit-foil, low ESR capacitors delivering stable current to all sensitive circuits reducing noise and distortion with an ultra-quiet noise floor.

RB-1552 MkII

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.

Rotel engineering’s fanatical attention to detail means the sum is greater than the parts; this is what we call our 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 120 watt Class A/B amplifier features independent left and right power rectification stages and decoupling, and is essentially a mono block design. Further evidence of design over-spec 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.
