Product Description 

The heart of an uncompromising audiophile stereo “separates” system is the preamplifier. Separate components hold the promise of the best possible fidelity, since each device is optimized for its role in the sound reproduction chain. The new RC-1572 stereo preamplifier leverages the design of our flagship RC-1590 preamplifier including its 32 bit/768kHz AKM stereo digital-to-analog converter to handle critical signal conversion. Among many refinements, the RC-1572 utilizes relay switching for analog sources instead of an IC based switch to maintain the integrity of the signal path for RCA, phono and XLR inputs.

Beneath the clean lines and user friendly fascia of the RC-1572 lies highly sophisticated engineering. Both analog and digital sources have been given equal consideration as today’s listener often has several digital sources, but may also enjoy legacy formats like vinyl LPs. A large toroidal transformer and regulated power supply ensures stable current and voltage requirements to all stages under dynamic conditions. Premium circuit components have been selected only after extensive listening evaluations. Careful routing of all low level signals has been practiced to ensure impressive signal to noise levels. The result is effortless musical dynamics, impressive detail and scale.

The RC-1572 stereo preamplifier is also extremely flexible. Four digital inputs (2 coax and 2 optical), plus the rear PC-USB handle digital sources up to 32/384 resolution. The 4 inputs are designed for sources such as TV set-top boxes, flat panel TVs or Blu-ray players for stunning playback. Importantly, it is possible to fix the level and set an auto-on option with digital inputs for use with devices that provide their own volume control for convenient “hands-off” use.The PC-USB input supports DSD signals. Integrated Bluetooth aptX is provided. Analog inputs include balanced XLR connectors, perfect for connecting the RCD-1572 via its XLR outputs, in addition to four pair of conventional RCA inputs. A moving magnet phono stage rounds out the source capability. XLR and single ended outputs are provided along with a mono subwoofer output, as are two 12-volt triggers to control on/off operation of an amplifier and/or other components. For custom integration, control options include RS232 on a standard DB9 connector, as well as an Ethernet port for IP control and software updates. In short, the RC-1572 is a tremendous value and the perfect upgrade for owners of older analog-only preamplifiers.

RB-1552 MKII

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. 

Notable features of the amplifier include independent left and right power rectification stages and decoupling. The layout 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.

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.
