Long recognised as a central component in superb yet cost effective music systems, the integrated amplifier’s job has evolved substantially as many music-lovers have migrated to digital sources. The RA-1570 is perhaps one of the best examples of melding proven analogue design with the most musical digital circuits to bring all of your sources to life with surprising, even surpassing, fidelity.

The RA-1570’s input section is substantially more flexible than that found in most integrated amplifiers. In recognition of the growing popularity of digital sources, this amplifier provides a front panel USB input for easy connection of a wide variety of music storage devices including Apple iPods®, iPhones®, and iPads®. Supported formats include MP3, WAV, and WMA files for maximum flexibility. In addition, real panel coaxial (RCA) and optical (TOSlink) inputs provide easy connections for LPCM music files with up to 24-bit word lengths sampled at 192 kHz. Analogue inputs include balanced XLR connectors in addition to conventional RCA jacks.

A Wolfson WM8740 stereo D/A converter with selectable digital filters handles critical conversion from digital data to continuous analogue waveforms. The Class AB output stage uses discrete devices to ensure precise reproduction of all signals regardless of origin with virtually any loudspeaker. The power output, a robust 120 watts per channel into 8 ohms, is substantial as it is a continuous “both channels driven simultaneously” rating fully in keeping with real-world expectations and Rotel’s tradition of providing real-world value.
