The Rotel RA-1572 integrated amplifier (with inbuilt DAC and Bluetooth) is now available in Australia. It uses a conventional Class-AB output stage that’s rated at 120-watts per channel, both channels driven into 8 with THD of less than 0.03%. The analogue line-level input is specified as having a frequency response of 10Hz–100kHz ±0.5dB and a signal-to-noise ratio of 100dB (IHF-A) no matter whether you use the balanced (via XLR) or unbalanced (RCA) inputs.
As with all Rotel amplifiers, the RA-1572 features Rotel’s customwound toroidal power transformers along with custom electrolytic storage capacitors made for Rotel. ‘ The custom-wound transformers and power supplies are the foundation of each of their amplifiers, the source of all of the punch, clarity and headroom that these amps put out,’ said Leigh Fischer, of Interdyn, which distributes Rotel in Australia. ‘ It’s something Rotel is very proud of.’
The Rotel RA-1572 has coaxial (RCA) and optical (Toslink) digital inputs capable of 24-bit/192kHz performance, plus a USB input Rotel says can handle up to 32-bit/384kHz including DSD. It also has Bluetooth (aptX) so you can stream to it from compatible devices. The DAC is a 32-bit/768kHz AKM chipset. Users are able to fix the level and set an ‘auto-on’ option with the digital inputs to simplify operation and improve performance when using devices that provide their own volume control. It also has a built-in moving-magnet phono stage with a frequency response of 20Hz–20kHz, ±0.5dB and a signalto-noise ratio of 80dB (IHF-A).
Daren Orth, Chief Technology Officer for Rotel, said of the design process for the new RA-1572: ‘ We took the hugely popular RA-1570 and added a superior DAC, integrated Bluetooth, IP control and better amplification architecture—the result is our best mid-priced integrated amplifier to date.’ The Rotel RA-1572 measures 431×144×358mm (WHD), weighs 13kg and is available now in Silver and Black finishes. It sells for $2,499 (RRP). For more information, please contact Interdyn on (03) 9426 3600 or visit www.internationaldynamics.com.au
