Key Features
The Rotel RA-1572 MKII is an integrated amplifier for Hi Fi systems. The RA-1572 MKII is designed to combine digital-to-analog conversion, preamplification, and power amplification into a complete unit. Pulling from their RB-1552 and RC-1552 models, the 1572 provides a complete experience, utilising a large transformer to prevent crosstalk between preamplification and power amplification circuitry to ensure a clean signal.
The RA-1572's converters are designed by Texas Instruments, providing 32-bit conversion and external output filters that enhance your favourite music's expressivity and detail. Meanwhile, the power amplification stage utilises slit foil capacitors, which store a lot of reserve energy for more dynamic musical sections and recharge quickly, creating a natural, energetic sound signature. This integrated amplifier supports a wide range of different audio connections and formats, including analog, digital, XLR, aptX, AAC Wireless Bluetooth, and Phono from moving magnet turntables, making it incredibly easy to connect to whatever device you need.

When it comes to choosing an integrated amplifier, sound is always the main priority. The RA-1572 MKII offers an extremely open, natural sound to send to your speaker system, making it the ideal pairing for most systems. Pair this with its ability to handle high-energy or dynamic material naturally, and you can be assured that every nuance of your favourite songs will come through clearly
The second key to a good amplifier is the assurance that it can connect to the equipment you already have, or play back your preferred audio codecs. Rotel have ensured that this is the case with the RA-1572 MKII, providing connections for analog, digital, XLR, and Phono cables, as well as aptX™ and AAC Wireless Bluetooth audio formats. Finally, for more simplified computer-based setups, you can connect to a computer via USB and stream pristine 32-bit audio with a 384 kHz sample rate with MQA support, which makes it easy to stream directly from services like Roon or Tidal.
Rotel have ensured that your signals will arrive at your speakers uncoloured and clear, thanks to their ultra low-noise power supply. Isolated by a transformer, your signal's noise floor is kept to a minimum. Then, the RA-1572 MKII's use of slit-foil storage capacitors help give its dynamic sound plenty of bass response and punch, and helps enhance your speaker's transient response. Complete with 32-bit digital-to-analogue conversion courtesy of Texas Instruments further enhancing its sound, the RA-1572 MKII balances quality components with efficient design to deliver great sound at an accessible price.
