For over half a century,
Rotel has been manufacturing award winning hi-fi components and for the last 18+ years, Audioholics has been there to cover their newest products. We continue this tradition with the release of the latest introduction of three new stereo components as part of the 1570 Series. We saw a complete overhaul of their Integrated Amplifier back in 2013 which we covered in our Preview of their RA-1570. It looks to us like Rotel’s newest version of the 15 series might be their best yet.
RA-1572 Integrated Amplifier
recognized 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-1572 is a great example of
melding classic analog design with contemporary digital circuits to bring all
sources to life.
of what we’ve seen of Rotel amplifiers, the RA-1572’s circuitry draws on a high capacity power
supply based on a Rotel custom designed and in-house manufactured oversized
toroidal transformer. As we’ve seen in the past, this design helps provide an abundance of voltage and
current for all operating stages. In addition, the transformer’s toroidal shape helps
prevent stray radiation patterns from corrupting audio signals as they pass
through adjacent circuit stages.
To help with the preponderance of digital sources
available today, the RA-1572 has a built-in 32-bit/768kHz AKM
digital-to-analog converter (DAC). The
DAC and surrounding circuitry supports a vast array of source inputs including
DSD capable PC-USB (32-bit/384kHz). A
front panel USB input is provided for easy connection of a wide variety of
music storage devices including Apple iPods, iPhones, and iPads and the Bluetooth input supports aptX.
In addition, two each coaxial (RCA) and optical (TOSlink) inputs provide
easy connections for LPCM music sources including popular streaming devices
with up to 24-bit…
