Rotel Upgrades RC-1590 and RC-1572 Preamplifiers
Rotel has upgraded a pair of its preamplifiers to “deliver higher levels of acoustic performance”.
Rotel's RC-1590MKII and RC-1572MKII feature a host of acoustic and performance upgrades, according to the company. We are told that both of these well-respected preamps have had their acoustic circuits analysed and significantly improved by leveraging technologies engineered for the flagship Michi series.
Following in the footsteps of the recently renewed A14, RA-1572 and RA-1592, apparently 75 critical component changes have been made in the RC-1590MKII and RC-1572MKII. For instance, we can expect new coupling capacitors directly in the audio signal path to deliver improved frequency response in the DAC circuits which now travel via a Texas Instruments premium 32-bit/384kHz DAC.
The DAC power supply filter capacitors, volume circuit and XLR balanced circuits also benefit from resistor and capacitor upgrades, isolating the independent DC power supplies and resulting in a lower noise floor, says Rotel.
Additionally, both units support MQA and MQA Studio via the PC-USB input and are certified Roon Tested.
Both the RC-1590MKII and RC-1572MKII draw power via Rotel's in-house manufactured toroidal transformers, with the former sporting two that are physically and electrically isolated, providing dedicated analogue and digital supply voltages to all critical circuits. The transformer design reduces stray radiated emissions and feeds a bank of slit-foil, low ESR capacitors to deliver stable current to all sensitive circuits with reduced noise and distortion and an ultra-quiet noise floor, promises the manufacturer.
The upgraded models support balanced XLR inputs and outputs, Moving Magnet Phono stage input for turntable connectivity, analogue and digital source inputs, wireless aptX and AAC Bluetooth.
The new MKII models are available in both silver and black colours and priced at €1,949 for the RC-1590MKII and €1,299 for the RC-1572MKII. Shipping is expected around July 2021 with Asian pricing to be confirmed.
