Rotel Unveils 3 Integrated Amp Model Refreshes With Upgrades
High-performance home audio components manufacturer Rotel announced model refreshes with acoustic and performance upgrades in three of its two-channel Hi-Fi integrated amplifier models — The A14MKII, RA-1572MKII and the RA-1592MKII.
The enhancements include advanced circuit designs and component level changes in key circuit locations, leveraging the design elements from the acclaimed Michi Series, the company said.
The A14MKII ($1,599.99 suggested retail), RA-1572MKII ($2,099.99) and RA-1592MKII ($3,199.99) include the acoustic upgrades and sonic improvements from Michi engineering that emerged from a three-year undertaking.
The A14MII is the new and improved top of the line model in Rotel’s 14 Series. The upgrades, built up the popular MK14, include a new Texas Instruments Digital to Analog Converter (DAC) supporting 32bit, 384kHz audio complimented by 25 component changes in the DAC output filters, the company said.
Power supply component changes were also made by leveraging design strategies from Rotel’s Tribute models. Additional changes in the signal path circuits provide “a richer and fuller audio performance” for realistic audio reproduction, the company said.
The A14MKII supports all popular source inputs including aptX and AAC Bluetooth for wireless streaming, PC-USB up to 32bit 384kHz, MQA decoding and rendering, analog, digital and a Moving Magnet Phono Stage.
The RA-1572MKII advances on the RA-1572 design with changes to critical circuits and component upgrades including a Texas Instruments 32bit, 384kHz DAC supporting PC-USB 32bit/384kHz PCM and MQA rendering and decoding. The company said 33 component changes were made in acoustic capacitors, filter capacitors and power supply render audio with a wider, deeper soundstage and improved accuracy and positioning.
The integrated amp supports a wide range of connections, and file formats including: a Moving Magnet Phone Stage input, XLR Balanced inputs, Coax input, Optical input, RCA conntacts, front iPod USB input and aptX and AAC Wireless Streaming Bluetooth connectivity.
As the flagship integrated amplifier in Rotel’s 15 Series, the RA-1592MKII outputs 200 Watts of Class AB power into 8 ohms and now delivers an even higher level of audio performance with upgrades to all critical circuits. The Texas Instruments 32-bit 384kHz DAC circuits feature 12 coupling capacitors with improved frequency response and even higher component tolerances, the company said. Upgraded capacitors are also used in critical signal paths. In total, more than 28 components changes were made with additional changes in the power supply circuits.
The RA-1592MKII source inputs include aptX and AAC high quality wireless Bluetooth streaming, MQA decoding and rendering via PC-USB, PCM PC-USB audio up to 32bit/384kHz, Moving Magnet Phono Stage, analog contacts, digital inputs, XLR balanced inputs and front panel USB for iOS device connections.
Rotel said all models feature Ethernet and RS232 connections for control system integration, IR remote, front panel status display, intelligent power control, Audio-Direct Tone Bypass mode and dual A-B 5-way speaker binding posts.
Each of the MKII models will available in a choice of silver and black at authorized Rotel and Sumiko dealers starting in May in the U.S. and Canada.
