Rotel has announced acoustic and performance upgrades to three of its integrated amplifier models in the 14 and 15 Series product lines. The upgrades include circuit design innovations and component level changes in key circuit locations, leveraging the design elements from the Michi Series. The A14MKII, RA-1572MKII, and RA-1592MKII are the recipients of these acoustic upgrades and sonic improvements.
The A14 is the flagship integrated amplifier model in Rotel’s 14 Series. Building upon the A14, the new A14MKII upgrades include a new Texas Instruments digital-to-analog converter (DAC) supporting 32-bit, 384 kHz audio complemented by 25 component changes in the DAC output filters. Power supply component changes were also implemented leveraging design strategies from Rotel’s Tribute models.
The A14MKII supports all popular source inputs, including aptX and AAC Bluetooth for wireless streaming, PC-USB up to 32-bit, 384 kHz, MQA decoding and rendering, analog, digital, and a Moving Magnet Phono Stage.
The RA-1572MKII has been engineered from Rotel’s RA-1572 integrated amplifier with critical circuits and component upgrades including a Texas Instruments 32-bit, 384 kHz DAC supporting PC-USB 32-bit/384 kHz PCM and MQA rendering and decoding. Over 33 component changes in acoustic capacitors, filter capacitors, and power supply render audio with a wider, deeper soundstage and improved accuracy and positioning.
The Moving Magnet Phone Stage, XLR Balanced, Coax, Optical, RCA, front iPod USB, and aptX and AAC Wireless Streaming Bluetooth input connections ensure support of all popular sources.
As the flagship integrated amplifier in Rotel’s 15 Series, the RA-1592MKII delivers 200 watts of Class AB output 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, 384 kHz DAC circuits feature 12 new coupling capacitors with improved frequency response and even higher component tolerances. Upgraded capacitors are also used in critical signal paths totaling over 28 changed components with additional changes in the power supply circuits.
The RA-1592MKII is replete with source inputs, including aptX and AAC high-quality wireless Bluetooth streaming, MQA decoding, and rendering via PC-USB, PCM PC-USB audio up to 32-bit/384 kHz, Moving Magnet Phono Stage, Analog, Digital, XLR Balanced, and front panel USB for iOS devices.
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.
The MKII models are available in both silver and black colors.
