Rotel just announced acoustic and performance upgrades to three of its integrated amplifier models in the 14 and 15 Series product lines; the A14MKII, RA-1572MKII and RA-1592MKII.

The A14 is the flagship integrated amplifier model in Rotel’s 14 Series and the new upgrades include a Texas Instruments Digital to Analog Converter (DAC) supporting 32-bit, 384kHz 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. Additional circuit changes in the signal path circuits provide a richer and fuller audio performance with even more lifelike reproduction of the audio. The A14MKII supports all source inputs including aptX and AAC Bluetooth for wireless streaming, PC-USB up to 32-bit 384kHz, 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, 384kHz DAC supporting PC-USB 32-bit/384kHz 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 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 also adds the Texas Instruments 32-bit 384kHz DAC circuits, which include 12 new coupling capacitors with 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. Dynamic, controlled bass energy, exceptional detail and reproduction of every nuance of sound with exacting positioning ensure the innovations in the RA-1592MKII are deserving of the MKII designation. 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/384kHz, 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 five-way speaker binding posts.
The MKII models are available in both silver and black colors.
