Rotel’s Integrated Amplifiers Announced as Mkii Models Leveraging Michi Technology

The following is a press release issued by Rotel.

Tokyo, Japan | April 2021 – Rotel is thrilled to announce acoustic and performance upgrades to three of their award-winning 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 acclaimed Michi Series.

The A14MKII, RA-1572MKII and RA-1592MKII are the proud recipients of these acoustic upgrades and sonic improvements built from the Michi engineering efforts that were 3 years in the making.

The A14 is the flagship integrated amplifier model in Rotel’s 14 Series.  Building upon the successful and award winning A14, the new A14MKII upgrades include a new Texas Instruments Digital to Analog Converter (DAC) supporting 32bit, 384kHz audio complimented 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 popular source inputs including aptXTM 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 has been engineered from Rotel’s award winning RA-1572 integrated amplifier with critical circuits and component upgrades including a Texas Instruments 32bit, 384kHz DAC supporting PC-USB 32bit/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 aptXTM 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 32bit 384kHz 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.  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.
