Rotel has released acoustic and performance upgrades to three of its 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 level circuit locations which leverage the design elements of 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 three years in the making.

The A14 is the flagship integrated amplifier model in Rotel’s 14 Series. The new A14MKII upgrades include a new Texas Instruments Digital to Analog Converter (DAC) supporting 32-bit/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 changes in the signal path circuits provide a richer and fuller audio performance with even more lifelike reproduction of the music.

The A14MKII supports all popular source inputs including aptXTM and AAC Bluetooth for wireless streaming, PC-USB up to 32-bit/384kHz, MQA decoding and rendering, analogue, digital and a Moving Magnet Phono Stage. The A14MKII is also certified as Roon Tested delivering the best possible experience using Roon software.

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.
