Rotel announced acoustic and performance upgrades to three of their 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. 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 new A14MKII upgrades include a new Texas Instruments DAC supporting 32-bit/384kHz audio complimented by 25 component changes in its 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/384kHz, MQA decoding and rendering, analog, digital and a Moving Magnet Phono Stage. The A14MKII is also certified as Roon Tested.
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 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 the power supply render audio with a wider, deeper soundstage and improved accuracy and positioning, the company says. The MM phono stage, XLR Balanced, Coax, Optical, RCA, front iPod USB and aptX and AAC Wireless Streaming Bluetooth connectivity ensure support of all popular sources. The RA-1572MKII’s PC-USB connection is certified Roon Tested.
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/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.
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- it/384kHz, Moving Magnet Phono Stage, Analog, Digital, XLR Balanced and front panel USB for iOS devices. It is, also, certified as Roon Tested product.
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.
