Rotel A14MKII Bluetooth stereo amplifier and Texas Instrument Dac 384 kHz / 32 bit

The Japanese manufacturer announces the renewal of three of its prestigious stereo amplifiers, the Rotel A14MKII, Rotel RA-1572MKII and Rotel RA-1592MKII. On the program, new features of course, but above all, new components directly from the Michi premium series. We start our presentation with the A14MKII model, before coming back through subsequent news on the other two.

Regarding the major evolutions offered by the Rotel A14MKII, the Roon Tested label (the Roon application therefore supports the product and adapts the quality of the audio stream read to the capabilities of the device). Finally, we also note the MQA compatibility and the integration of a Texas Instrument 384 kHz / 32-bit digital-to-analog converter instead of an AKM specimen, the manufacturer of Dac still not having resumed its deliveries since fire at its factory last year. It was therefore the choice of this Dac that prompted Rotel to adapt the audio architecture of the A14MKI directly from that of the Michi specimens.

Main specifications

For the rest, we find a Class A / B amplification associated with a beefy toroidal transformer delivering a total power of 2 x 80 W RMS into 8 ohms and four slit-foil capacitors of 100000 microfarads each, capable of handling the most demanding speakers.

Asynchronous USB port in the menu

At the inputs, there are five RCA stereo inputs (Phono, Tuner, CD, Aux1 and Aux2), two optical, two coaxial, one asynchronous USB port (installation of '' a driver necessary for managing DSD files), two powered USB type A ports (one on the front), a stereo Pre-Out output for connecting an external amplifier or to connect a subwoofer, an RS-232 socket , a 6.35 mm headphone jack on the front and four pairs of isolated screw terminal blocks to supply two pairs of loudspeakers (A / B).

Possibility of control via IP

Last details, the Rotel A14MKII is also equipped with an Ethernet port for control via IP and APT-X Bluetooth compatibility to access dematerialized content stored on a suitable peripheral (smartphone, tablet, game console, computer…).

Availability announced for the month of July, in black or silver. Indicative price: 1,399 euros.
