Versatile Unit With Built-In Preamp

Meant to live at the center of your high-end audio system, the Matrix Quattro II features the highly regarded ES9018S DAC, an XMOS interface, and a LME49600 ultra-low-distortion headphone amp. It comes loaded with a variety of inputs and outputs; the inputs alone include two coaxial, two optical, a USB, and an AES/EBU—an unusually high number, and ideal for switching between many sources. The Quattro II can send signal out either by XLR or RCA. It has a built-in preamp (the output can be boosted by 10 dB) and comes with a remote for convenient control from across the room.

The Reviews Are In

Head-Fi user ostewart says, “Overall, I do like this DAC. It is very handy having a device that I can play all my sources through, along with the USB being very quiet (my one big gripe with the DDS DAC-01). It plays well with my stereo setup, along with being able to plug it into my Feliks Audio Espressivo for headphone listening. The dual headphone output is also handy if using with friends … The remote is lovely, and the volume control is very easy and intuitive to use. A well-made, good-looking, and future-proof product. Very nicely done, Matrix Audio.”
