yes.

http://www.gracedesign.com/The m902 also cleverly adds stereo unbalanced analog line outputs for connection to studio monitors or any speaker system, allowing it to double as an elegantly simple high fidelity monitor controller or even a purist audiophile preamplifier / DAC.
for inputs, the 902 has balanced analog XLR, unbalanced analog RCA, S/PDIF coax, S/PDIF optical, AES (via XLR), and usb (not usb 2.0, and limited to 16 bit, 44.1 and 48 kHz).
outputs include two 1/4" headphone jacks on the front, and unbalanced RCA outputs on the back. Grace is also now offering an upgrade (for $195) to replace the unbalanced RCA outputs with balanced analog outs (via two 1/4" TRS jacks). So if your power amp has balanced inputs, you could get that upgrade from Grace and run balanced connections the whole way.
