The HD700s are not the easiest thing to drive. would suggest something with at least 30-50 watts per channel into 8 ohms. with the impedence of the sennheisers you may be able to get a few watts output.
would also suggest you take the plunge and buy the least expensive denafrips DAC. it will blow away the chip set in your Marantz.
Happy listening.
