I don't like using AVR for music especially if its critical and you want "good " quality... I don't know what it is but there is something about an avr vs say an integrated amp or a stereo receiver that makes the avrs sound feel "played with" or "tampered"....
If I were spending $400 on what you are looking to do and wanted something that would supply worry free music listening I would go with...
Amazon.com: MUSE HIFI USB to S/PDIF Converter Decoder Mini USB DAC PCM2704 Black with USB Cable: Electronics
and depending on what you need for power either
a Topping TP60 which I love the sound of, its VERY detailed and has way more power than you would imagine, I know it says 100watts but I will put that against any 100X2 avrs amp section...
Amazon.com: Topping TP60 Tripath TA2022 50WPC (80WPC 4 Ohm) Mini Amplifier: Electronics
or
an APA150 for the price you won't find better, I own a few of these, if you need more power in your budget you can buy a pair of them and use them as mono blocks {which IMO is the best stereo sound, mono blocks insure 0 cross talk and give you balance control, although you need to adjust both volume knobs unless you upgrade to a dac with a volume control like the audio engine d1

I own every piece of equipment I listed above, the apa150s, both dacs, topping tp60, and 3 of the lepai 20202's---- you wont find better for the money.. In my garage I had a pair of CBM170 bookshelfs and an APA150 integrated amp with the muse dac and the sound is that of something most people would spend in the range of $1000 for...
Amazon.com: LP-2020A+ Lepai Tripath Class-T Hi-Fi Audio Mini Amplifier with Power Supply: Electronics for $20ish the power is more than you would expect, clean sound, and very reliable..
CBM-170 SE High Performance Bookshelf Loudspeaker on sale...
that stuff is going to be much more reliable than an avr.. and to answer your question the marantz would be what I buy between the two you listed, but I would rather see an integrated system with a very short signal path..
