After quite a bit of trial and error, I have landed on what I feel is the best setup for pure analog stereo playback. I initially purchased a miniDSP with the intent to run the front M&K 150's full range and then use the miniDSP as a low pass crossover. The M&K's S-150's are in no way full range speakers so this limited the volume quite a bit.
Here are two things I've landed on after reading further on Oppo's website and speaking with Oppo tech support.
Option 1: The 205 has an enhanced HDMI feed for audio that results in extremely low jitter. I fed the audio only HDMI from the 205 into the MRX and set it for stereo with a second room correction profile with lower cutoff frequency. I use the Oppo iPhone app to select high res files from my Western Digital 2 Tb hard drive connected to the 205 via Audioquest USB cable. I don't want video potentially messing with the pure sound. The sound is AMAZING! Details on the audio HDMI here: https://www.oppodigital.com/KnowledgeBase.aspx?KBID=129&ProdID=UDP-205
Option 2: I tossed the MiniDSP after talking with Oppo tech support. I use the 205 main analog R/L out and the subwoofer out on the 205. Since I still want active sub outs from the MRX, I feed this into a combiner from Edcor for my right sub only. So the signal path is 205 subwoofer out to RCA bypass switch, then to Edcor combiner. The sub out from the MRX also goes into the combiner and then the single output to the right sub. I only active the Oppo sub switch once I have switched the MRX into analog mode. This input is set for no processing and no room correction so the MRX subwoofer out is disabled on the MRX and as long as I am careful, I will never have two sub signals going through the combiner. Oppo stated once set up, the subwoofer out is active even when running HDMI to the MRX. The 205 is then set up as a 2.1 system with the subwoofer activated. I set the crossover same in the Oppo at the same value the MRX picked and adjusted the sub volume on the Oppo. The 205 does the bass crossover and still processes the music using the 205's high end DACs. The sound is AMAZING.
To be honest, option 2 is just a hair more transparent than option 1. I expected more out of the better 205 DAC's, but the Anthem DACs are decent in their own right. I like options, but now having an A/B comparison, I would have just done option 1 and called it a day. I am still trying to determine if the sound is good enough for me to get rid of my 2-channel system in my office. I am running Watt Puppy 6's with a Music Reference RM-200 Mk II, Benchmark DAC-1, and Transparent cables. Comparing an $8000 tube amp to the Anthem really isn't fair, but I have to admit the law of diminishing returns is at work here. The MRX-720, Oppo 205, M&K combo comes pretty darn close. The warmth and magic a deep into the music "space" is missing, but it is not as far off as one would expect.
Hope this helps anyone else wanting to take advantage of the 205's excellent analog capabilities.
