This player continues to thrill me.
I've been meaning for quite some time to get away from my multi-channel Atmos thingy receiver. The only thing that has kept it in place has been the use of the remote for input switching, control of my Marantz Blu-ray player, system volume control, and lastly the ability to break the sound out of the HDMI and send it to my stereo amp. With the retirement of the Marantz player the list of reasons to hold on to the AV receiver just became shorter. I'd just lacked the spare moments to attempt any experimentation.
I finally tripped over an adequate block of time that was just sitting there, derelict, which provided the opportunity for me to play some bypass shenanigans with the receiver. I took the HDMI output from the Oppo and sent that directly to my panel display, and the analog outputs went to my highly-regarded Nakamichi CA-7 preamplifier. With everything connected thusly, I found that I had stellar sound coming through my speakers, but somehow the tv was still getting sound and passing it through my Sonos "home theater". I silenced that noise, then found that the soundtrack was playing perfectly through the analog stereo but the vocals were far, far back, as if the speaking roles were phoning in their post-production dubs and Foley from the comfort of the loo. More research and experimentation were warranted.
A few layers into the Oppo audio menus I discovered a positively wonderful setting that allowed me to choose what audio output format I wanted. It was but a moment to select 2.0, no LFE, and my show was ready for the big room. I found that Oppo thoughtfully provided a volume control on the remote. With the telly managing the inputs, the analog sound playing perfectly through the stereo, and the Oppo controlling the volume for my ancient, non-remote but very rare and stellar preamp, the Marantz receiver has been retired. Its a brilliant unit but not my particular malt anymore. I do believe my adventures with multichannel are over.
