Yeah -- really too bad.  I read that due to Netflix and streaming music, DVD's and CD's are really down in sales hence their potential decision to exit the market.

  Bang for the buck for sure however lots better out there. As an all in one player NONE better. Meaning movies and CD, SACD, transport.
  Oppo internal DAC VG however better out there.  Everything depends on budget, unfortunately.

Improving the sound through these resonators is quite the interesting idea. I wonder if the longer sound waves at the very low frequencies act as a carrier of sorts to aid in the travel or distribution of the other sound waves.

Ok, got the cheap version of the resonator, but no power supply and no info other than 12VDC @0.5 amp.  The coaxial plug for DC power polarity is not marked. 

From some looking at similar units it takes a 5.5mmx2.1mm (hard to tell or measure) coaxial DC plug with the center +12VDC.  Found a wall wart with a 12VDC@1.7A output from an old backup drive I already have.  Coaxial connector fits and powers up with a green LED.

Probably need 2 as the info states one unit covers about 160sq-ft.  Will see if one does anything.

 Hi Charles, I use an Oppo 103 for playing discs with digital out to my dac, playing digital files from a solid-state drive plugged into a USB port, and watching things like Netflix online.  Plus I run my DirecTV cable box through HDMI into the Oppo.  I don’t care much about the analog output because my dac is better. But I would like the video output to be better which could be the Oppo 203 I believe. Any other suggestions if the analog output is not important?

Nobody really knows why it works, literally. But you will still see all sorts of conflicting theories that people make sound like facts. The thing that is true is that at least some people do notice a positive difference in the sound. And what’s nice about Amazon prime is that if you don’t notice a difference then you can just return the thing.

However I would highly suggest getting at least a cheap 12 V battery to start for the power source because a crappy wall wart may mess things up so that you might actually get a negative effect. Pure power is the way to go, if you can do it.   And since it is a steady current pull you won’t need a BatCap.

 I also installed a switch on the power line so it is more easily turned on and off.

Thanks, Gary

   Gary we are using standalone linear 5A power supplies in lieu of wall wart. A big improvement. Do you think a battery is better and why ?
   Now have three in room. Two RR-888 and one RR-777. Adding the 777 was mind bending. Three for me . Besides the sonic benefits both my Wife and I are sleeping better after being in the treated room for hours.
  Installed RR-777 in bedroom after realizing the affect from listening room. Just so relaxed. Buy the cheap ones and get several. Just get some.

 I have a bit of mixed feelings about that. In general a battery should be better since there is absolutely no conversion in the battery from AC and no chance to get any noise in there. However, I have a Tortuga LDR light dependent resistor preamp which I love, and it runs off of 12 V DC. I hooked it up to my battery/batcap and I thought it would be amazing but it actually had some noise, a bit of hiss. Which really blew my mind, where in the heck is that noise coming from?  When I hooked it up to my laboratory quality five amp 12 VDC power supply all of a sudden it was silent. Weird… You might just go buy a cheap 12 V battery (or to 6 V batteries and put them in series) and try it out for yourself to see. It may be that that power supply is better. 

 I have found the best thing usually is to try one way and try another way and just compare them. Forget about what you think it should be or what somebody else told you it should be.  Unless they are telling you not to jump off of the top floor of a skyscraper. You might listen to that one.

Battery noise is common.  Sulfation and other types of chemical noise are not subtle with a high resolution, high sensitivity system. That is why I came up with the BatteryBUSS years ago.  The noise is easily suppressed, but it is a problem unless it is addressed.  I like batteries, but they are not a panacea.  The output impedance of a battery is relatively high and it needs to be reduced in order to get the impulse/transient response we all crave.  Steep rise times are essential.
