In Reply to: Which Universal Player would you upgrade? posted by John C. - Aussie on April 5, 2007 at 19:26:49:
....and if you don't care about video get SA-60. It is still "universal" player less video out.Regards,

It is a full blown audio-video system. I demand fine quality audio whether it be on CD, SACD, DVD or TV broadcasts, But having so many players in the system seems an unecessary complication now the universal players have matured.John

99.9% of the time, connecting a video monitor to a high-quality audio system will degrade the quality of both the audio and the video.The reason is that all modern video display use switching power supplies. All video connections are single-ended. There is a leakage current from the switching power supply that will get on the chassis of the video display. Connecting the video display to (say) a DVD player (that is connected to your preamp) means that all the noise from the video display is now directly coupled into your audio system.
There are a few ways around it, but they are either expensive, tedious, or both. Search the archives for posts by me with search terms like "video" AND "ground" and you will get more info.
Hey Charles,Hypothetically if the video connection was balanced (did I say hypothetically) would there be the problem you are describing.
Asked another way, is it the type of connection or simply the act of connection that causes the problem?
Thanks for your response. First viewing I did not read it carefully enough and see you were referring to the video monitor causing problems, not the player.In the system here, if I am listening to CDs etc then the projector (a Barco 808s) is turned off. And, like the superb Ayre units you make, the video circuits in most of the better universal players are also turned off for audio only use.
Now what happens to the audio when all that video is ON could be another story. Fortunately the sense of sight as well as sound is involved so maybe listening is less critical.
I would be interested to know what are the ways around it if the audio is in a completely different path (apart from the Universal player) to the video. At the moment I'm only connected to the projector by analog RGB (a 12 meter length of cable) not digital although that could be on the horizon in a few years time when the Barco dies.

The Barco is not really off when it is "off". It is actually in "standby". (That is why you are able to turn it on again with the remote control.) To turn the Barco all the way off, you will need to plug it into a switched outlet strip.If all you have is a DVD player, and no other video sources (VCR, satellite or cable box, etc.), then this procedure will work fine for playing music. But to have a better picture and sound when watching movies, then you will also need a DVD player that provides total isolation between the audio and video grounds. The only ones that I know of are made by Ayre (my company).
Unfortunately, our "universal" player does not have video capabilities. Our video-capable players are only compatible with DVD-V and CD, not SACD or DVD-A. So it becomes a matter of picking your poison. (Or else spending a bunch of money to get one of each, which is its own kind of poison.)
Keep the Barco for a while. It will be a while before there are any digital displays that will give you that good of a picture.
Yes, I will continue with the Barco for awhile yet. It has done over 11,000 hours but is still going strong with no discernable drop in outpuit from the blue or green guns. Having it on the floor rather than hanging obscenely from the ceiling has no doubt helped with that + the holes in the floor for the cabling give a flow of cooler air up to the unit.BTW, the video from DVD players is not connected directly to the Barco. At the moment it is via a component switching box -> DVDO HD+ scaler and that switching box & DVDO are definitely powered completely off unless we are watching video. Any new universal player will be connected the same way.
However there could be video nasty feedback to the Meridian 861 from the hard drive recorders which are on standby and have their digital audio outputs connected to the processor. But the Meridian is not handling the main L/R stereo signal which goes direct from the player to the preamp & amps etc. The only feedback could be via the second output from the McIntosh C200 which feeds into the Meridian 861 for surround sound or from the surround connections between the SACD player & the Meridian 861. Complicated - yup it is crazy, like me :-).
It is like this when listening to CDs or SACDs:
video recorders on standby (digital out) -> Meridian 861 -> centre, sub, side & rear speaker amps & speakers
SACD/CD player -> L/R to McIntosh C200 preamp -> amps & speakers
+ second output from preamp -> Meridian 861 -> centre, sub & surround amps & speakersJohn

I have also a satellite box connected to the system, and, unfortunately connected to the dish too, the solution to isolate it from the audio was an optical digital cable to the processor, and physicaly disconnect the HDMI cable from the TV, meaning, when watching cable the HDMI from the player is disconnected, when watching DVDs, the HDMI from the box is disconnected, never an earth loop with the box...A bit unconfortable, but it was the only solution, there are no filters for HD satellite high bandwidth...
