RE: I'd try a different SACD player
Posted by airheadair on March 15, 2020 at 20:11:14:
Thanks to everyone who had suggestions about my SACD problem. I remain mystified, after some further investigation.
1. A new copy of the SACD exhibits the same problem. I think this rules out dirt or other contamination.
2. No other SACD that I have tested seems to have the problem.
3. I moved my OPPO 203 from the HT room to the main music system and tried the SACD there.
Same problem. I think this rules out the Marantz.
Perhaps I was wrong that on Sunday the disc was fine. The noise is not noticeable at low levels, but becomes very noticeable as soon as I turn up the volume to realistic levels (which I don't usually do).
My conjecture is that some HF junk on the disc overloads the OTL amps beyond a certain level.
This is consistent with what Ralph has said. I wonder if a ferrite bead inserted in the interconnects would help. However, if the problem remains confined to this disc, (which I dearly love), I probably will not take such a measure, except perhaps as an experiment.
