I noticed last night my 5400ES has a spinning noise. A mechanical sound at the player, not something sent out the analog path.
Haven't had it long. Sometimes you hear it, sometimes you don't. Maybe its picky about CDRs, though I'm using the same brand of archival quality media throughout. Forget the name, its a Japanese derivative of JVC or something.
And this is not the sound you hear when starting from a stop, but an ongoing sound that only stops when you stop spinning.
I've had the player for a long while now, probably since 2008. Feels like a million years ago now.
I may just buy the OPPO to use as a transport to whatever source upgrade I end up getting.
