Have to say I'm a bit disappointed to read all these posts....

I've been installing these units in every multiroom system in a year. Haven't had any problems that come to mind....

Hope I'm not in for a rude awakening...

We switched to Denon because we had 90% failure of Harman Kardon FL series CD players...

Don't laugh, but I wish we could still buy Technics SLPD units. They were awesome. Mine is still going after aprox 12 years.
