Unison Research Unico CDE CD Players

I've enjoyed this machine but it has failed to work on 3 occasions. Today I had to attempt it 4 times to get it to work - shutting it down and re-starting 4 times before a CD would play. This is the third such event in as many months. I'm not happy,...

I have owned the Unison Research CDE for over a year, It has the optional DAC. I initially had to send it back as it had hum coming from the transformer when using the optional DAC. It was repaired under warranty.
