Bad luck W/ Musical Fidelity DAC


I purchased the new A3 24 DAC last week. For the first few days it was working great, yesterday the volumn level took a nose dive and the sound was fading in and out. I replaced all the cables and the power cord, but no change. When I remove the right rca plug, the left speaker played normal, and when I remove the left rca plug, the right speaker played normal. What is wrong w/ this unit? To MF's credit, there are going to replace it but my wait will be at least 3 weeks.

I ALSO BOUGHT ONE OF THESE AND SO FAR SO GOOD. I'M THRILLED WITH THE SOUND AND NO QUALITY PROBLEMS YET.
Musical Fidelity...I got all hyped after reading MF's review on their CD player, then remembered MF still believes turntables are cutting edge technology.
Did you not read the review in Stereophile where the unit was hand delivered by the owner of the company for review and while they were listening to it the thing stopped working and had to be sent back to England to be able to complete the review?
