Anyone who has a Marantz SR4400, SR5400, SR6400, SR7400 and SR8400 and are experiencing Audio Drop-outs (the audio disappears for less than a second and then comes back), this is a problem with the new Cirrus DSP chip in the units. Marantz is aware of the problem and are offering a fix for it under warranty. This problem is also related to an overheating problem with the amplifiers. I have a Marantz SR5400 and will be doing a review on it in this section for those who might be interested. Need to spend some quality time with it first.
