I have found M400 II to be clear, very strong and focused in the base and very good as a link between CD and Amp.

Some treble rounding which reduces harshness but can make you think its a bit too smooth.

M 400 ii is a good cable. It excels in base resolution and crispness.
It sometimes rounds off the treble a little too much and is not quite as well balanced as M 550 i but is clear with vocals,clean and is relaxed in sound.
It generally has to be said that it is in the top percentage of cables at this price point and I would recommend it for cheaper cd/amp connection set ups where sometimes treble brightness can be a real turn off.
It represents good value for money at this price point and as such has to be recommended.
It in common with other Monster cables is very quiet in operation-which is hard to explain if you havent experienced it.
All in all a good buy.
