Excellent sound reproduction across the frequencies. The inbuilt internet radio facility brings crystal clear radio reception where the DAB may be lacking in signal strength. CD player works fine. The overall build and quality is very good. I haven't got to grips with all the features as yet. Instruction manual is very basic but i'm told there is much more info. available online! I have sampled the Bose equivalent. They are both very good. If you want really deep base that hits you in the stomach, then go for the Bose. However for an all round rich, smooth sound with clarity and sharp definition then the Como is the one. There is a graphic equalizer which allows for base and treble to be set individually to suit one's particular taste. There are 8 presets available from the remote control or from buttons on the unit itself. My only gripe is that I cannot have 8 DAB and 8 internet radio presets. Rather it appears the 8 presets cover all the radio sources. I strongly recommend a demo before buying. The Como website lists local stockists. I went to Stratford upon Avon. Whilst there, I was able to compare with the Ruark equivalent and others. The shop in question was very helpful and knowledgeable.
