In our household we play IP Music Switzerland daily as 'background' music throughout the day in our kitchen, and would thoroughly disagree with your assessment as regards the "quality" of this station.
Sound is totally subjective, and certainly comes down to both the listener's personal taste, and just as importantly the actual 'equipment' on which it is played.
You will often read criticisms from people here in the forums with regards to the bass response of the SoundBridge Radio, some say it's too little, whilst others say it's too much - I would suggest to you that it's nothing but an issue of personal taste.
. . . . And on a final note, with over 5,500 live stations, Radio Roku offers you plenty of scope to choose your very own 'personal' favourites.
