There are many more threads if you need more opinions.
Don't forget about speaker systems that are wirelessly connected for broadcasting around the house. It is nice (when my wife is not at home) to flood every room with the dulcet tones originating from a Flex. Speakers that are Apple Airplay compatible or the Sonus systems makes this possible.
Many thanks everyone for the recommendations. I have now made a purchase of the Bose Companion 2 series 3 speakers. What I like about these is that a utube review did state that they are not just all about base, so many cheap computer speakers push the bass through the floor, OK for modern dance but not good for the 6Khz wide audio bandwidth of the radio! They also look stylish, thanks again all and 73's de M0NAG
I decided to use use JBL Control 1 Pro monitor speakers after an audition and reading various reviews. These are fairly inexpensive studio monitors, but do require separate amplification. I intended to use a modest hifi audio amplifier to achieve this and indeed route the audio from multiple radios. However while I was looking for a suitable amp, I stumbled across the Yamaha Network CD Receiver CRX-N560D...this not only routes the audio and amplifies for great sound out of the JBL monitors, but also adds Analogue / DAB broadcast radio to my shack and fantastic Net based radio stations too...plus a CD player and the usual USB audio connections for ipod etc!
I love this little receiver, it compliments my shack very well, bringing the best out of my 6500 received audio, whilst also adding more radio to the shack! (and some great music for when i'm working on the bench!)...Picture attached with the white version of the JBL monitors shown (also available in Black) and the Yamaha receiver shown to the left of the Palstar AT2K.
