I am sure you know about this product - excellent ALL IN ONE streaming amplifier - sounds amazing and with BluOS works with almost every streaming service.  A bargain at this price!

Also includes the full frequency version of Dirac Live and the calibration microphone. I am sure this will make a big difference to the sound of your loudspeakers in your room. I and almost every reviewer have noticed significant improvements using Dirac.

I can demonstrate in Swaffham.  Can also arrange collection in Cambridge or East London (subject to my schedule)
