What HFL Thinks

Devialet 440 Pro - There really is nothing like the Devialet, every review, even from the most respected journalists who have heard it all can’t say enough good things about the whole range. It is certainly revolutionary with many patents against it including the hybrid power design at its heart, using both Class A to voice it and Class D to power it, all very clever. Not to forget the online Configurator, Ipad app, Streamer section, built in phono stage, high quality DAC that up samples all sources to 24/192, even vinyl + free firmware updates for life, oh yes and it looks quite nice too. Devialet could well be the ‘Future Of HiFi’ so why not pop in to HFL to see and hear it for yourself.
