Free Delivery. Cool beauty delivering 28 watts per channel of pure listening pleasure. Another new edition to the range for 2010, the Wi-Tube is compact & sexy, but still packs a solid punch. Producing 28W per channel this is no lightweight when it comes to power. Utilising a radical new hybrid valve design, the basis of which was first suggested in a theoretical paper 50 years ago, it just sings with quality... & looks stunning. Coupled with the Fat Dock for wireless connectivity. One may also use a wired connection on the RCA pair on the back of the dock direct into the amplifier if preferred.
