Here is an excellent review featuring Monitor Audio's award-winning Silver 100 7G bookshelf speaker joined by Roksan's Attessa Streaming Amplifier. Ed Selley from Sound Advice offers his insight and praise for the combo.
"The mid bass driver has impressive low end weight to it which lends this duo a room filling authority that it retains even at comparatively low levels."
"...the Attessa should be seen as demonstration of how to build a modern hi-fi product... Thanks to the BluOS module, the Roksan is barely harder to set up than a wireless speaker. Controlled via a phone or tablet, the whole experience is slick, logical and entirely user friendly."
"Both of these items are strong performers on their own but in combination they’re hugely talented. When you combine this with the flexibility and user friendliness of the Attessa platform you have a seriously accomplished audio system."
