German magazine, "Digital Home" have had a chance to review Tangent Ampster BT.
Under the heading: "Amplifier with fun factor" the magazine finds the Tangent Ampster BT to be extraordinary value for money:
"For only 200 euros you get a device that makes you light up in an instant smile."
With the usual German thoroughness they also measure specs like output per channel and find that the class D amplifier more than lives up to the announced 2 x 50 watts.
