The High End Swiss 2011 audio show was held from 21st - 23rd of October in Regensdorf, Switzerland. According to the show organizers approx. 2,500 people visited the show. Avantgarde Acoustic had its own big showroom presenting the Trio with 2 x Basshorns, driven by the new XA power amplifier. As in the last year we were more than happy with the sound and the response.
