I have been driving my Totem Arros with the older B-60 and 2B-LP combo in bi-amped mode for well over 7 years now and have no real desire to change the amplification. The accuracy and transparency of the Arros are well served by the 2 Brystons with the support of the Dreamcatcher powered sub. Extremely detailed, transparent, dynamic and yet natural and musical. Imaging and soundstaging with lots of depth adds to the illusion that you are at the venue of the performance. This is in a relatively small 12x20 room.
