For those who want the very best in sound and performance, here is the SS-101 Signature power amplifier from Vitus Audio (Denmark).  This 85kg beast puts a very conservative 50 wpc output in Class A, or 100 wpc output in Class AB.  Don't be fooled by its output power, it is capable of driving the most demanding speakers while exposing micro details / dynamics without compromising the coherence of the recording.  The combination of these Vitus audio amplifiers with Focal Grande Utopia EM is one of the best sounding systems at the 2011 Munich High End Show.
