Raidho Acoustics demonstrated their D-5.1 and D4.1 loudspeakers and the MB-2.5 from sister company Scansonic HD.  Amplification for the demonstrations was provided by the Aavik Acoustics C-300 preamplifier and a pair of M-300 mono power amplifiers.  Cabling, grounding and power conditioning for the system came from Ansuz Acoustics.

In its various configurations this is the system that I most enjoyed.
