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.  The D-5.1s produced a wonderful, truly 3D soundstage, with lifesize images of every instrument and vocalist, stable, precisely placed and each occupying its own space.  The system delivered the scale of orchestras and large ensembles effortlessly.  The fullrange sound was completely grainless and seamless throughout the audio spectrum and produced with the grace of a true flagship system.

The D-4.1 was almost identical in sound, only yielding a little in its ability to produce the full sense of scale of power music in the large room.

Remarkably, the Scansonic MB-2.5 displayed very much the same sonic character, albeit with slightly less resolution and scale.
