Today I would like to talk about the backbone of my system – the rack, this sacred place where all the electronic components are placed. Some of you might ask what is the difference between a regular lowboard one can obtain in every furniture shop and a HiFi rack made especially for audio applications. In order to comprehend the difference one should first realise what a tremendous impact vibrations have on audio reproduction.
I don’t mean to brag guys, don’t take me wrong, but the system really rocks these days and this is something I would like to report. I suspect the main reason for the outstanding performance lays nowhere else but in the improved room acoustic. As one can see on the images, there are several diffusers scattered around, also one sail is attached to the ceiling. Let me introduce you briefly to what I did recently in terms of room acoustic treatment.
Following the buzz around the Belden 8402 microphone cable used as interconnect that swirled around Jeff’s place I decided to build one myself. I decided also not to follow the classical convention of connecting conductors and shielding to RCA plugs suggested by Mr. Shirokazu Yazaki nor the contemporary norm of connecting the shielding only on one end to the ground, but to follow the methodology suggested by the french forumer and Jeff’s frequent visitor Dominique.
The importance of symmetry in terms of equal distance of the loudspeakers from the side walls derives from the fact that what one hear is not just the direct sound of the speakers but also the reflections from the room walls. Especially important are the first wave reflections for they contribute to the spatial quality of the stereo image and its tonal richness.
Over the weekend I decided to swap the places of my audio system and listening sofa just to check out how it will affect the sound. I was concerned with the lack of enough space between the speakers, but It was just impossible to further increase the distance between speakers without entering the door boundaries. The task was to keep the room functions intact so that the door is passable.
