Post Subject: Digital Equalisation and sound qualityPosted by custodian on: 4/24/2015

My system lives in a small room with poor acoustics. Fact of life until I get round to building the planned perfect music room which has been in design for 5 years and still is just a concept!
Bass end is lumpy so I decided to try various solutions to smooth out the room response. As part of that exercise, I bought digital equalisation equip me t from Z Systems (RDP-1 preamp) and Tact. Any benefit from equalisation was far outweighte in both cases by a loss of soundstage in the image. A reduction to a 2 dimensional picture which I assume is due to introducing another stage of electronic processing.
Best practical solution was to start with a 1hz interval tone and find any localised resonance peaks which I then tried to dampen (doors, mirrors, windows, ornaments etc). Broader peaks were ameliorated with damping panels on the walls and in the corners, all of which had none of the downsides of adding additional electronics to the signal path.
