I am assuming that it is not "a good thing" to do so, although it would cut down the speaker cable run by a few yards. Are there any mats or wall brackets that could be placed close to the surface of the G Plan sideboard which would be acceptable? I take it that the Cyrus amp equipment can be placed direct onto the sideboard as there would be no moving parts, I am also thinking about a Cyrus wall unit for the amps and CD which looks rather neat but that would still leave the TT.
