I want to place my valve monoblocks near (behind) my esl speakers. I know that valves are susepable to vibrations (microphonic) and the electrostats kick out just as much sound behind as in front so is it a recepy for disaster? Could I house them in something (open top of course) to absorb defract the vibrations or should I keep them as far away as possible? Amps are Quad II40's KT88's and speakers are esl988's Its worth mentioning this is an asthetic placement not for sonic gains said to be had from long ic's short speaker cables. Thanks
