IMO, the most bang for my buck by far has been adding dedicated lines, 1 for amps, 1 for digital, 1 for phono, 1 for my preamp, using Hubbell 8600 outlets and 10ga wire, the whole job cost me $310. Prior to this I have used Chang, Power Wedge, Seakay, Counterpoint conditioneers...which all had subtle improvements...my advise is to first get dedicated lines...then add on Line conditioners. BTW, make sure to run a dedicated ground.
