Is clean power kind of like , how proper room treatment is often over looked until the fine tuning of "how can I get my bass to sound better"? Most of us invest in all the creative stuff first ( DAW, software, pre-amps, converters, mics etc) and over look the few key secret's that, IMHO truly separate the confused. You need to hear the "space" to actually harness, mix and master sound and produce rich music. This is one of those overlooked topics only the few take serious and I believe, can hear a difference. I believe your gear has to be at a point though, where it is transparent in the first place. I look at power like a Fuel Dragster looks at the time it takes to bee line from point A/B and win over and over. I am building my dream hybrid DAW, (the audio dragster) and am wondering: What do you use for power conditioning? How does power conditioning effect your mastering?
