My current rig is a 6-space rack consisting of a QSC RMX850 power amp, Ampeg SVP Pro pre amp, a Korg DTR-1000 tuner, and a Furman power conditioner. The 6th space is currently empty. It is very bulky having a 6-space rack, so I want to move to a 4-space unit but keep my current components. I've heard of power conditioners that also have tuners on them. Can anyone recommend a good one to consider? BTW, I'm upgrading my QSC RMX850 to the PLX series, so if anyone is interested in a practically new RMX850 power amp, let me know.
