Dedicated line vs. power conditioner

Sean; yes, for awhile the only elements I was comparing were the dedicated AC/ground system versus the Tice Elite 4. I will note that before the dedicated system, the Tice power conditioner did improve music quality when used with front end components and pre-amp, but it sucked the life out of my big McCormack DNA2DX amp. Craig.

Here’s an inexpensive way to hear which gives you the most for your money. Trace the circuit, which provides the source of power to your equipment. Un-plug all other devices on circuit. This will take you very close to having a dedicated line. Then audition a power conditioner. A good dealer will be happy to loan you one.

Simply unloading the multi-tapped house circuit will absolutely not come even close to comparing with the superior performance of a properly engineered dedicated line. There are normally multiple connections & wire splices along the way through the house to that 'outlet of interest'.
However you can compare by running a "temporary dedicated line" strung across the floorboards etc. to your rig, but be prepared to follow up with a permanent installation because once you hear it, you won't put up with house wiring ever again.

Have to agree with Bob b above. An easy simulation is to use a quality 12 gage extension cord plugged into your laundry outlet (with laundry appliances unplugged of course) and run to your rig. Not quite ideal with the extra recepticle and plug, but a good simulation of what a dedicated line can do.

Alex has a great idea. Per The 1999 National Electrical Code, 210-11, C -2.

Laundry Branch Circuits: In addition to the number of branch circuits required by other parts of this section, at least one additional 20-ampere branch circuit shall be provided to supply the laundry receptacle outlet(s) required by Section 210-52(f). This circuit shall have no other outlets.
