Clean Power without the drawbacks of Conditioning Filtering. Advice?

Yes, the PS Audio "Noise Harvester" works well for removing noise from the line as Elizabeth mentioned. If anyone is interested in more information PM me.

You might look at the PS Audio P-20 regenerator.  Plenty of power out of it, and seems to be a lot of happy users so far.  I use a pair of P-10's happily now, and will likely switch to the P-20 this winter.  They allow 30 day trials.

I thought the OP didn’t want any filtering or regeneration.
  Although, the High Fidelity MC-6, Magnetic Conduction Power Distribution Block looks interesting for $999. 
No filters or capacitors.

Dirt cheap.. Plain old small quartz crystals, add a bit of automotive dielectric grease to insulate individual crystals, place in small baggies...(I do 1/4 inch thick, about 2 inch by 1.5 inch packets.)I put some in the AC duplex area and in and on the AC Plugs.Seems to work well as I just bought some PS Audio Noise Harvesters, and they register zero noise on that line. It may be luck and it may be my notions have some merit? I wrote a new thread about the noise harvesters,

I did something similar to what Elizabeth has done , 
I took a Hubble HG outlet strip took out the circuit breaker and rewired 
everything internally and externally with 10 gauge wire from Cardas 
and use a hospital grade plug .
