RE: AC Power

** What is the technical basis for power conditioning, AC purifiers, etc.? **

Power factor correction, voltage spikes, surges, RFI and EMI. Ironically many of the garden variety products specify their capability in these areas. But as you may have guessed, many audiophile vendors leave their spec's up to the users' imagination.

Compare Furman spec (mainstream )

to Shuntaya's (audiophile)

** I have also read quite a few posts stating that a high quality power supply should isolate a component from AC issues. **

Some probably do, but as with many other audiophile products with zero (or near zero) specs, there is little guidance. Stuff like power factor correction, and surge suppression are fairly standard stuff that should be specified. I will rather go with mainstream mfr on stuff like this, an ineffective product could prove very costly in the event of real AC issue.
