Suggestions for a conditioner/surge protector?

If you can't do dedicated lines, then get a power regenerator (not a conditioner/filter -- they ruin sonics and represent "old technology" IMO) Consider an Exactpower EP-15A (my favorite ;--)

If you COULD do dedicated circuits and your power company provided relatively stable power, you wouldn't need a power "conditioner" either -- maybe just an isolation transformer.

Power conditioners IMO are high profit items whose charms have long ago faded, and any "surge" protection they offer is false security. If thunderstorms are iminent, UNPLUG YOUR SYSTEM!!

Vman, I can't debate your results. However, technically speaking, all a conditioner can do is filter out certain kinds of noise. It can also smooth out voltage spikes or, if they're too big, try and clamp them before they destroy your equipment (ha ha!)

They can't fix truncated sine waves, hold up sagging voltage, or lock the AC at 60 Hz, only regenerators can do that. And conditioners do what they do at the expense of fastest energy transfer from wall to equipment. Since energy transfer is more important to amp performance than noise filtration, that's why most folks with ded. cts. just plug their amps into the wall using big 10 AWG power cords.

I'll say this: if you believe a power conditioner made that big a difference, then you owe it to yourself to try a balanced power unit on the front end stuff, instead of a conditioner -- that'll really blow you away!

Vman, honestly, I don't think you need an EP-15A (regenerator.) Just plug your amp(s) into the wall and get a balanced unit like a BPT, Equi=Tech, or Exactpower SP-15A for the front end stuff on the other circuit. That should do it.
