I have a AC Regenerator. Get dedicated line too?

While this might be true with pure power, it is not true for other regenerators IMO. I have tried the Monarchy Audio AC regenerator which only supports equipment up to 100 watts, so only source and preamps can be used. It is a terrific product for the price $700, did a fantastic job when connected to my CDP (Audio Aero Prestige). But changing power cord from the wall to the regenerator also had a lot of impact on the sound. It doesnt have a battery bank to store the power, so it is like a continuous regeneration happening. Why the power cord before the regenerator matters in this case could be (it is just my inference) because the regenerator itself is nothing but an amplifier with its own power supplies and circuitry. This circuitry also benefits from a better power cord so the power cord before it makes a difference. Pure power is kick ass product, no doubt about it.

Pani- Yes, the PurePower is different. The stored power available on demand in the massive batteries is probably the reason the dedicated lines, the Maestro outlet and the expensive power cord from the wall to the 1050 did not show any audible difference. IMO of course.

What I really like is that this regenerator allows high power amps to not only be connected to the unit along with source components, they actually end up performing so much better! I went back to the research I had done before my purchase and I remember this excerpt from their website helping me make my decision:

"The PurePower AC regeneration design provides something you might not expect from a power solution. Many power filtering and conditioning products are routinely accused of limiting the current flowing though them, thus starving the power amps with their need for lots of instantaneous current on demand. Testing shows how the PurePower actually has the capability to deliver more current that even a completely unfettered and unfiltered household outlet. In the Bryston equipment test measurements shown above, the 9B SST demanded AC to produce the required output to the speakers. The Amp drew 3.88 amps at its peak demand. When powered from the PurePower 1050, the amp was able to draw 5.6 amps at peak! That's almost a 50% increase! This is possible due to the nature of our AC regeneration technology. One of our primary goals is to be able to provide for maximum current variation on demand without allowing the sine wave or voltage level to be adversely affected. While you want voltage to be rock solid, noise to be at a minimum and the sine wave to be pristine, you also want to be able to have the most current possible available exactly when it is needed. The more instant current change you can provide without affecting any of the other power variables, the better your system can perform. "

I have a Purepower 1050 and I'm still trying to determine if the power cord feeding it makes a difference or not. I know it shouldn't.

Foster 9, Try inviting a friend over, putting on a very familiar track at an involving level, closing your eyes and having him/her quietly unplug the power cord from the wall and back in again a few times without telling you when and determine if you can hear any difference between the expensive PC cord and no cord at all.

If you hear a difference of any sort, it means that something from the 1050 on back (pc cable, dedicated line, outlet) is able to affect your system. If you weren't able to tell when your assistant unplugged or plugged back in, the 1050 is doing it's job. Have fun!

Let me tell you people a disturbing news. I heard that newest Purepower units are even better. So what are you going to do now?
