Ok to use a Shunyata Hydra A-4 with a VAC 70/70?

I have a VAC Renaissance 70/70 amp and VAC Renaissance MK II preamp. I have been advised to get a power conditioner since the lights in my house dim every time the A/C and furnace go on, and I am considering getting a Shuntata Hydra A-4. Any problem plugging the VACs into the Hydra?
Assuming there is nothing wrong with your electric, as Rhljazz suggests, I would get something for the preamp but probably not for the amp. Although, if you get the Hydra, you can try it both ways. I have a 30/30 and it goes directly into the wall. Also, since we are talking about power sags, a regenerator may be a better choice. If you call Cable Co., they have all of these products to lend out so you can try them in your system first, before you buy. I use them all the time for stuff like this.
The PS audio Power plant 10 is a remarkable and realistic resolution to solving problems between your system components and the electricity coming out of your wall. I was skeptical, but needed to protect my system against spurious and dubious power in a new, somewhat rural location. I did not want to lose the great sound I got by avoiding any filtering with power conditioners, plugging directly into the wall with dedicated lines. I decided to go wih the Power Plant 10 and, even though I could have gotten a better price, I opted for a demo from the manufacturer with a 30 day trial period and full warranty.
The results were impressive and the sound delicious and unbound, BUT protected. Exactly the effect I needed, and even a bump up from the previous unprotected, but dedicated lines. I did install dedicated lines and now the Power Plant 10 is an important component to my system. I mention this because my power amp is the VAC renaissance 70/70.The rest of the system is equally as demanding and has responded well to the addition of the PS 10.The demo and "refurbished "units run 3,500.00$ new they are 5,000$ and the going used price is 3,000$.Last thing I wanted to do was spend a bunch of money on a "power conditioner" type of product, turns out it should have been the FIRST thing I bought. As always, do your research....this might be your magic bullet,

Jazz courier: do you have all of your components plugged into the PP 10? Did you contact VAC about whether they had any recommendations about using an AC regenerator? If so, what did they say?
