Is anyone using a Monster AVS2000 with a RGPC 400? If so, do you see / hear any improvements?
Portonyl, I'm using the Monster AVS2000 with the Monster HTPS 7000. I find they do EXACTLY what Monster claims they're supposed to do. There're excellent...

Can anyone with first hand knowledge tell me what kind of mess i will experience when installing dedicated lines.
Thank you for all your help and advise

I had the electrician install an EP2050 "Waveform Correction Absorber". It mounts to the panel. You can read about it at:

www.ep2000.com

This product was designed to protect and purify power for huge, high tolerance computer aided manufacturing equipment and is now being offered for home use. Great company to work with and very interesting product that both protects and purifies without any of the downside effects (and cost) of power conditioners ETC.

Hope this helps.
OEM, it really depends on where your room is in comparison to your main electrical box. For me, I would have to open up the dry wall and snake cable through a lot of wall studs. Both a messy and costly proposition. This is why I am going the AC Regen route. If you are lucky, it may be straight shot. If so, adding dedicated lines is cheap and easy.
