Review: DeZorel G2 AC filter

Mini Review of DeZorel G2 Line Filter by Lak

The DeZorel (several models available) is manufactured in Yugoslavia. It appears to be a frame beam case construction with a filter module that is made of custom cast aluminum boxes called a “Brick.” The Brick houses the actual filtering components, which are epoxy resin, closed from the bottom side.

THE GOOD STUFF

After using the DeZorel in my system for one week and a few days (I only needed to hear it for one session), I wholeheartedly recommend this product. I tried it with every possible combination within my system and regardless of where I placed it, there was improvement: blacker background, more detail, better depth of field, more dynamic bass and soundstage, and overall musicality. I also liked the thermal resettable fuse switch. Although the unit never shut down, all I would need to do is wait a minute and push the button back in.

I liked the DeZorel so much I was able to purchase a demo unit. I even heard an improvement when utilizing the G2 on top of my 240/120 Isolation Transformers that feed my dedicated sub-panel from my main panel.

Advantages I detected:
1) Extraordinary power line isolation.
2) Improvements in clarity, imaging and low-level resolution, and in some cases all resolution.
3) Suppresses digital, RF, ground loop, and switching power supply noise.
4) Significantly decreases leakage current and noise between equipment.

Hi Sutts,
Yes, you can daisy chain the two together. In most cases it's an improvement, in a few situations there is no improvement. This did not happen to me, but be cautious that the DeZorel (or any other device) does not limit (choke) the music or component.
Another avenue to consider (that I did not discuses in my review to keep things simple) was filtering power with the DeZorel first and then plug the Balanced Power Tech BPT 2.5 into the DeZorel, assuming your not drawing more power than 2.2 KVA.
I would love to purchase individual bricks and run each of my dedicated circuits through a brick at the sub-panel level for filtration purposes.
The DeZorel might (?) be better than the Tice Powerblock, I don't know, I never owned a Tice PowerBlock. I know the TPB does something different than the DeZorel. The DeZorel only filters whatever power goes to it.
Try the TPB and see how well it works, it might be fine!
