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.

Larry- Can you use the DeZorel IN CONJUNCTION WITH the Equi=Tech?? I ask because I have ordered a Balanced Power Tech BPT 2.5 and am wondering if there is any benefit to 'daisy chaining' it with something else like a DeZorel. Are you using these two together?
Lak- yup- that was the idea. I currently have a Tice Powerblock IIIC HP. When the BPT 2.5 gets here, I was going to try plugging it into the Tice, then Tice to wall ans see what happens. With the Dezorel, it would be the same thing. What is the price on the Dezorel, and where did you get it?
Thanks for the info Larry.

Sean- some good thoughts. Unfortunately, living in a relatively new condo, I can't do anything about the breaker box and have to deal with the crappy power from the wall.

Furthermore, if you can believe this, the electrician who wired this unit actually put the microwave and kitchen outlets on the SAME 15A breaker as the entire living room!

I frequently trip the breaker just by having the tube amps on and then turning on the microwave out in the kitchen- brutal huh? Not sure if anything can be done about this as we can't rip through the walls of this condo, but it's kind of a drag...
