AND, the only component that I had plugged into the DeZoral was my Mensa DI/O dac. Why? Because unless I wanted to undo a lot of wiring I had to chose between plugging in the dac or plugging in the pre and amp. Since my amp supposedly has very good built-in power filtration, I chose to plug in the dac. My frame of mind right now is, imagine how much better the sound would be if my Cary (used as a transport) and Joule pre pre had a DeZoral filter upstream... (I'd also plug in the amp to see what happens).

Jay, you are the only one so far that has done a *proper* evaluation of the DeZorel. You only plugged ONE component and it happened to be the noisiest component in a system, the DAC. The only other component I would try to plug in the same module would be the transport--maybe.

Excellent!

Hi Jay,

Here's a very big thanks to Guan for lending me his LF-P1. And, no, you're not getting it back too quickly!!!!!!

You're most welcome and congratulations! Another happy DeZorel user..

You can keep the filter until you get your AR Senior. I'm just glad I loaned you the LF-P1 and not my AR Senior....can't bear my system without it

It's definitely exciting that you get this much improvement by only plugging in the MENSA. Imagine connecting the Cary also....tonight, tonight!

And I'm quietly confident that the SlinkyLinks silver cable will add yet another dimension of detail and liquidity to the sound you're getting.

Just a technical detail, apart from the Acme sockets I also have wired in parallel a IsoClean 24K gold plated UK type socket which I am currently using to power the AR Senior. So if I could be bothered, I could replace the plug on the DeZorel and compare the differences between the gold plated IsoClean and silver plated Acme. I will probably need Jay's golden ears again for this test!

Completely afreed! Let me just add that in case of multiple filter units, the best way to evaluate them is to start with just one component, listen, then plug in another, listen again, and so forth until your whole system is plugged into the filter. That way you get a better perspective of what reacts how much.

An alternative would be to plug in one component, then unplug it and plug in another, and so forth. This is longer, but more revealing of which part of your system is suffering the most with polluted power lines.

Obviously, you would do this only once, after which you'd leave it all plugged in for good.

For the masochists out there, there's what's called a negative test. This is to simply take the whole filter out and use everything without it after you have had the filter in circuit for say a month. That gives you an idea how other people have to make do and underlines why you need that filter better than anything anybody could ever write.

Cheers,
DVV

Psychicanimal,

Your comments about Jay doing a proper evaluation by testing only one component with the filter at a time make perfect sense to me; however, I get the idea your advice/comments extend beyond the evaluation phase and into everyday use. Do you feel it's best to use a dedicated filter or isolation device for EACH component? If so, what would you recommend for the average system (say under $5k) where a person plans to spend no more than $500 on power?. I've been thinking of doing something like a BPT Jr. for my front end leaving the amp plugged into the wall or maybe a used PS Audio UO if I find one, or the small DeZorel with a good power strip for filtering everything. I get the idea you think this is a bad idea, but better than nothing? I believe some devices like the 15 amp Exact Power voltage regulator are designed for the entire system, but that's more than just a filter I guess.

Jay, others, do you think you should post a review of the Dezorel in the Critic's Circle?

A dedicated filter for each component would be the ideal scenario, assuming that they are indeed needed and that one can actually afford them. That's what I do. Can I afford it? No. I was just fortunate to find that Clear Image T4 for a ridiculous low price in eBay (under $500) and a friend sold me the big 95lb 220V ONEAC for $100.

To answer your second question, If I was in that situation I would *build* myself a power strip wired in parallel using cryo'ed receptacles and plugs, if possible. I would plug it to a DeZorel in the specific order described in the NAIM website. It would be less than ideal, but still much better than trying to plug everything into one or two modules and ending up cross contaminating the current. In this game, cross contamination prevention is just as important as input current filtration, IMO.

Given the fact that we use 110V I find big 220V in/ 110V out isolation transformers very helpful at giving equipment, especially power amps, the *juice* they need. Sean of Audiogon/the Asylum says so too, as well as the Bear (www.bearlabsusa.com). I hold high esteem for both gentlemen.

To isolate components you could also try a DeZorel with >1 brick and plugging the components you want to keep separate into outlets connected to different bricks.

I am planning on ordering an Audio Reference Senior or an LF-A4 Mk II (4 0.1% tolerance bricks like the AR Senior but not cryo treated). Each of 3 bricks would be wired to a duplex outlet; the 4th brick would filter the ground. Here's how I am thinking of connecting my equipment:

Brick 1: Transport, dac
Brick 2: Tube pre
Brick 3: Digital amp

I will likely also plug my dvd player in brick 3 (#3 better than #2 as the digital amp has built in power filtration) and my tv into brick 2. Both of these components are usually turned off or on standby.

You could achieve a similar degree of isolation with the LF-A3 (3 bricks); you would just give up the filtered ground.

My digital cable box, cable modem and wireless broadband transmitter would be plugged into a cheap-o extension cord in a separate outlet from the DeZorel.

HELLO...

WHO HAS THE DEZOREL NOW?

Not me....

>> WHO HAS THE DEZOREL NOW?

I believe Randytsuch is the one... and I'm next on the list

randytsuch · « **Reply #131 on:** 23 Jan 2003, 11:46 pm »

I might have it. I looked when I got home last night, and no package. I checked the Fedex website this morning, and they said they delivered the package, and left it at my front door last night, at 8pm, which was after I got home. I was upstairs giving my kids a bath, so I might not have heard the doorbell. Hopefully, it will be there when I get home tonight. I won't be home until late tonight, so I won't get to listen to it until Friday night. Hope to send it off early next week.

OK, I have a box that smells like smoke, it that it?

Seriously, I did smell cigarettes when I opened the box. Will fire it up tonight, and listen to it over the weekend.
Oh, and the box is OK for now, but I don't think it will survive another 10 shipments. Somebody is going to have to get a new box for it before this is through.

Randy

nathanm · « **Reply #133 on:** 24 Jan 2003, 04:44 pm »

It STILL smells!? Sheesh! Maybe someone should swap the styrofoam with potpourri! Maybe the cigarette smoke film is burning off the parts inside as they get warmer. Heh! It's a good thing DeZorel doesn't make microchips! I figured the box would not last long either. I'm all for recycling and all, but recycled cardboard is damned flimsy.

JoshK · « **Reply #134 on:** 24 Jan 2003, 05:17 pm »

Randy,

Do you happen to remember what number you are in line?

randytsuch · « **Reply #135 on:** 24 Jan 2003, 07:08 pm »

Josh,
Think I am 4th, Jerry, Nathan and Beezer have had it so for. After this, I send it to Dino, than I think it goes to Bubba, not sure where it goes to after that. Between shipping and audition times, don't expect to see it anytime too soon. Speaking of shipping, I was not impressed with Fedex ground, Beezer sent it from N. Cal on Friday, and it took until late Wed. for them to get it to LA.

This is my complete Dezorel signup list and planned order of auditions; sorry but I don't have everyone's audiocircle member name:
1. audiojerry, Wisconsin (done)
2. Nathanm, Wisconsin (done)
3. Beezer, California (done)
4. Randytsuch, California
5. Derrick N, California
6. Brian S, Seattle
7. Mike G, Englewood CO
8. Mark J, Salem OR
9. Mark C, Ontario
10. Briley, Greensboro NC
11. JoshK, NY

Maybe, each member could copy this list, and post a rating of 1 thru 10 as a quick reference for someone reading this thread. For example, here is how it might look so far:
1. audiojerry, performance = 9, value = 10
2. Nathanm, performance = ?, value = ?
3. Beezer, performance = ?, value = ?

Nathan, and Beezer, maybe you can each copy and paste this format, and then enter your own ratings.

bubba966 · « **Reply #137 on:** 24 Jan 2003, 08:02 pm »

Actually I think OBF gets it after Dino. Then I get a hold of it when OBF is done. But I can't remember who gets it after I'm done with it.

Does someone have a "master list" for the shipping order?

nathanm · « **Reply #138 on:** 24 Jan 2003, 08:15 pm »

1. audiojerry, Wisconsin Performance = 9 Value = 10
2. Nathanm, Wisconsin Performance = 5 Value = 3
3. Beezer, California (done)

6. Brian S, Seattle
7. Mike G, Englewood CO

I'm the only one with the 'master list', since it began with me. I came up with the shipping order based on when deposit was made and geography.
Of course, I have control over nothing.
