Well, some of the guys actualy visited the inventor at his place (that's where pictures come from) and were impressed to the point that decided to test the Ressurector in their own systems. The initial opinion is that the Ressurector doesn't "spoil" the sound, but adds more substance and synergy.
I know about one other person who bought it online, but didn't test it yet.

Just a quick update. I said that it didn't seem to matter where I located the phantom drivers. But I have since realised that it is quite important to keep the cables to the phantom drivers as short as possible, and better still, to use screened cables to connect them to the amp. Just how important this is will depend on the level of RFI 'polluting' your listening room of course. It does seem to vary in my case! 😉
open baffle implementation
Nuuk,
Interesting thread....I have few questions from your experience,
Is the effect of resurrector more pronounce in bass? How about the mid range up?
If I understand it correctly, you said that the effect of resurrector in open baffle speaker is less compare to the box sealed speaker?
Thanks,
Joshua

Hi Joshua,
The effect is mainly that the music is more musical if that makes sense. So it affects all frequencies.
I did think that the effect was more noticeable in my 'second' system that used boxed speakers. But the 'main' system (with the open baffles) is much better and perhaps something else in the system accounts for the difference.
If and that is IF the Resurrector works because of something to do with the movement of the speaker coil/cone, then one moving in free air (open baffle) may need less help than one in a box. But that really is me surmising rather than anything I actually know.
Hi-fi is such a personal thing that I really do hate to brag about mine. But last weekend, somebody came here to listen to my open baffles as they are considering buying the same Hawthorne drivers. This person was clearly a full-on audiophile with a lot of experience and he said that in his opinion, the Duets compared with commercial speakers costing in excess of 5,000 pounds. Was that the Resurrector effect or something else? Who knows? (Or is commercial hi-fi that bad? ) 😉 😀

I’m trying to understand here from your words above….if the resurrector works related to the movement of the speaker (probably is the one called ‘generator effect’?), would the open baffle speaker feel the effect more than the one in the box because it tends to create more generator effect in less acoustic damping environment/free air? So that in your conclusion : the ‘main’ system with the open baffle is much better…
I’m a fan of open baffle speaker too, so this might be a good news to minimize the trade off that inherently comes with open baffle setup….🙂…

Well keeping in mind it is theory, but you could look at it both ways. The cone in an OB has less restriction so MAY cause less of a problem to the amp. Or the cone in the box is more restricted and that may cause less of a problem to the amp.
But of course until we understand how the Resurrector works (if we ever do), it is all just conjecture! 😉
After quite a few years, and different versions, I am still committed to OB's! Much depends on the size of your room of course.
One other thought on the box v OB effect. I am using 8 inch phantom drivers that will probably be more like the 8 inch drivers in the boxed speakers, than the 15 inch drivers in the OB's! 😉
I use 12" open baffle's with monster back loaded horns in a very small room. I love going deaf and getting the "live" experience! Oh and I use a sub as well 😀

Its been a while since I've used a GC based amp although I have tried a number of different flavours of chip based amps so I was looking forward to trying the Resurrector , only other chip based amp I had to hand was a Mauro MyRefC based design in mono's
For the IC I decided to use the OPA541 with the Resurrector same as Nuuk, I've used this chip before and quite liked it
The rest is bog standard stuff, 1000uf panasonic FC decoupling caps, MUR860 diodes etc
The phantom driver used was the drive units out of my spare IPL S3TLM Ribbons
Line stage is built around Avondale 821 boards
After a bit of running in first listening test was done with the Resurrector disabled and using the fixed resistor instead of the phantom driver , this was done with a switch (as can be seen on Decibel Dungeon)
The sound was nice, decent quality with no nasties, the sound wasn't quite as big and a little flatter than the Mauro MyRefC amp, it wasn't quite as wide but it was still good .
I then decided to try activating the phantom driver switch
first thing thats obvious is the amp now sounds a lot louder and bigger! I started adjusting the gain of the linestage and marking the positions of the vol control to allow for quick altering when comparing the phantom driver against the bypass switch
Even when the gain was matched the soundstage was now noticeably wider with the phantom driver activated , the main difference to me though was instruments especially strings which sounded better, more 3d, with the phantom bypassed it sounded a little flat.
Midrange has a little more weight, vocals sound tonally more realistic to my ears
So does it now better the Mauro MyRefC? Well in all honesty I personally prefer the OPA541 with Resurrector + phantom driver enabled
I may try the LM3875 with the Resurrector soon but for now I'm going to live with it as is 😉
I'd like to say a big thank you to Marek and Nuuk for giving me the opportunity to try the Resurrector , I must admit I'm impressed and enjoyed what it brings to the performance
I've no idea how this thing works, I don't really care tbh, all that matters is that it does the job for me at least

Thanks for the feedback Leo. If anybody is wondering, Marek wanted to let somebody build a Resorrectored GC who wasn't a reviewer, and asked me to find somebody. I chose Leo because his opinion is much respected, and because of his vast DIY experience (much of it with GC's).
It was also a chance to have a Resorrectored GC compared to the Mauro GC that I haven't heard myself. 🙂

No problem and thanks again, what it did to the sound is enough to get me interested in the Gainclones again!
A piccy🙂
I used one of those capacitor clamps to mount the Resurrector vertical

I had another black heatsink spare so decided to give the LM3875's a go, it was a simple case of just swapping out one heatsink for another
I'm sure turning on the phantom driver switch now makes an even bigger difference when using the LM3875's in this circuit!
With the phantom switched off the sound goes flatter, less 3d, its less free from the speakers and seems to be thinner.
IMHO I think either of the chipamps gain more than noticeable improvements with the Resurrector

Sounds like ******** to me. The fact that its potted in rocks and resin is a pretty good indicator that whats inside is probably the same thing thats inside most other audiophile magic boxes. Nothing but a few resistors if you are lucky.
You know what you should do is this. Take your resurrector down to the local motor rewiring shop. They have solvents that will dissolve any resin known to mankind. Dissolve this thing and lets see whats in it. It wont wreck it, just let you see whats so "magic" about it.
From the article "In a nutshell, the function of the Resurrector is to reduce the amount of EMF that is sent to the drivers thus reducing the current inside driver coils of the speaker drivers."
There is another name for that process. Turning the volume down.
