This have any difference from one that available in aliexpress? External appearance is same...
What Josh meansYes, thistle correctly grounded whereas the stock Weiduka is not.
Too many changes. That happened along with it.Any difference in sound after introducing the Weiduka? You mentioned the hum has gone but any positive change in SQ?
I have Equitech which too has a balanced transformer. I can confidently say that you would like it substantially better than basic ones.Anybody using an isolation transformer like this one with toroidal transformer?

How does this compare to routine power conditioners, considering the efficiency of power conditioner being questionable? Advantages of going this route instead of power conditioners?
Can you share the price / link of purchase?I have Equitech which too has a balanced transformer. I can confidently say that you would like it substantially better than basic ones.
You will get past the bass/treble etc and realize how beautiful music starts sounding.
Can you share the price / link of purchase?
Apparently there's a good difference with Torroidal vs El Core transformer in Isolation transformers. There's a quite a bit of arguments in favor of each type of transformers. The Equitech looks quite steeply priced, whereas the local quotes are less than 20k for 1.5kva isolation transformer. Of course the quality and audiophile usage scenarios will be different.have Equitech which too has a balanced transformer. I can confidently say that you would like it substantially better
Do we have any reference for this <20mhz suppression? The chance of hum is more with El Core transformers but rarely with Torroidal ones. Again it's all from international forums so I'd be happy to learn.Balanced transformers cannot suppress noise to very high frequencies. Limited at max to 20MHz of noise suppression.
Isolation transformers on bigger sizes do hum but happen with most of the bigger transformers when DC enters into the transformer.
I doubt only power conditioner will have impact on all these factors, because other electronics and synergy seems to impart a lot of impact on overall SQ in my experience. I have seen systems sounding nearly ideal without power conditioners using exotic materials, correct me if I'm wrong. Power in music setup is like blood in the veins of body, runs from one end to other ; so purity of power will definitely have a impact on most of the elements. I'm really curious, what exotic materials, other than silver soldering, it'd be great if you could share (I completely understand the commercial reasons if you can't).What should be the result: It should sound clean but not sterile. It should give clear voices. Transparency increment and to be clearly perceived in airy highs. Even bass should have definition and rounded sound. It should provide an Inky black background to have a sense of space around instruments. All the above effect should not affect the dynamics. It was hard to design with all those things in consideration
We understand it is complex. Please demystify it with some literature that doesn't come under NDA.<snip>
Overall its fairly complex to explain. But its much easier to get something complete unit off the shelf than trying to build it as there are lots of pitfalls which might damage somethings or sometimes its life threatening.
I like this guyNot to derail the thread. But i use a Ps audio P1200 pure power regenerator and a isotek evo 3 Polaris power conditioner in my system. Power cables are also decent from triode labs .
And to my ears, neither of them make any difference to my power amps. I find that they have an improvement on small box components like my streamer, dac, router and preamp.
So in my limited understanding, it is my humble opinion, that components like power amps with their large transformers and huge capacitors, filter out the power gremlins on their own.
It is only small components like dac's and preamps, which don't have very robust power supplies and large caps inside , that can't filter power on their own and might benefit from external power conditioning.
I could be entirely wrong here. But the above is what I sincerely believe with my own extensive experimentation. Cheers...and please don't shoot the messenger
PS : despite my above observations, my entire setup is still driven off the PS audio p1200 power plant as it offers some stellar protection from all electrical power gremlins,including surge and lightning strikes
Hi Sandy....Thanks for your replyHi Newlash if you are not able to hear the difference despite of higher quality power supplies then its the speaker which is the culprit. If you have a really really high-end Ribbon-based tweeter and superb isolated speaker from vibrations. Yes, even the change in the power plug can be clearly heard.
Hi square wave...I tried both. Nothing ever makes the krell blink even once. Iam just posting a pic of its internals. Those huge transformers, one per each channel and 2 beer can sized caps per channel, can sort out the power for themselves.. neither the PS audio or the isotek have the slightest effect on them. And the same applies to the parasound too. No change at all direct to wall, or direct to ps audio p1200 or isotek...no change at all. That is the hall mark of a well designed amp I guess. They have to have robust and well designed power supplies to sort the power out.
