I bought an Apple TV-X and it arrived the other day. It is an improvement over what I was using but I'll have to get out my original A2169 and compare it to the latest ATV again to see how far off I was. I use Sony A90 OLED and Sony 760ES laser projector and it was more than just me...
I understand the differences in hardware between the A2169 and latest Apple TVs but in my theatre I always felt that the latest unit gave a better picture than the A2169. Could it be that with lower power consumption and less RFI caused less problems than the earlier versions?
An old thread but I wanted to recommend the M-pods as a most worthwhile upgrade tp the S7's. We can argue about price and whether they should be included as standard, but the fact remains that they lift the performance of the S7s so much that on a performance - increase - per - dollar basis...
I was told that these were M-Pods by the owner but now I'm wondering if they are in fact S-Pods. Magico do not actually identify these as a particular type of pod but refer to them as "M3 Spikes". They have 2 types of spikes, one for carpet and the other for hard floor. Could they just be...
I don't think it has anything to do with costs savings but everything to do with the M-pod effectiveness. Firstly, the addition of spikes will allow for excess energy that cant be dissipated quickly enough by the pods to be dissipated through the spikes. Secondly, it may well be that the...
I noticed Magico's latest M3 incarnation is using spiked Pods instead if the smooth faced ones that they used originally. They have also done away with the outrigger stand.
Some pictures from the new M3 owners manual.
With the outriggers gone, they are shipped with these temporary...
I think the lack of specs could lead to problems. For example, I was considering purchasing a Vitus power amplifier using a tube preamp for the near future until I could upgrade. However I discovered that the input impedance of the power amp was only 600 ohms , which would not have been...
Hi Pcosta
I know you are looking for a practical solution to your problem so I'll keep it to the point and hopefully others may do so also.
If the Equitech unit did not help with the hum then the MGE unit will not either. The Equitech , apart from being balanced with centre tapped earth is...
Generally the manufacturer would specify "balanced isolating" rather than just "isolating" transformer if it was a true balanced design. Balanced transformers are also isolation transformers ( but not vice versa) so you will get additional sonic benefits above and beyond a standard isolation...
Irrespective of quantum, common-mode noise poses a greater threat compared to normal-mode noise because of the different path taken to dissipate the noise energy. I would say that is the reason that companies like BPT and Equitech have satisfied customers. Transformer manufacturers can also...
You described your earlier post as pedantic and i agree with it. All the transformer manufacturers describe the balanced transformer attributes, as cancelling common mode noise through combining 2 out of phase voltages. Describe it as you like.
As far as teaching Grandma to suck eggs , it is...
That seems like disinformation to me. I am trying to pass on experiences to fellow audiophiles, if you have something to sell or a vested interest , or simply a favoured approach, you should just say so that other people can benefit, Throwing theoretical negatives around serves no helpful purpose.
Hi Paul
I did misinterpret what you said in regards to leakage currents but common mode noise rejection is not performed by isolation transformers, only by balanced isolation transformers.

The power from the wall has the sonic signature or coloration of the power company's neighbourhood transformer, the power lines in between and all the pollutants that are present in the grid. It is by no means a neutral starting point. So any departure from that does not mean the transformer...
I am talking from experience and practical experiments only. Theories of what causes which effect are fine but we shouldn't dwell on them for for too long without undertaking experiments to test those theories.
For that purpose, a group of us in my neck of the woods ( Western Australia)...
Great theory - But in the real world when every single item of equipment in the audio chain does not have adequate mains noise cancellation or DC rejection, you all always get an improvement with these devices. In any event, no item of equipment will remove as much mains noise as it would a...
Hang on a minute! So is the proposition that removing common mode noise ( the greatest pollutant present in the electrical grid in my experience) and DC ( transformers cannot pass DC) from the mains power line = sonic coloration? If so we had better inform many of the worlds leading...
I am the S5 owner referred to by Peter and I can reiterate that the service from both Magico and the dealer was simply superb throughout. It seems to make make no difference where you live or who's fault the problem is because Magico instantly respond with a solution. It gives you such...
"Symmetrical balanced" transformers, balanced power supplies etc are all in fact toroidal isolation transformers with a centre tapped earth. The fancier the name and the prettier the presentation - the more expensive the price, but they are all as I described. Being toroids, DC will make...
As you know transformers cannot pass DC and they vibrate as a result which causes humming. An isolation transformer will also hum if DC is fed to it. It will only isolate ground loops and all you will be doing is feeding it DC rather than your amp T/F. Lighting dimmers are big culprits for...
The ONLY place I buy transformers from is the UK. Absolute first rate quality at non-hifi prices. For around $1k, you can get a 5KVA balanced and isolating transformer. Stick a hifi label on it and you pay upwards of $5 K. The balanced transformer does about 85-90% of what a PS Audio P-10 does...
Placement will depend on room size and orientation and listening distance.. In my case i have found a distance of 1.32 metres measured from the point closest to the listener to the back wall is quite good. i have read a review that said 1.5 metres- that is good too but a I detected a little...
