Grounding boxes - The real deal

[willbewill]

They are not measurements of Tony's product though. That's the Entreq.

Also no-one here is saying that one actually does anything (unless I missed it) wheras the Tony box generates immediate and obvious improvements, according to the witnesses.

Exactly and I trust Alan's opinions...but I wish I could get my head around what is exactly happening.

Beware. There is a danger of trying an RTZ in your system

The difference between my Rega Isis, Belles Pre, Monos set up and the TAD set up I now have became *much* greater and persuaded me to go all TAD. Left a very large dent in my savings.

C'mon Mike

All I can comment on that particular set of results which are being used, the test was not valid!

"Wait, but you are bound to say that". you are a manufacturer of said devices.

Hold on for second, the test shows an INCREASE of +30dB on the noise floor , now NO one in the right minds would put in ANY piece of equipment that would cause a sound quality derogation of that magnitude

I'll expand, the signal to noise ration of a top notch CD player really is so close to 96dB, by the test results the resultant conclusion would indicate the SQ of the system it was plugged into would drop below cassette tape playback capability

Some how I feel no one would wish to 'achieve' that sort of a 'upgrade'

The test is also floored for one particularly large reason, it bears no real ability to demonstrate what is happening in an actual working system that is being used in a domestic environment.

Now please do realise I do not retail Entreq, however I have listened to this product in many systems and many levels, and NOT once have I been party to that kind of sound quality degradation what so ever.

This is not a end run around the question for measurements just an observation. I would also further suggest that a number of products which have the similar results also partake said request as well. Currently this is being pointed squarely at our products I realise that is because they has been a lot discussed about them, though this is purely from customer feedback and various visits from a respected forum qualified engineer and others.

You could also apply the same ideals to all cables etc. The cables that attached to the GB's are of a very low, capacitance from 12-22 pf per m, inductance and resistance. Does any of this bear a quantifiable and REPEATABLE up grade in SQ when applied to audio system, the debate is long and wide and several miles deep with both sides intransigent (the irresistible force meets the immovable object)

So lets have some suggestions as what you wished to measured?

It was 40db but still at -110db so not the level of degradation you allude to above, no need to roll the eyes.

Surely you want to be measuring signal to noise in the system across a range of volumes with and without the grounding solution attached....?

[willbewill]

Please bear with me if what I ask has already been covered...but I'm trying to make sense of it.

I assume the cables are only connected to the 'grounds' of the rca connections on each piece of equipment?

I also assume it is assumed that most, if not all, of the interference noise is to be found on the ground planes, either from external RFI, mains noise and internal circuit/power noise. It would, I assume, be difficult to differentiate between signal and noise on the signal side of the circuits?

Therefore the 'ground box' 'drains' this interference noise from the ground planes thus 'freeing up' the signal, giving greater clarity/transparency which manifests itself in increased soundstage etc? I have experienced this in the past with 'dirty' mains supplies, even down to a Lenco turntable having its power supply being provided by a speed controller instead of directly from a mains supply where everybody in a room jawdropped when they heard the difference...most of them did not even know it had been changed but heard it.

That's pretty much my plan too.
