Hi Stu,
What you says remind me that:
Follow Ups:
wasn't aware of them before.
The ratio of ground to positive I have been experimenting with for the past decade, actually. The enhanced ground concept, well I have the BGT's.....
The key to all this is ground wiring and networks are crucial, but too many simply run a bus bar and consider it done.
The metals used are also interesting.
On the tables of electromotive force, copper ranks very high but silver and gold even higher. These larger and heavier precious metals have larger valence shells and thus I believe can emit more electrons.
Checking out the concept was ridiculously easy. Took the wife's wedding band and hung it on an RCA barrel. Better dynamics and fuller deeper sound. She wasn't very happy, though, with that idea.
In building various BGT's, i now modify construction for the intended component. Digital and video I use silver wire and that make a vary nice difference, although for the copper analog construction the difference is minimal. I use a thin strand of neotech 6N silver along with more conventional thicker silver. Bypass caps also need to be smaller to accommodate the higher frequencies.
With gold back up to $1900 an oz i am not so eager to play with gold. although I do notice 24K gold leaf is still relatively cheap.
Enjoy
For gold you can buy cryo occ gold plated enamelled wire to clairvoyant audio: a very good wire for audio and gold coated!
In a fishing shop you could consider some tungsten wire wich is very good for the highs...
After the first trials of you BGT which I built with some "kitchen table components" I found sound was to bright and used 22uf 63v ruskies caps to tame it a bit. Now it's good and I'm waiting for components I bought via ebay and particulary big silmic II electrolytics...
You'll find the BGT is a easy way to evaluate Power supply components. How it affects the BGT is identical to how it'll affect a component
I use 50,000 uF minimum and 100000 uF for video digital
Have fun
this one uses huge magnets:
Hi Stu,
Did you ear improvment of this kind of devices whic is said to improve the ground?
Hi,
I've happened to try the BGT against the Entreq Tellus and Minimus (which I happen to own). Although you can still hear the effect of the BGT, its potency is diminished compared to systems with no form of ground tweaks (like my other system which has no ground products at all).
In my case, the BGT is a 9V battery and 10,000 uF. I've mainly experimented on the lower end of values (4,700 to 15,000 uF), but I will be trying out higher values over the next few months.
Hi Aupiho,
Sorry, my fault. I realised I could have been clearer in my writing.
What I meant to say is that in my system with the Entreq Tellus and Minimus, the BGT tweak has a much smaller effect. This was also my experience in using other ground devices such as the Acoustic Revive RGC-24 and the Audioprism Ground Control.
If I take out the Entreq from the system, then the differences with and without the BGT are quite obvious.
The BGT is not able to approach the effect of the Tellus, Minimus and the matching solid silver cables, but bear in mind that for $10-20, the BGT can provide results that can maybe achieve 30-40 % of the Tellus.
You can't really go wrong with the BGT for the price, although I did find that you must experiment with the amount of capacitance to get the right tonal balance.
The Tellus and Minimus really improve the 3-D effect of a system and improvement of resolution all round. In comparison, the BGT at lower values adds a smoothness and blackness to the system. To add extra pop and high frequency definition, you need to increase the capacitance. I made this for a friend by building the circuit in a small plastic box, and terminated with a speaker cable binding post (so that he could use any cable he wanted). He said that the cable is critical, and he got much better results using a solid core silver cable, compared to the copper solid core cable I provided to him.
Hi watchdogsg,As i said previously to UncleStu
"On the web I found that a brand was doing ground tweak for lousdpeaker outputs with 8 feet copper ribbon. I have 1.5mh 0.3 rdc ribbon coils from an old projects and decided to plug one coils to each - pole of speaker binding posts in conjunction with bgt: it improved it a lot going deeper in the midrange region. (just one end of each coil was plug to the post the other end remained free, floating!)"You said that tellus bettered of about 40% the BGT, If you have such a ribon coil try it; I think the gap between BGT+ribon coil and tellus will be seriously reduced!
Bud Purvine said his ground control was better when made of litz wire with a max of little strands wich makes me think that the litle amount of capacitance added on the big area of all this strands was acting like an HF filter.
So the key seems to have a large copper contact with insulation: the same thing occures with a ribbon and its large contact area! In my cas it's a 14awg ribon.When I look to the core audio claims they say their ground conditioner is the heart, of a new star grounding for all the system!!! They claim their conditioner is a 0 impedance grounding: without, it would be a disaster because it would create multiple ground loops.
Maybe the best thing would be a 0ohms ribbon coil+BGT wounded on a magnetic material: only one ground for all the system. But where to find such a coil???

I beg your pardon but english's not my mother language and sometimes have difficults to understand.
What do you say? BGT is better equal or less good as tellus?
Do you use BGT with or without tellus?
What's the difference in sound effects you can hear between BGT and Tellus?
Tell us! lol
and the patent of the Eichmann ratio too:
