In Reply to: RE: I too think it is acting a bit like a voltage support capacitor in a power supply.. posted by Smelly_Socks on December 31, 2015 at 05:34:44
Well, I finally tried it out you bunch of lunatics! - on both my monoblocks, noticeable in a decent but subtle way, then on my dac - same thing but now accumulative and not so subtle and starting to render some spatial effects. Then finally a week later on my front end (flac streamer) Logitech Transporter - Now I'm thinking maybe the Transporter has a crappy ground plane because Holy Mother of Jesus, what a difference. The combination of all three is equal to a substantial capacitor upgrade.
Never ever heard my system quite like this before!
I'm running 9v little batteries on the amps, and big 6v lantern batteries on the dac and Transporter, 10,000uf Generic bypassed with Multicap film cap 5uf and a mundorf silver in oil 0.1uf on each.(all in my stash)
Sounds great - lightened the bass a little, used 4700uf at first but then 10,000uf (I think this helped with the bass but will have to compare again later) The BGT has really opened up the midrange and extended the top, but now I have spatial effects like nobodys business, quite incredible! Had given up that hi-fi could ever sound like this thought that was just a pipedream.
Has anyone managed to nail a special combo on the caps? mine are amazing as is but the tilt upwards, I can deal with but would love to be able to fill in the lower end too?
Maybe try the Raspberry Pi, and even my Router next?

I'm embarrassed to tell my friends, I'm just going to let them hear this
Follow Ups:
I have also used big 6v/12v lantern batteries but finally settled with standard 9V battery that is also very compact.
There are no additional benefits with lanterns.
After some experimentation, regarding the capacitors, I have settled with Rubycon electrolytics http://www.ebay.com/itm/1pcs-RUBYCON-16V-47000UF-L-ESR-Motherboard-Capacitor-30X50mm-NEW-m-/170753288169?hash=item27c1b067e9
and WIMA MKP 10 polypropylene capacitors that are very compact and very fast.
Silver wire, from the battery onward is also benefitial, IMHO.
I think it is better to keep it as compact as possible.
All of this led to even greater effect.
Believe Stu's website blog discussed the cap values that worked best.
For digital and video, around 100,000uf plus film bypass, along with silver wire.
Analog; around 30,000uf with film bypass.
The type (brand) of film bypass cap will affect the top end; warm sound signature cap will have less top end.
If I recall correctly,around .22uf was suggested for bypass.
This came up earlier in this thread; the effect of the BGT will be nil with a dead battery.

Please post a link to Unclestus blog, thanks...

go to his Blog section that is to the right end of the screen...
sorry, under the MORE section is his sub-screen blog...
So I removed them. Just a 47,000uF cap and a 9V battery works best in my system, wwhich already has plenty of high end. I notice a fuller bass/lower midrange and a little more dynamics, but no effect on the treble with this arrangement.
