The Taiko Audio Setchi groundboxes are not expensive and have very good performance/cost ratios.
I am using several of them in my audio system and have posted reports on WBF :

https://www.whatsbestforum.com/thre...x-has-got-a-big-brother-d3.25351/#post-507998

The Setchi groundboxes all contain a 9V battery. Taiko Audio recommends to renew it every 2 years :

However a friend of mine told me that despite his Setchi D3 was bought and used for 1 year only, there was a significant performance improvement when he renewed its battery last month.

Therefore I and another friend decided to do an experiment.
We bought several diff 9V batteries to try on a Setchi D2.
Please make a guess : which battery gave the best sonic performance?

The answer was : Energizer > Duracell >> GP.
:cool:

We didn't use equipment to test/measure them.
The judgement was by our ears only.
We don't intend to give any scientific explanation.

WBF members who are Setchi users please buy some other brands/industrial versions of 9V batteries and repeat the experiment.
It's fun!
;)

BTW some crossovers of speakers such as JBL Project K2 Series contain a battery.
They are for actively biasing the capacitors in the crossovers.

Some other brands such as Gryphon Audio Pantheon also have similar crossovers :

Any WBF members who own JBL or Gryphon speakers have done such an experiment/tweak too?
Please share with us.

That is interesting, we did test a few batteries but not the Energizer.

Is it possible to describe what sort of differences you are getting?

That Energiser bunny who keeps drumming just sounds better.

If bunnies decide, perhaps we have again a case of country dependence - US and Canada users should get Energizer, all other countries should get Duracell! :confused:

Hey, as a drummer myself, no contest.

FWIW, I know of a very dedicated audiophile who uses crystals on his gear and cables, some battery-powered, and he takes these discussions very seriously.

Solar panels? Wind-up handle? Hamsters in a wheel?

My friend is buying some 9V Lithium batteries to test but I can't wait anymore.
Just bought 3 Energizers for the 3 Setchi in my home (one D3 & two D2).

The effect is instantaneous : resolution/ microdynamics/3D image/ continuousness all improve.
Even though the overall improvement may be just 4 or 5%, what more can I ask for for the USD6 spent?
Haha. Very happy! :)

Eventually my frd and I got the Energizer lithium 9V battery!

How does it compare to Energizer alkaline 9V battery on Setchi?

I guess I may be talking too much on WBF for such a cheap tweak.
The Energizer lithium 9V battery is only usd8 per piece.
Pls buy one and try it yourselves.
You will be very happy!
:D
