TX102 and DAC turbo (Off Topic)

Hi all.

Since I know that quite some guys here using battery powered DACs
and S&B TX102 I'd like to share two major tweaks I figured/tried out
during the last weeks.
For me these are a must and never ever without it tweaks!

1.
I just installed one Northstar 90NSB battery with an ESR of <0,003R to power my DAC and another one to power my Tripath 2020 based AMP.
(I know - Some guys would call it overkill - but keep reading below.)
It took me awhile to figure out what battery would suit best.
A car mechanic firing his 2000W rig with Northstar gave me that hint and
the convincing explanation. I thought by myself. What's good for a 2000W
Amp must be very good for a 20W Amp and DAC.

Before I was running a 25Ah and 10Ah Exide/Sonnenschein Dryfit A512.
The Sonnenscheins in general are rated to be the better ones.
And yes I agree. The sound was decent. Lets say I was not unhappy.

The Northstar battery can deliver short ciruit current of 4500A!!
and weighs 27kg. ( Be careful not to cause a short circuit!):wink:

I just can say. Battery and Battery. It makes a real big difference.
It'll blow you off. Its 180€ a piece if you're lucky.

I can understand now what the SMPS lovers were trying to tell me, when they
were saying batteries do not deliver the "Punch" or I would call it dynamics.
But these batteries, a little buffered and filtered, do. And they do it better, much better!

Give it a try! Its worth it.

One more:
Run your TX102 in Autotransformer Mode.
( I am wondering if that has been discussed here already)

It gives you more dynamics and resultion. That's what usually is critisised
about the TX102.

If you run the TX unbalanced try this. Just´connect your ++ lead of the
input to the 0db lead of the output. And listen! That's a ten minutes
0€/$ tweak. You'll love it. If you make it permanent you should take the
0db lead off the switch.

You'll find more Infos on DIY-Audio com. Just search for it.
But it is as easy as described above. Nothing more about it.

Bert isn't that something for your next audio gathering!

Feedback and other experiences on the subject are always welcome.
