DAC turbo (Off Topic)

Hi Steve.

Its all about the batteries ESR. I'd guess that your battery still
has 20-30mR ESR.

Unfortunately it seems that one needs a real big battery to get that far
down. But I figured that every mR counts on the supply rail.
Without switch and connector it was perfect. The pity is - there is no way
around these you have to have them in! It is just do dangerous without switch and connector.

I am buffering with 8*470uF + 0,2uf (BG NONpolars) and a 1000pF ceramic (0805 Type with silver leads - DIY).

Hi Klaus,

I noted a good improvement in dynamics and quietness upgrading from 7Ah to
24Ah powering my DDDAC1543. Now you tell me there is much more.

But these batteries, a little buffered and filtered, do.

What buffering and filtering arrangement do you use?

Best regards
Steve
