[Doc B]

Woo hoo, the first of the Bottlebatts shipped on Friday! More are under construction today and there should be more shipping throughout this week.

Got the battery kit today. Seems to come with a charge as I've been listening on bat only.
The sound is awesome! Listening to Jenna Mammina event 37 from Blue Coast.
Its 5.6 Mhz Dsf and plays with hiss through Amarra, but fine through Audio Gate.
Using USB input on the DAC.

Seems to come with a charge as I've been listening on bat only.

Yes the batteries have been measured at about 6.2 to 6.3 VDC when they are packed.

I should point out here that these supplies are not like iPhones where it's recommended to run the battery down all the way before charging in order to extend the usable lifetime. These are SLA batteries and thus they can be left in charge mode as much as one wants. There is no advantage to be gained in terms of lifetime by running them until the DAC dies. In my system the sonic difference between using the stock line lump and the battery supply is significant. Whether the battery supply sounds better in bat only mode or bat/chg mode is much more subtle and might not be easy to discern in a lot of systems. The difference is subtle enough that I usually forget to switch to bat only mode and thus most listening at BHQ ends up in bat/chg mode.

Thanks for the info. I had trouble telling the difference between charge/bat and bat as well.
I thought it was that I was not standing in the sweet spot as I was switching back and forth, or
my hearing, which is fading. I didn't try the comparison between wall supply only and bat kit.
