Running both the Pi and Caiman II for about 12 hours from the Anker battery pack yesterday left it still with about 30% power, so pretty good results I think

I haven't been brave enough to try that....yet Must have a look in the instruction manual to see what it says about that :-)

Looks like it's possible - here's what the instruction booklet notes about doing so:
"When the battery's power level is below 30%, the multi-voltage port will not charge another device while the battery is being charged. The USB charging ports are not affected by this limitation
Simultaneous charging and discharging, although supported and not in any way dangerous, will slightly reduce the external battery's lifespan"

Interesting, Rob.. So it would still keep the pi going but not a 12volt supply. Food for thought..thanks for that great bit of info.

Hi,
FYI for those of you using new release 2.4, there is a network throughput issue due to old mount settings. It's particularly evident on WiFi connections. It can be fixed by clicking "Advanced options" when configuring a NAS mount and entering the settings below for Rsize and Wsize fields. Fix will b in release 2.5 :-)
** RECOMMEND REMOVE EXISTING NAS MOUNT AND RE-MOUNT WITH NEW SETTINGS
Rsize = 61440
Wsize = 65536
Note old settings: Rsize/Wsize (8048/8096)
Here is some test data from my network when performing MPD DB Update on CIFS/NAS based collection of 14,508 tracks, mostly FLAC. I'm seeing a significant improvement in WiFi throuput with the new settings :-)
Wired: 14,508 tracks, MPD DB update
- New 06 mins, 40 tracks/sec (1.17X faster)
- Old 07 mins, 34 tracks/sec
Wifi: 14,508 tracks, MPD DB update
- New 14 mins, 17 tracks/sec (2X faster)
- Old 26 mins, 09 tracks/sec
Regards,
Tim

Hi Tim.
Just a quickie if I may. How does moode determine the sampling rate? I just want to experiment with changing the sampling rate (or to not upsample at all using for example 44khz) but I can't find an option in Moode to do this.
Thanks
Josie

Menu, Configure, MPD
MPD configuration
- Resampling (choose a rate or "disabled")
- Sample rate converter (set to SoX: Very High Quality)
- APPLY
- Wait a bit for MPD to restart
If Resampling is set to "disabled" Moode leaves the samples at their original rate.

Tim

I decided to go with a dual linear psu. 1 side to do the rpi and the other to do the phono stage. Will let you know how it goes
