Hi Peter,
I noticed that double arc prediction upsamling of hi-rez material (24/96 -> 32/192) causes small dropouts every minute or so while more cpu-consuming (is it?) quad arc prediction of hi-rez tracks (24/48 -> 32/192) plays flawless. I'd appreciate your comments on that

Another log, this time easier to figure things out - first track, first minute. Playback stops, XXHE goes back to Attended. This happens regardless of buffer size and sample rate used. Sometimes I can play whole album, but in most cases I can't get through it. Very annoying.

Ultimate Audio Playback / Your thoughts about the Sound Quality / Re: SQ differences in priorities, buffer sizes and split sizes - breakthrough

I played around with different firmwares and drivers from few vendors and here are the results of my battles: * drivers affect SQ and it's not a small impact * there is no 'gold' rule for best buffer size (regarding SQ), core appointment schemes etc. For example; ESI firmware and drivers sounded the best with lowest buffer size (48 samples) and scheme 3, but with 2 CPU cores activated! (Roy, I perfectly understand your disappointment...) Although low latency playback worked great with ESI software it didn't sound 'right' for me - to analytical/technical/clinical (pick whatever you want). Eventhough everything seemed to be there, great, punchy bass, lots of details, but I missed the flow of Cantatis/Via drivers. In other words, I couldn't find the setting that would not 'hurt' my ears with ESI soft. All and all I got back to Cantatis software (older version based on VIA 5.20 drivers) which sound the best for me and my girlfriend, who is now sleeping like a child and not complaining about loud music

Ultimate Audio Playback / Your questions about the PC -> DAC route / Juli@ owners - heads up!

I've just flashed my Cantatis Overture sound card to Audiotrak Prodigy 7.1 hifi and it's working! Native ASIO drivers and KS work, even with 48 samples, There is one problem though:
- 44kHz (88,2,176) playback works, 48kHz (and multipliers that is 96,192) don't work properly. It's like listening to music in 'slow motion'. I guess that Prodigy 7.1 hifi has different clock on board for 48 and its multipliers.
I'd be very greatful if someone with Juli@ card could take a picture of EEPROM offsets. Juli@ has the same clocks as Cantatis, so my assumption is that it'd work for 48kHz playback as well.
* In order to do so, you need to run eeprw.exe (enclosed) in 'real' DOS mode, press 9 and take a picture of Juli@'s offsets. That's it, it'd take few seconds. (enclosed you will see EEPROM for Cantatis. I need offset values for JULi@)
* Note that eeprw works only under 'real' DOS mode, you can't run it from windows. In order to run DOS, there is a tool called HP USB Disk Storage Format Tool + win98boot files (enclosed). With these 2 things you can prepare bootable usb flash. After a 'start disk' is created, copy eeprw to your flash drive, restart pc and boot from it.
Thank you in advance for help, Marcin
