This combo at src/192 is nothing short of amazing, I just love it. Imaging, dynamics and a sense that a light is turned on at the back of the soundstage---so much more to hear but smooth, very smooth. Congratulations.But I have some questions regarding some anomalies. I get zero metallics but I do get an occasional what I call a 'static-ee' noise which goes away via going to another track or changing sample rate. Others get this as well. I got the same noise when I was running juli@ analogue outs. If metallics were a 10 as an issue the static-ee is a 3: far fewer and easier to fix but annoying just the same and does not require a reboot. So upon throwing this around in my head I believe it may have the same root cause as metallics but since the system is no longer using juli@ drivers it is just manifested as
different. But assuming this is correct here are some more observations: when I get the static’s my cpu usage is typically 50 % with spikes up and down. But since Sunday when you asked me to run 48/tiny I have gotten zero static’s so I thought it was the combination of 48 / tiny parameters that was doing it (and maybe it is) but I also checked cpu usage and I'm back down to 25%. This same phenomena occurred back in June when I was running spdif out to the Benchmark: for a wonderful week I was getting no metallics while getting 25% (when prior to this I was getting 50% cpu usage and lots of metallics). So I think there is still an issue with juli@ (albeit minor with I2S out) that is somehow associated with cpu usage jumping around from 50% to 25%. This am I had to reboot after being on for 3 days and upon reboot I got 25% cpu usage but with spikes up to 45-50%. After being on continuously for a while the spikes started to settle down in the 35-40% level but come back to a higher level after not running cplay for a while but with the pc still continously on.Edit: my mistake on the cpu usage bit, I found out my pc reset unbeknownst to me my bios hcc to auto and I got clock speed of 1600 when I reset back to 840 cpu usage goes back up to 45-50%. When I reboot I normally sense a reset of bios when It takes long to boot up, I missed it. I hate computers. I love cplay/cmp.
Not to throw cold water on my glowing review of cplay 31 @ tiny/48 (and it is nothing short of magnificent) what in your opinion could be happening here with the noise issues and cpu usage which seems to be correlated. Look if I had to live with this situation as it is now I would be happy for a long time. I'm just trying to understand if juli@ is fatally flawed and whether I should pursue another sound card. I was tempted by the Lynx but w/o anyway to run battery power or I2S out I fear the Lynx may be too limiting now that I have experienced LiFePo4 batteries and I2S out.
