Have you removed Juli@'s analogue PCB?

  latency now at 48, analogue board off. Please remember I was getting some metallics from juli@ analogue outs with sox. Now nothing @ 64 latency.

    Got to shut down , going out for awhile. No metallics aftwer 1 hour.

          it goes an hour or so then metallicca. sorry I changed parameters midstream but I have been planning/building the battery supply for some time.
          
          Alfred these are LiFePO4 from a usa company in california.

            ...they are everything you said. Soundstage becomes large, hardness is eliminated, timbre is spot on.Thank you for this maybe best tweak ever on cmp^2.
            
            One interesting phenomena on the metallics... I am running 50% cpu usage with 192/-146 src but I think I remember usage in the 30% range yesterday before the batteries with src. I get mid teens with sox. But I thought cplay 2.0b27 was an improvement on efficiencies. Can someone who is running 27 with 192/-146 src get a read from task mg on cpu usage? Certainly 50% usage was consistent in the past with metallics for me so that is not a surprise.

              ok now I'm getting 25-27% cpu usage with src @192, what the heck would cause it to jump to 50% before??

                I have gone 1 hour src / 192 no metallics @ 25% cpu usage. But but the sonics of the battery are overwhelmingly great---several discs I heard as if the first time. One is a classical piece wherein the depth gets 30-40% deeper. Another one with 2 female vocalists singing 'Walk away Renee' it sounds as if they both stepped forward several feet into my room. The air around them is uncanny (you can hear around them). Alfred thank you again!!
                
                Maybe after I modded my juli@ for batteries it takes several hours to settle. I believe now I can use cpu usage as an indicator of whether metallics will come. If its 50% they will come if 25% they will not.

                  2 + hours no metallics

                    6 hours on src 145 / 192 sample rate / 48 latency on juli@ and small buffer on cplay---no metallics. The metallics I suffered from earlier was probably due (I'm surmising) to the soldering on juli@ not settled in yet and the power supply being off while I modded the sound card.
                    
                    It was really unusual that I was getting 50% cpu usage (when metallics ocurred) and now I'm getting 25-28%.
