Having just loaded cMP & cPLAY I was checking the various diagnostics produced, one stuck out - the Latency on the EMU 0404 soundcard - the figures are 4858 and 4849. I take it that this is not good - what effects, if any, would I notice?
The sound quality compared to all my other digital sources is an order of magnitude better - so could it be bettered by changing to the Juli@?

In cPlay, goto Settings and select "EMU 0404 ASIO Settings" button (could have another description). EMU offers down to 2ms latency (default is 50ms). Latency's impact to SQ is explained here .

  cics,
  
  Lowered the latency to its minimum and got some playback problems - stuttering along it was. I have just received the Hypex memory and I will put this in and try again.
  
  I am still waiting for the Granite bits but I have some Skynet 8080 SMPS which I could use to power the HDD / Mouse Receiver / CDROM.

    Putting in the 2 x 512 MB low latency memory as suggested cured the stuttering / drop out problem allowing me to reduce latency to a minimum on the EMU card. cMP now sounds much better. However the EMU card still has latency of 250 - so perhaps I will just have to buy the Juli@.

      The SQ would improve even more if you use just one RAM module.

        I know that originally it was one RAM module and then it changed to two (specifically the Kingston Hyper X Low Latency) I must have missed the change back to one!

Never had any personal experience with the 0404, so I can't say for sure. However, the ESI Juli@ easily outperformed my RME 9632 on a properly configured cMP squared transport. That may give you an idea of the Juli@'s relative performance.
