Firewire to SPDIF

Does anyone have any view on the superiority to Firewire to USB in terms of conversion to SPDIF.

one negative of USB is that if you are using a SPDIF conversion device then using another device like external HDDs is not recommended. it is also limited to 48/24 ..both unlike Firewire.

the only good device seems to be the Weiss Minerva..but that in the Uber price range for something like this.

Does anyne have any experience with Echo Audio ?

Arj,

Pls also check your buffer size in the MAudio control panel. I use 512. Sync source is internal and spdif output source is set to mixer. I don't have the "disable direct monitoring" box checked. I am using WASAPI and JRiver 13.

Arj,

One more-from Maudio Manual
IMPORTANT: The FireWire Solo comes with a high-quality six-pin to six-pin FireWire cable. We strongly
suggest you use this cable, or one of equal quality, for optimum audio performance. If your computer is
equipped with a four-pin interface, you will need to use the included four-pin to six-pin FireWire cable.
Note that the FireWire Solo requires a six-pin FireWire connection in order to supply bus power; if you have
a four-pin connection you will need to use the supplied power adapter.

Cerrot,
Thanks a lot for the info

I am using a PCMCIA adaptor with 6 pin output. it appears to be thicker and of better quality, but will try the other cable as well
since a PCMCIA bus does not carry power i am using external power.

regarding the settings I actually increased the buffer to 1024, bypassed the mixer (since it is a winxp),

I was using foobar...but will try out J River as well !

will try to change it to your setup and revert back

Thanks again for the tips an the time taken to find the above info..really appreciate it

Arj,

Thank YOU for the tps. I just upped my buffer and bypassed mixer as well and soundstage appears deeper. I will do some A/P listening but, so far, think its a go. Think your issue is the cable and/or power supply. Please report back when you change cables.

BTW instead of using WASAPI you could use the M Audio FW as well to see if that is giving you any improvement.

I think the issue could be with the Firewire bus. I tried this out with my toshiba laptop which has a 4 pin firewire out and the sound became even more granular!. so that would mean that the firewire interface is perhaps a bottleneck.

BTW I tried the cplay player..very very basic but really good. am a bit busy at work the next few days but will try some more tweaking over the weekend.
