Hey theob,
Indeed a very interesting piece of gear you´ve found.
If the device really operates asynchronous ( in my understanding using USB directly on the BUS level) it could be an alternative to certain I2S setups requiring/accepting 384kHz samplingrate.
-on the other hand, every PCI or PCIe device grab´s signal processing on BUS level.
I´m not sure about the digital crossover ability you´re mentioning.
Of course you can split the frequency bands and route them to two different DACs, but then you need to clock-sync these.
With two regular DACs and a clocking device it´s gonna be an expensive solution, yet compromised one.
-and a multi-channel D/A converter interface will most unlikely accept I2S.
In my view there is no quality alternative to digital crossovers with cMP than the route I´ve followed for some time.
I´ll repost my tread on this.
kind regards

I greatly appreciate what you have accomplished...my only problem is I'd have to buy a new soundcard with 6 outs to do it. I'd sure like to know more about your setup though.
Dear theob,
for anyone that plays around doing something similar, the best entry level is a RME FireFace 400.
-it has FireWire connection; it´s external; it has a decent quality; it can be powered from an external power supply and can be found 2nd hand....
In the recommended Gigabyte boards, FireWire can be slotted straight into the motherboard, as these have the "must-have" Texas Instruments EEE1394 chipset.
If you´re considering an internal soundcard to begin with, make sure it doesn´t conflict with cMP optimized BIOS and PSU requirements....
kind regards

I really wanted to get away from another soundcard but you given me something to think about.
Hey theob,
hehe...that was un-intentional ;-)
When cics launched the cMP project, there were hardly any FireWire DAC options and no asynchronous USB devices either, but once cPlay is connected directly with a FireFace or an Aurora via ASIO, you´re circumventing a lot of what cMP is about : Jitter !
With FireWire and the appropriate driver the entire clock-stability becomes business of the external device.
kind regards

Thanks Play-mate
