Thanks for the information. I just wanted to be sure the USB Soundblaster was still not an option with KX, in case that had changed, before I ruled it out. I also was thinking I did not have enough processing power for an ASIO solution based on what I had read so thanks for the confirmation on that as well.
I'll probably go with a dedicated processing unit like a RF 3Sixty.2 and save my current laptop for use as a MP3 source only. I can run it through the existing HU. The RF processor has everything I want (huge EQ, 3-way active crossover, time alignment). The bluetooth Palm interface is very nice, and I already have a Treo 650.
I know I can get a lot of other functionality if I built up a PC (or bought a faster laptop) instead of buying the processor. But things like navigation, DVD, etc, in a daily commuter Miata will not be very useful for me, so I'll take the easy way out for now
