How good are the various FW cards for PC slots?

I have a good, fast machine, but there's no FW interface on it, and I have access to a few pieces of gear that use FW as the connection that I'd like to try.

Hi Guys,

Are there any advantages of going through a mixer and into a PC via USB? OR would I be better off going directly from a mixer and into a PCI card via audio ports?

I have purchased Mytek Stereo96 DAC, and connected it to my MOTU UltraLite mk3 Hybrid .
I was totally blown away by the improvement this little Mytek DAC gave in sound quality .
But the dealer says that ít's much better to combine Mytek with a PCI audio card . He recommended RME HDSP 9632 .
Is that a good choice ?
Does it exist any better alernative ?

Looking for new options for my mobile rig. Has anyone had any experience with this?

Cabled PCI Express for Desktops and Laptops

Anyone have direct experience with RME PCI cards. I'm using an M-audio audiophile 192 ($129), and wondering if the RME ($499) will make a noticable difference.

I'd like to upgrade my DAW operating system from WinXP to Windows 7 and take advantage of the increased RAM capability. I would need to upgrade the motherboard and processor. However, I really do not want to, nor do I have the money to replace my 3 PCI interfaces with comparable PCIe interfaces. My experience has been that the most legacy PCI slots available on newer motherboards is 2.

Peripheral Component Interconnect, originally designed by Intel, is an interconnect system for sending data between the CPU and peripherals independently of the processor.

Summed analog 2-bus out of Lavry AD10 into second PC. Need a AES/EBU PCI card.

Any suggestions?

I've been told that ITB converters may be a better choice for high end audio now. It does make sense. What are some of the better PCI converters?
