hmmm 8 pres... you might have better luck posting n the computer forum. Right now i would say check out the presonus firepod, aardvark q10 (have to ind it on ebay or something cause the company is out of business). What kind of quality do you need in those pres? another option would be to get something like the echo layla and get an ADAT 8-pre unit for such as the behringer unit.
