What Impedence Do I Need?

I am thinking about using MIT cables between my spectral 90 amp and spectral 20 preamp. Which impedence do I need?
The website will tell you. www.mitcables.com
Mit makes a special line strictly for Spectral as you may already know. I recommend you contact *Joe Abrams* at this web site. (That's his user name). Not only will he answer all your questions about MIT products. He could probably sell you the exact cable you are looking for at 1/2 off or better.
First you need to know the input impedance of your amp. Check the manual then contact membername = joeabrams for excellent advice & great pricing on your MIT's.
Yes, definitely, conctact Joe! There's none better in any respect you'd like!
