anybody know a true dual mono passive preamp?

I'm looking for a good value true dual mono design passive preamp. I'm using a very cheap Channel Island passive preamp connected to an expenssive Gamut D-200 amplifier and I'm very satisfied with the sound. I compared the Channel Island to McCormack TLC-1 and I prefer the CI. I don't believe on overprice product specialy for a passive preamp.
I know there are very good value passive preamp out there like the Channel Island and the FT Audio LW1. pls. share your experience with us. Thanks to everybody.
