Tan,
Nice job!

Glad to her you like what the Felix did for your preamp. I finally got home and had a chance to finish building my Felix for my SB3. I agree with everone, It's the best it's ever sounded.
I'm now thinking of placing order for parts to assemble a couple more. I just need to come up with an enclosure to house multiple Felix's. I have a Korato tube preamp, and a Paradisia Dac that might benefit. Have you had a chance to try the Felix with your Renaissance II?
