Everything is sounding very good. I am pleased with all the changes and the benefits. One thing I realized is that I have never tried the phono preamp built into the Onkyo A9555. It is only for high output cartridges so I thought of removing the Benz MC Gold and reinstalling the Grado and trying the built in phono. The Cambridge Audio 640P sounds good but I thought it would not hurt to try the Onkyo. Any ideas or opinions?
