WOW, your new amps are awesome! I don't know how you connect your BDP to the M1 DAC, but if you're using the USB input I have a suggestion for you. Check out my comments on the
UpTone Audio USB REGEN. For only $175 it provides a
huge upgrade in performance of the M1 DAC.
You can read much more about it at the UpTone Audio site as well as on some other forums that they link to.
