Any feedback on a MSB Power DAC?

Has anyone heard the MSB in a system? How does it stack up to other DACs in its price range $ 4300?
I own a MSB Platium CD Player II with new digital filter which is more money and I have tested the Power DAC and it comes close in sound but if you can swing the dac III your better off both in sound and portability and upgrades. One other thing I have be told that the power DAC and new ilink can't be beat. I have the ilink for my Player II and love it.
Is the ilink the interface that MSB will install in a player for a direct connection into the DAC?
