Musical Fidelity Tuner and Other Qs such as DVD

Friends,

This is not strictly an Amps/Preamps question, but it was either this or the "Misc" category. It's a multi-part question, and some questions are a bit naive, so please indulge me:

BACKGROUND: I have a Musical Fidelity X-ray, X-10 V3, and X-150 driving JM labs Chorus speakers; MF components fed by Shunyata Hydra-4 plus 20A Shunyata Copperhead. This is the type of system one is constrained to in an apartment in New York City (unless you earn a gazillion dollars a year, which I don't!). Sound is good, warm and wide, but a bit bass-heavy and mid-range mushy; I am changing interconnects from $100 synergistic alphas to Nordstrom Red Dawn. Anyway, here's the Qs:

QUESTIONS:

1. Does the MF X-PSU confer any additional advantage in driving the X-10 V3 over the power supply (fed, in my case, by the Shunyata) that which comes with the X-10? I have no solid info on what the X-PSU is or does.

2. Does anyone know if MF is going to produce a tuner to complement the current X series? I would really like a decent FM tuner, but don't know where to start. MF remote control is "tuner-ready", but where's the tuner?

3. Ultimately, would also like to run audio from a DVD player (for movies) through the X-150. Here's where we drift further from Qs about MF. Anyone have recommendations for DVD players in the $300-500 range? Looking for something to feed a good quality 40-50 inch HDTV monitor (e.g., Aquos) through HDMI. Zero experience with flat screen HDTVs, and technology/prices seem to change daily. Any and all tips welcome. Thanks :)

Thank you in advance,

Keith
