How important is upgraded power cords for FM tuner

Bob Crump Assylum cord will do the trick.You will spend 5/10 times more to = it.

Best to listen for yourself and find out.

As stated already, you will have to listen and see what makes a difference. With my MD102 I found that the cord does make a difference. Also found that the "balanced" outs performed better. The greatest improvement was connecting it to a balanced output power conditioner. Of course a directional antenna above the roof line will do wonders for performance too. Good luck!

Used a Virtual Dynamics Audition PC on my Magnum Dynalab Etude and the results were staggering! I would definitely look into the PC's. I've looked around for a while and decided to use Rick's PC's at Virtual Dynamics.
