When the original SkyFi units were the rage of the day, many of the XM audiophiles took advantage of a modification service being run under MYRADIOSTORE.COM. By adding optical output capability to the SkyFi, subscribers were able to enjoy enhanced XM audio that only a direct digital connection could provide. Here is how it worked.... Essentially you either purchased a SkyFi unit with optical output already installed or sent in your own SkyFi unit for the modification surgery. The modification cost $99. Once the SkyFi2 was introduced last year many of us inquired how we could have these units modified as well. At first, the news was not good. The folks at MYRADIOSTORE.COM had difficulties getting around the extra electronics inside these units to install the optical hardware. I have just received word that modification tests have been successful and now subscribers can have their SkyFi2 upgraded for optical output. In fact, I have been informed that MYRADIOSTORE.COM is offering a limited time discount for anyone wishing to have their SkyFi2 unit upgraded. To take advantage of this discount Please Click Here. Home Theater Forum makes mo profit off of steering you to this site. For that reason you can trust the fact that I am recommending an audio output upgrade that many of you will probably benefit from.
