I stopped at JS Audio in Bethesda and the sales person was very excited to show me the USB DAC from Meridian.  The Explorer is both a DAC and an Amplifier.  Jason demo'd Beck - Lost Cause and Pink Floyd - Money.  Instantly I was convinced what I was hearing was better, but I didn't immediately know why.  (For the record - I was also listening to a pair of Fostex TH900 headphones and at one point we used the L

Lenovo sent me a Recovery Media Kit - so, I decided to reinnstall Windows 7 Pro to see if their installation would resolve an issue I have been having with the SD card reader.
