Wow! Effing wow! Those were the first words my family heard upon just a few notes and chords as I started with a concert grand, and gradually drew up some strings, pads and other sonic elements into a familiar layered mix. A few more bars of soft and firm temperament and a shook of my head for a moment like that of a neckless weeble-wobble: "Wow", I continued to mutter as my daughter looked at me puzzled; these unknown facial expressions of surprise as compared to my otherwise normal emotionless, stoic stature.My pianos instantly sound and felt like I was in a concert hall; the stereo spread, the sonic presence. My gosh. I was really deprived with my old d/a. Strings brilliance, brass bold and punchy. Acoustic guitars came out with such live-mic realism. Again, the sonic spectrum is just amazing. Love the fiber i/o. They are my to and fro integrating the desktop system and mobile rack.

Musical Background:
