This is THE step-by-step guide to setting up and fine-tuning your audio or home theatre system. Roger Skoff of XLO Electric (innovators in the field of cables and interconnects) and "Prof." Keith O. Johnson (audio guru and co-inventor of HDCD) lead you through a quick and easy system set-up. Included are tracks dealing with Balance, Wiring and Polarity, Speaker Placement, Soundstaging, Imaging and Depth, Absolute Phase, Component Demagnetization and Burn-In, PLUS a varied selection of RR jazz and classics to show off your fully-tweaked system! (Music includes: "Stormy Weather"; "Shiny Stockings"; GOULD: Derivations; JANACEK: Sinfonietta (excerpts); BIEBL: Ave Maria; WEINBERGER: Polka and Fugue)

Just want to share this "amazing" CD.
It's useful and helpful to set up, check and test the sound system.
Tracks 7 & 8 really works and it works every time.
I have this disc for the pass 7 years with my previous car and I just remembered to use it for my 3IS yesterday.
And, it sharpens the treble & details, improves the soundstage and tightened the bass.
All I did was to repeat track 7 & 8 three times to "demagnetize" the sound system and electronics.
I would really recommend to buy/download/beg/steal/borrow this CD that will last u for the years to come

 

nice. DO you have a aftermarket stereo in your 3IS?

 

Mine is the stock standard premium system (non ML)
