It is good everyone has Scheherazade Reiner. Imo It is a great piece of music to demonstrate how good the system is and compare. The music has pretty much all elements to see if a system can present. It has the flow, the dynamic range, the rise and fall, the surge from quiet to loud, the delicacy, the haunting hollowness of woodwinds, the movement from one instrument from one place to another, the instrument great timbre and differentiation, the layering, the portray of different location of different group of instruments, the ambient air of venue, the build up, the excitement....basically everything. A good listening "experience" of this piece can make you stand on your feet with joy and blood rushing within. When comparing systems with Scheherazade I like to pay attention from around 3:00 (in this case) and on for 3 minute and that should be enough.
Yes this system lacks transparency if he can identify what causes that then he will open the door to really experience the Reiner's Scheherazade. Hope he doesn't need half a million $ of cables to get that though.
