Music Preferences and Comments:
Music Used (Genre/Selections): Classical
Mostly symphonic and piano
System Goals/Comments: I suppose it is a modest system by Asylum standards, but to me it is both expensive and wonderfully musical
System Strengths: I love it
System Weaknesses: Possibly speaker placement. Probably the cables. But none really that I can hear.
Video/HT System: None
Other Interests/Hobbies/Occupation: Amateur pianist, formerly piano student for many years.
