System Goals/Comments: This system sounds quite good and is just about perfect for the size room it is in.
System Strengths: 1) sounds very good, especially realistic on vocal, folk, and jazz music

2) Price. The complete system was around $3000.
System Weaknesses: 1) could be more convincing on full scale classical music

2) small speakers limit maximum volume and impact.

3) imaging isn't the best--mostly due to speaker placement and seating position, I think.

4) Old cheap turntable. Is next component to be upgraded.
Video/HT System: None
