Average Technical & Tuning Grades
Average Tunign Grade
A-- Expect an inviting tonal blend that adapts well to genres while staying largely composed. It strikes a nice blend of warmth and clarity.
Average Technical Grade
A-- It manages detail and layering well enough, even if the stage feels only moderately sized. You get a clear sense of left and right, if not depth.

Average Technical Grade
A-- You get a controlled, composed performance, marrying decent clarity with a still-modest sense of space. A safe technical performer for the price bracket.
