Average Technical & Tuning Grades
Average Tunign Grade
C-- Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.
Average Technical Grade
E+- Noticeably blurred or congested. Struggles with basic instrument separation; details are lost in simple tracks. Feels "flat" and one-dimensional.

Symphonium Crimson Reviews
Symphonium Crimson reviewed by: Jays Audio
U-shaped/Slight V/W Shaped. Energetic treble. Great tech. Fun signature. Jays Audio Youtube Channel
Symphonium Crimson reviewed by: Jaytiss
Suffers from BA bass, and super Zingie Treble. Jaytiss Youtube Channel
Symphonium Crimson reviewed by: Precogvision
Colored tonality done correctly with incredible bass and dynamics. Upper-treble can be slightly too zingy depending on source. Precogvision Youtube Channel
Symphonium Crimson reviewed by: Smirk Audio
Excellent bass, dynamics, and resolution. Very large soundstage with great imaging. Mid/upper-treble may be too elevated for some.
Symphonium Crimson reviewed by: Shuwa-T
Strengths: The bassier Helios with no sacrifices to clarity.
Symphonium Crimson reviewed by: Nymz
Great bass, holographic stage and top of the shelf dynamics. Probably my favourite rendition of a W-shaped tuning to this date. Treble might be spicy for some, but using Divinus Velvets (stock black) seem to help a lot.
