A-Ambient Acoustics AM7 Scorings
Average Technical & Tuning Grades
Average Tunign Grade
D+- Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.
Average Technical Grade
D+- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Average Tunign Grade
A+- Well-executed tonal character. No major flaws with good technical control. Smooth presentation works with multiple genres.
Average Technical Grade
A+- Very competent with articulate presentation. Well-defined layers and precise imaging. Soundstage is immersive and handles dynamics well.
Ambient Acoustics AM7 Reviews
Unreliable switches, mediocre technical ability and the tone is slightly off. Crin Youtube Channel
Symphonium Crimson Reviews
U-shaped/Slight V/W Shaped. Energetic treble. Great tech. Fun signature. Jays Audio Youtube Channel
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.
The bassier Helios with no sacrifices to clarity
Colored tonality done correctly with incredible bass and dynamics. Upper-treble can be slightly too zingy depending on source. Precogvision Youtube Channel
Excellent bass, dynamics, and resolution. Very large soundstage with great imaging. Mid/upper-treble may be too elevated for some.
Suffers from BA bass, and super Zingie Treble. Jaytiss Youtube Channel
