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
B-- Competent but unremarkable. Decent detail retrieval in quieter tracks, though busy sections challenge cohesion. Imaging is average, lacking depth.

An otherwise capable hybrid caught out by nasally and odd midrange. Crin Youtube Channel

Best Treble around it's price. Super airy but still smooth. Bass-scoop isn't as bad as I thought, but those who want mid-bass - avoid it. Jays Audio Youtube Channel

See Helios but with more mid-treble and mid-bass. Precogvision Youtube Channel

8.1
Reviewer Score
Limited to 50 units. A huge improvement fit wise versus the original. Great TOTL all-rounder. Great sub, upper mids and treble. Mid-bass is an improvement but still not boosted. Great technical chops while fixing the sense of plasticness the original had.
