If you are a lover of bass, this is a good option. Does not sacrify the rest of the sound signatureSuper* Review original ranking

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
