Penon Impact Reviews
Penon Impact reviewed by: Nymz
Limp bass, but good mid-range and treble tuning. Techs felt underwhelming for its price, with extremely blunted transients.

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: Jays Audio
U-shaped/Slight V/W Shaped. Energetic treble. Great tech. Fun signature. Jays Audio Youtube Channel

Suffers from BA bass, and super Zingie Treble. Jaytiss Youtube Channel

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.
