TOTL imaging chops/layering. Tons of micro-details. Bass texture and impact second probably only to the Z1R. Wide and 3D staging. AGGRESSIVE, and get fatiguing when cranked up/long-listening sessions. Jays Audio Youtube Channel

A warmer, more coherent MEST with setbacks in resolution and imaging. Precogvision Youtube Channel

Pretty much the same as the Mk1, though with extra sub-bass presence. Crin Youtube Channel

Comment: Bassier Mest v1 with slight cutback in clarity. Even more impressive bass response
Unique Melody MEST mkII reviewed by: Nymz
Great bass and sheer detail, at the cost of wonky treble and not so accurate imaging queues. I find it work the best with eletronic music or modern metal. Still a solid contender to this date at a very good price in the used market.

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
Symphonium Helios SE reviewed by: Precogvision
See Helios but with more mid-treble and mid-bass. Precogvision Youtube Channel
Symphonium Helios SE reviewed by: Nymz
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.
