A V-shaped version of the NT6. The change in tuning kills the technical ability slightly

Hidition's take on a V-shaped signature and one executed pretty well at that. Slightly too much lower-treble begets drier sound.

Better low-end texture and overall more engaging than MK2, but lacks the mid-range/vocal magic, so depending on your preference either is great. Still TOTL tech like MK2. Great all-rounder.

I prefer the Monarch MK II for its tonality, vocals, and timbre, but I get why some prefer the MK III. More bass, treble, and detail than the Monarch MK II. The vocal magic of the Monarch MK II is gone.

Elevated, well-textured mid-bass. Pleasant mids. Elevated upper-treble may be pesky to some.

If this is what 'fun' sounds like, I ain't about it.

Recessed mids and odd timbre.
