Apollo Twin X Mod

Apollo Twin X Mod

From: $399.00

All the elements of the new Apollo Twin X mod combine to greatly enrich the sound of both tracking and playback. The soundstage is presented with additional depth and instrument separation that can best be described as a 3 dimensional quality. Frequency response gets a major boost in linearity, resulting in improved perception of the frequency distribution in a mix. Highs become sweet and smooth, mids sound pleasantly natural and bass articulation shines through.

Mod Rating

We often get asked our opinion on how one interface compares to another, so we’ve decided to create a rating system based on subjective A/B listening tests. The scale is from 1-10, with “1” being unimpressive audio quality and “10” being true audio excellence. This is an exponential scale, so going from “1” to “2” isn’t nearly as big of a jump as going from “9” to “10”.
Please keep in mind, we only modify an interface if we can make a significant improvement to the sound. All of our ratings are ultimately a matter of opinion. To view how we rate all of our mods, click here.
