Supra MD-06 review

Vocal clarity increases and is more transparent, but the sound is leaner

Our Verdict

It adds clarity, but some might not like the leaner sound


  • Well built, tightens the sound and gives impact


  • Some might not like the leaner sound and loss of depth

With its sturdy aluminium build, and rugged no-nonsense appearance, the Supra LoRad MD06-BS/SP mains filter looks quite formidable on our testing rig. In terms of build quality this mains block seems more than decent, and for wall-mounting, comes drilled with six holes, although these could prove small and fiddly for some.

We gave the sturdy Supra LoRad MD06-BS/SP Otis Redding's emotive and rich-sounding A Change Is Gonna Come to handle, and the Supra's effect on the sound became noticeable.Vocal clarity increased and became more transparent, but the sound also became leaner, losing some of the depth and the characteristic punchiness of a good soul recording. Despite the advantages, it doesn't offer enough improvement to justify a higher rating.
