Hey friends, I have spent now about 30 hours listening with the Magna and have 12 pages of notes to consolidate before sharing impressions.
I know there is a lot of interest for the Immanis (I share it and I am in line for it also). But, the Magna is amazing. Absolutely amazing. I encourage everyone to get a listen, especially if you own the SR1a already.
Here's a small excerpt from my notes:
The Magna is not an “also ran” in the shadow of the Immanis. I find it to be the most versatile and "all rounder" capable headphone I have owned yet, especially as a partner to the SR1a. It may also represent a better choice for listeners with a focus on specific genre that will capitalize on its bass energy, its overall visceral engagement, and what I refer to more than once, the sense of live venue listening.
The Magna is a dynamic as hell, detailed, spacious listen. Punchy bass combines with rich, substantive midrange/vocals, and the hyper detail and speed typical of ribbon drivers. It is the perfect complement to the SR1a, bringing a warmth and weight that the SR1a does not have in the same measure. The Magna is an extremely detailed and technical headphone. It reproduces as much of the source material as any headphone I have heard. And it has fun doing it.
The Magna is not simply 66.6% of an Immanis. It is a unique top of line headphone worthy of consideration in its own right.
