Thank you for the honest and truly insightful review, shotgunshane. It's a shame, really, since I'm quite fond of my MG7's, and had high hopes for their custom flagship. On the other hand, my wallet thanks you.

Thanks for the comments. Yes it was very disappointing, not to mention depressing to think of wasting so much money. On the bright side, I'll have an Aurisonics AS-2 soon. I've heard the prototype and it was very good!

did you burn them in? i had the same problam with my atrios being very harsh and full of sibliance after i think a 50 hour burn in it litrialy dissapired and was shocked on on good they sounded...

Of course, I have hundreds of hours on them. FWIW you can read more comments at the review's original location: http://www.head-fi.org/t/596839/review-unique-melody-merlin-future-sonics-mg6pro#post_8160471
I hear the same uneveness in the upper mid of the Atrio (mg7 driver), however in the Atrio it is at a very tolerable level. Also the Atrio is not as colored in FR as the mg6pro.

intersting thx for the review i fell like i am not makeing a blind purchase i fell i really need to demo these to see if i like them if not

No problem, thanks for the comments. I'd recommend listening to a demo first but I don't think Future Sonics makes demos. Also keep in mind that Future Sonics doesn't allow refunds and reshelling is impossible, due to the glue destroying the driver upon removal. Future Sonics confirmed this and told me they always replace the driver for rebuilds during warranty period. The typical reshellers also wouldn't touch when I inquired b/c I wanted to be able to sell them.

As another owner of the FS MG6Pro, I have a suspicion that the 3k-4k discrepancy that you mention (which I hear as a kind of 'honking' sound, on my pair) may be due to a resonant frequency of the air chamber within the CIEM shell, within which the dynamic driver is glued, in 'free-space'.

As I posted, in your thread, Shane (some years ago), I consider it absurd of Futuresonics to have made no attempt to account for the resonant frequency of the air chamber within the CIEM shell, AND to have (seemingly) made no attempt to make the chamber dimensions and volume identical from one pair of MG6 Pros to the next.
