Audiomeca vs. Audio Aero


Has anyone compared the Audio Aero Capitole (which I know) to the Audiomeca Mephisto 2x (which I have not heard) ? I'd like to know whether the Audiomeca has the same presence and energy on attacks as the Capitole (after all they do share some innards...).

Thanks !

I had the chance to audition both the Aero and Mephisto 11.X. You are correct they do share the same chips(dac). I found both of them exceptional sounding one box players. A liquid midrange, extended highs and solid bass. I researched threads here on Audiogon and elsewhere and found serious questions on the dependability of the Aero( I understand that may have been corrected). In the end I decided on the Audiomecca and have been quite pleased with it. It did have a rather long burn in time though.
How long of a burn-in period ? I also heard the Audiomeca may be a tad warmer and less detailed... Is that correct ?

Thanks
It took about 200 hours in my system for the Audiomecca to sound its best. As far as warmer or more detailed I found them very similiar but in my system, the Audiomecca edged the Aero in detail, more analog if you will. I should say that the differences were not night and day and probably somewhat system dependent. I went with the Audiomecca on sound and built quality but I believe I could live with either one very easily.
I have heard both the Audiomeca and the Audio Aero, but not their newest versions, although it is my understanding that neither the Mephisto IIx nor the Capitole Mk II break any new ground in sound, although they may sound slightly different from the earlier versions. In my listening, the Audiomeca was better. Exceptional detail, holographic midrange, tremendous air around instruments, excellent mid and high frequency presentation. No brightness or harshness, but exceptional detail with liquid midrange, clarity and transparence throughout. The Capitole sounded like a good player to me, no obvious flaws, but in the couple of times that I heard it, it didn't strike me with the exceptional qualities which I heard in the Audiomeca. The Audiomeca unfortunately doesn't have killer dynamics or killer deep bass. In my opinion, these are the only things it lacks. The Capitole has never tripped my trigger, perhaps due to less than excellent recordings or room conditions or associated equipment.
