Dang if I didn't order the DX7 Pro, I would have order the A90. The DX7 Pro is on the way to me though, if I didn't like it, I will return and get the A90
I don't know the DX7, I could be wrong: but I can vouch for the A90.
The one thing I can say with certainty now, magneplanars respond extremely well to amp improvements. And because the Arya is one of the more difficult to drive, it seems to respond even more to quality amplification. I dare to say with the Arya, that the Amp is more important than the DAC.
I tried the Arya on many different amps, the step up in SQ is not subtle: typically you get: more bass/warmth, more Pace/Dynamics, bigger soundstage, more of all the good stuff.
I'm 100% sure there are better amps out there, but for $500, the A90 improved my Arya is such dramatic ways. My SMSL SP200 has an excellent reputation with the Arya's, I can only agree. Still have both amps, its easy to do direct comparisons: but the A90 improvements on the Arya are not subtle at all. My desire for EQin the Arya (boost bass, cut 5K highs) almost completely disappeared.
Read the Soundnews review, I can only confirm his conclusions.
I apologize for being such a A90 shill, but I really hope you can also try the A90 and compare it to the DX7 before your decide. If budget is an constraint, I would add the Topping e30 DAC to the A90.
