Upgrading Aerial Acoustics Model 7T

Hi @indranilsen,
 I heard the Atria's in a very nice room and they were driven by an Innuos streamer, DCS Bartok DAC and the smaller Gryphon integrated amp. I was actually surprised by how similar that system sounded to mine in terms of dynamics. I didn't sense any more "meat" with the Atria's but the sound stage was decidedly different. The Atria's presentation was very well defined but narrow while the 7Ts at home throw a slightly less etched but much wider image; depth was excellent and about the same. Again, with so many variables, (different room, different electronics) I'm not sure how useful this info is for you and yes, I'd think a home demo is a must given the Atria's are 2.5x the cost of the Aerials.
The 7Ts sound great when driven by the Pass but it is not significantly different than the Parasound A21 which I have heard driving the 7Ts many times. As a point of interest, the biggest game-changer for me was when I added the Backert preamp; putting that in my system was like getting hit with a bolt of lightening! Then, when I upgraded from the Bluesound internal DAC to the Benchmark was another significant and immediately noticeable step up.
In regards to my setup, the distance between the back of the speaker and front wall is about ~33 inches, the front of the speaker is ~4' from the front wall. When you ask if I am getting "full depth" I assume you are asking if I am satisfied with the bass response? And I would say yes, based on what I hear the 7Ts produce from well recorded tracks I am. 
Good luck.

@Chilehed- Thanks for your detailed response. In fact I listened to Atria-II with DCS Rossini Rossini DAC driven by Gryphon integrated amplifier in Goodwins High End audio showroom in Waltham-MA. Yes I will audition Atria -II in my room before making the final decision. 
On the speaker positioning topic and by depth I mean, are you getting the image way back on the wall behind the speakers being completely detached from them. The only way I get that in my room is leaving around 5' distance measured from the front of the speakers. But you are close and it should be good.

I also heard the Atria's at Goodwins but with a different DAC. The image in that room is compressed compared to what I hear at home. They had the speakers toed in quite a bit so was thinking that could have accounted for it? While there I was more interested in comparing the Innuous Zenith streamer to the Bluesound Vault.
If I listen to a reasonable recording in my room at home, my speakers disappear completely with very good image definition, depth and width. Is your room treated? I've done the basics but I have more work to do in that department. 

Please let me know if you upgrade and plan on selling your 7T’s. You can email me at jwincville at gmail if you want a quicker response.

Thanks!

What aspects would you most like to improve upon over the 7Ts?
