FWIW, I ordered an ATI 3303 today.
Will post my impressions when I've had time to listen.

For now my amp history:
1972 MacIntosh MA-7100? 1st Integrated
1980 Rappaport AMP-1 100 W pure class A
1992 Levinson pre & power amp(ML-2?)
2003 BAT VK6200(3ch)(still have)
2006 Anthem A5(still have)
2012 Emotiva XPA-1L monos x 3 (still have)
2019 Emotiva XPA-1 Gen2 (still have)
2202 ATI 3303.

More later
I love ATI. Can't wait to hear your thoughts!

I can't wait to hear my thoughts either.
Will be a bit though.
Rest assured I will. Won't vanish as most do

So, I've had my 4007 for a couple of weeks now, but I only have played it for about 5 hours.

I had 2 dedicated 20-amp lines run for it and my ATI 1505.
I don't know what to think at this point. I definitely have to turn the volume up to get it to "wake up" so to speak. I recalibrated everything with an SPL meter. It is softer in the highs as well. Which is kind of a positive and a negative. I use a song that I am very familiar with for all my listening, and I am not hearing some of the detail I hear with the 1505. It does seem that the bass has more authority, and the soundstage is huge like it was with the 1505.
The treble is just a bit softer. I have always felt that the 1505 was almost on the bright side but missing some detail with the 4007 doesn't make me happy.

I am speaker shopping also, and it seems like more and more speakers are err-ing on the brighter side and so maybe it will open up more options for me with it being more laid back?

And while I don't believe in break-in for electronics, I wonder if some will happen as I get more hours on it?

Just as a general statement, anyone can say the same thing about any given amp on any given day.

And I would think that if you believe in speakers break-in, then the same applies to amps as well. So definitely give it a few more days of listening and see if it breaks-in.
