Hi Barry.
I do like the sound of this preamp, it seems to get better with use. I know its controversial to say....but I swear its broken in some. Ive had the break in effect with most of my new diy gear, some more than others...
As far as the speaker comparison, I don't think your view is all that much different than mine.
With the 7pi corner horns, the kick drum DOES sound more realistic than the 4 pi's.
To my ears in my room, the 4pi's with flanking subs are not way off...second closest to a live sound or "band in the room" to the 7pi's.
I'm guessing the corner horns have the 4pi's beat in the 200-2000 Hz range.
Have you ever heard the difference between a kick drum low passed at 150-200 Hz. vs. 1000-1200Hz?
I'll tell you that the degree of realism and PUNCH from the 1000Hz sample is massive compared to the other.
To my ears, mid range clarity and accuracy have a huge impact on the realism of a recorded event, it sounds more "live".
I don't doubt the mid horn is better at that.
As far as the subs, my room may have a lot to do with it.
The entire ceiling is an 8" thick x 14.5' wide x 28' long bass trap. Ive had the subs distant and it makes absolutely no difference.
Walking around the room with test tones (or music), there are no discernible nulls or modes that can be heard. The room is generally flat no matter where the subs are located.
I put them front and center for practical reasons,
and for the use of low frequency extension alone. They just happen to be flanking the corner horns (towards the inside not outside) Also they are in an alcove so the front baffles are flush with the front wall.
Ill try to post a pic.
When I had the system upstairs (exact same dimensions but no bass trapping) it was a totally different story, and the distant (and flanking) subs made all the difference. Really evened out the bass response in the room.
To my ears the flanking subs still helped the most. But then the distant subs helped really even it out the rest of the way.

Your room sound like it's great. In the 4 rooms (in 4 different houses) we've tried multiple/flanking subs it's improved the sound each time. I'd begun to believe it would work in every room. Obviously that's wrong.
Maybe your room is why the front firing bass bins and the 7 pi doghouses sound similar. It's my only guess, and it's only a guess.
Nice equipment rack. ANK amp on top, a couple of Oddwatt monoblocks to the side, your new VTA preamp in the middle and two crowns on the bottom. The only one that's hard to figure out is the box on top of the Crowns. And no idea what drivers are in the subs.
A lot of audio gear breaks in, some more than others. And it's not just your ears getting used to it as I've listened to fresh gear, left it running and wandered back after several days to hear the shift.
Capacitors are the weirdest of the lot. Some sound about as good as they ever will in less than an hour, some require 100 or more hours to settle, and some go back and forth between good and dreadful for days at a time. The ones that shift around are the biggest pain because you're wondering the whole time if you made a big mistake getting that piece of gear. Even more reason to set it up, turn it on, then walk away for 4 or 5 days. Hope your new preamp continues to excel and sound better.
