Luckily, im just bored in the office, so I can reply right away ;-)
Well. That guy looks like doing nice quality. Id go there.
Knowing your profile a bit, Im not surprised you don't want a digital delay on your mains.
For me theres no non-digital life anymore, I desire perfect transient, and fullrange sucks.
Knowing your profile I also see sensitivity to timealignment. And human sensitivity increases in the lows, especially below 200 cycles. So careful.
Id recommend to hear it first, again, as a refresher, with focus on some characteristics, which you will most likely not overcome completely.
Youll definitely get the unique benefits, which I can skip here, its amazing and not subtle and only Khorn can do it.
But with the delay, youll have 2 main issues:
- drums separation. Listen to drums. Youll notice that the "Tommmm" sound will get a slight "tock-flummmm". on microscopic scale, you really need A-B comparison to clearly identify.
it will also make the bass more bouncy rolling soft. Which is quiet nice 
but yes, not as dry hard as the recording was taken.
- depth of field / stage will extend further away. On some recordings it will unveil first time difference between the instrument position. On others artificially overexaggerate a 2 meter difference into 10. which is cool, but also not so realistic
All in all, the benefits are big, the downsides pleasant.
But you should know what youre heading to.
Many do mistake to put them approx. cornerish with gaps behind, no lid, midbass becomes horrible!
They also abuse it as a sub with force to 20Hz (with >24dB boost), doesn't get nice on hi level as you modulate the prechamber size with xcursion and distort the fundamentals.
If... you stack 2 (cut xcursion half), add a phaseplug (reduce prechamber volume and such shift the modulating frequency up out of the range), cross bit lower (200?)... you can reduce that a lot.
Phase plug easiest is get a wooden bowl that fits into the cones, cut them in 3 slices, take the gap of 10 centimeter in the center out, close the middle left and right with a halfmoon board, and the plug is done.
Next would be that the subs for the bottom end need to have the same delay then to fit the K's. Meaning moving them further away... (some roof corner end of the room?).
Lot of thoughts, but listen. Its worth driving 100 miles.
cheers

PS: for me the superior rock solid midbass and fundamentals are the killer feature. no matter which volume, its just layed back unconditional stability that makes goosbump like no other. It also, despite the delay effect of soft rolling impulses, makes it still .... how to say, its ironic: fast dry ? Its contradictionary as the delay should cause the opposite, but the clearity somehow compensates. Overcompensates. And don't neglect how little electricity you need. Especially using DSET. I just ran mine weeks ago for fun-test on a non-D SE-pentode with 1 single watt. Still easily rocking the house!Rerurn to Romy the Cat's Site
