A: Stay away from Audiogon; a bastion of audio pseudoscience woo. B: Corns and Scalas can be driven perfectly fine with no discernable difference between any well made SS or tube amp that is rock solid 4 ohm stable. I'm sure that MC225 will run them at even blistering loud volumes. IMHO, tubes are audio jewelry. Get a good SS. With the music you like, I'd toss in a sub with either the Corns or LaScalas.

Love them. The best sweet spot is just behind, like 6" behind my head. That extreme toe in is second.

How about make some false corners so that the long wall works with the Khorns?

The placement, as you described, is the best for stereo imaging. The Reference I manual suggested this exact placement IIRC. Also which is nearly just as good, is keeping the speakers at the same place as above, but swinging them at a 45 deg angle where they intersect about 2-3' in front of you. You do lose some depth of sound stage, but sitting off to the side is easier. I'm just curious as to what is the magic potion in Klipschorns that they can project sound out of their corners. I don't doubt there's an answer.

My 5 Best, as I don't feel it's appropriate to rank speakers sense tastes, rooms are different Klipschorn/LaScala: This is room dependent. The perfect room demands the Klipschorn, but as you get away from that the LaScala wins Vandersteen Quatro: Very smooth, warm sound. Vandy makes more expensive models but I can't discern a benefit Martin Logan: Any Electro Stat in the ESL reserve series which sounds the best to you for the money. Honestly, I can't tell a difference between them so I'd go with the cheapest JBL: M2 Studio Monitor Philharmonic Audio: Philharmonic 3; absolutely the best deal on the planet.

None, actually Yamaha makes probably the best integrates for the dollar IMO. Get the best you can afford and yade yade. My only caveat is that to get that last little push from any of the Reference II speakers is to have a separates, especially the RF 7 IIs. I have an Emo XPA2 for my RF 62s for instance.

These are an absolute steal.

See edit, just meant run of the mill integrated or receivers. No slight to ANY Yamaha integrate.

http://www.libinst.com/PublicArticles/Setup of WG Speakers.pdf I have RF 62 IIs, read this, thank me later.

The difficulty with those speakers is driving the lower end, 80-250 hz, where it's a 3 Ohm speaker. I'd suggest going with separates and get the most solid state you can find. Like a 2 channel Emo. In any case, all advantages here are at spirited to loud volumes, mid and low volumes likely won't see the benefit from any average integrate or AVR

But, like I was saying, my RF 62 II towers sound like crap in the corners, imaging and sound stage gets lost. I assume that the Khorns wouldn't, but why?

You might want to think about a sub. I got two sealed PSA XS15SE and they are stunning for music. That model is replaced by the S15, or S1500 for down or front firing options.

http://www.libinst.com/PublicArticles/Setup of WG Speakers.pdf Set your towers up at a 45 deg angle and place them out where they intersect 3-4 feet in front of you. This link gives you the science behind it. Make sure you're not using YAPO or anything like that, at least at first.

Assuming you have an 18' wall, do you have to sit 9' away (where the Khorns intersect) from the wall for best results, or can you sit further back? Also, I have experimented with my Klipsch RF-62 II in the corners and it basically sucks. PWK suggested in a 1960s Dope from Hope that all speakers should be corner loaded, was he saying that based off of what was out at the time? I hear a speaker way over to the right, and one way to the left, and phantom center. I'm guessing that the Klipschorn has some sort of way of overcoming this, how? Can you get away with having an entertainment center between the two Khorns, or is this a no-no?
