K-horn won't fit, any other corner speakers recommended for a big room?

@rooze I'm with you on the dipole.  I think that any dipoles will require too much space behind and beside them for me to seriously consider trying them out.  Although I do believe that you don't know until you try.  

I have been looking at Ohm for quite some time and I do believe that the Walsh 5000 could be an excellent attempt to make it work.  I may have to take advantage of the very generous at home trial period that Ohm offers to see if these would work.  At full retail pricing, I'd have to start selling off a lot of equipment that I may not be ready to part with just yet.

I have been speaking with John Huff of Huff Loudspeakers about some of his Omni's that he has leftover from his days in the industry.  He seems to feel confident that his Huff Three would do well in a corner such as mine and is willing to make a deal.  There is much debate about omni's out there and the lovers and haters both make great points.  With my limited knowledge, I think that dipoles would be tough for me to pull off and omni's could be even harder to get right.  Any thoughts on omni's for a very wide separation and corner placement in a big room?

@tsushima1  yes, budget would be helpful.  I’d like to stay under $5k if at all possible.  
 

@audiokinesis   I have been looking at the 7 Pi for awhile and have considered it as my last alternative.  I have built a few cabinets as well as speakers in my day, so the option of building a pair is real, but with this prior experience I also know how much time that takes to get woodworking to my standards.  Your first hand experience is the first that I have read outside of the Pi website so that is very encouraging.  To be honest, as I have followed Agon for several years now and have read many many comments and opinions of yours in particular, I take that experience and commentary as the gospel truth.  No BS at all.  The same goes for many of the responses that have been shared on this thread.  It is an honor to get opinions and help from those that I hold on high regard.  Thank you.  

@mijostyn , It's funny to read your comments and advice because you are dead on correct and that is exactly what I found to be true.  Listening in that room turned out to be for background music and replacing the VSA VR3's with a pair of Canton Karat M80dc pulled out of the corners and some precise toe in did the trick.  I think the MTM setup and the small baffle helped to get the dispersion wide enough and far enough to get the soundstage closer to what I was looking for in that room.  I recently added a pair of passive subs to the room to help fill in for low level background listening and this helped a lot.  

I am currently building a new listening room in the basement for my critical listening system.  I have a pair of Acoustic Zen Adagio's on deck for that room.  I am also looking at a Bob Carver VTA20s tube amp to power them, used of course.  I am not finding many customers with reviews of this amp.  I'm not sure if it's because it was a budget friendly tube design or because it wasn't produced for very long or because of the Emotiva connection.  Anyone have much experience with this amp?  I'm looking to get into tubes and thought this may be a good entry level starter, but the lack of users has me concerned.
