Tekton Double Impacts

Hello all you audiophiles, I'm new on this forum but have been following it for some time now. I just ordered a pair of DI's with the upgrades. I consider myself as a Audiophile wana be as I don't have any real high end electronics but I do have high end speakers which I kept and still have which are Kef 103.2s (2pair) Kef 105.2s (1 pair) Pasetechnology 10.5s (I sold). I auditioned the GE Tritons but was not completely satisfied. Then I started reading and reading and reading all I could about these DIs, Well I'm sold after hearing all the positive feed back and ignored the negative. I even spoke to Eric briefly. Now onto my electronics, I have a Bryston 4bsst, a Acdcom 5ch 150w into 5ch, and Adcom 860 preamp. I also have a Mac 4100 receiver that's 75w into 8ohms and 100w into 4 ohms and I also have an 80s Tandburg 45w receiver.

I have 2 questions to whoever can steer me in the right direction since I cant upgrade any of my electronics for a while.

Which of my electronics do you think would work best with the DIs with what I have ? I was also thinking about running my Bryston through my Macs preamp Then trying just my recievers hooked up to the Did, any suggestions will help greatly. I would like to go tubes in the future.

Now my 2nd question, which is a beauty, I live in a large A-frame house, my listening space is my living room which is almost but not quite a perfect triangle. Its 24'L x 24'W x 22'H. I have no choice but to use the angled wall to place the speakers on because one end wall has a double door an a large window on it, the other wall is open into the dining room and kitchen. That leaves me only with the angled walls to use for my speakers,

Now when I place the DIs against this angled wall  being 54"s tall they will be about 3"s away at the  top of the speaker and about 3' away at the bottom. That sort of tells you the angle of the wall, But they will be 3 1/2 to 4ft away from the side wall and the other will be opened into the dining room.

So the question is what do you think of the placement vs reflections, I hope I don't sound ignorant here but like I said I'm a wana be audiophile.

Thank you for any feedback.

Just a little update on my DIs, I have about 40hrs listening now and I think I'm done on placement and ended up with 9' apart 41/2' from the side wall, 3 1/2' from the wall behind and 10' from listening position. I get a soundstage about 4'-5' past each speaker and about 4' above. Perfect!

So my 30yo daughter stops by and sees them and says boy those are big, I say yeah and she says what speakers are you buying next? I tell her this is it for mains, I'm 61yo and told her the quest over. I'm extremely happy with these and ask her ya wanna listen to them she says ah yea so I told her to sit in the sweet spot and threw on some Alan Parsons for her. Now my daughter knows about as much about listening to music as I dont know what to tell you. So I stood behind her and watched her head look to the left and right past each speaker and she says WOW those are crystal clear and they sound like 3D she says SWEET! Dad, and went back to looking at her cell phone. Any ways I'll be back after more hours go through them. So far I have to figure out the adjectives to describe these when I' done.

Does any one know if the extra resistor comes with the upgraded crossover option?

Thanks
