Bi-amp through receiver vs pre out to 2 channel for fronts

I have really nice speaker cable from Canada called Phantom cable. It’s 12ga.

I can explain what I learned about using the subwoofer (for bass management) between the pre amp and amp instead of an integrated amp if you would like.

The Atoll 5 channel amp has two toroidal power supplies and all independent transformers in it, so It is essentially similar to having two two channel amps. The good thing for me is that it will be flexible if I ever expand my upstairs system into a 5.1 (right now it’s a 2.1) and until then I can bi amp which as you said is probably more mental than actually making a difference in sound. I do see your point that maybe I should just get a really nice 2 channel amp for now. I could still get the Atoll 100SE which is a nice 2 channel, but the 5 channel is scaled properly with added components and not much more money. I’m not sure f I would rather have anything over it at this point. 

I know you can’t tell over a generic recording, but you can kind of get the idea of the detail in this one.

The question still remains,  If you have auditioned the amps, which way did it sound best?  Forget manuals etc.., it's all in what the ear says.  I personally always keep my 2 channel system as simple as possible.  Fewer cables and interconnects is best for sooo many reasons.  You seem to feel strongly on going the 5 channel route on your sound though.  I say go for it that's what you want.  

Also please try to keep in mind that cables, like components need to work together in synergy.  Just because you have liked a cable with one system, doesn't mean it's going to work in another. I've found that Audioquest is one of the few cables I've heard (and I've heard many as I audition many systems) that is neutral enough to be used and sound good (because you don't get any sound signature) as I've heard.  Mostly their mid/high to high end ones.  Have never heard a truly balanced cable that's inexpensive, but that's to my ears.   Just get what you want and what your ears have told you to get and then jump off the boards, or you will drive yourself nuts, lol. 

CTSooner, You are probably going to cringe when I tell you that I didn’t audition the Anthem amp, but it was too good of a deal to pass up. The Marantz sounded nice to me, but they all sound nice in the store. Again, I found too good of a deal on a new 7704 to pass up either way. 

I only purchased HT for my downstairs theater system so far. I have been leaning towards Atoll for my music setup, but I am going to hold off on any purchase until I have a chance to really audition at Overture in Wilmington Delaware. I may stick with 5 channel in case I want to run a movie upstairs, or I may just buy a 2 channel and use upstairs strictly for music. 

For now, I ordered 4 custom ICs you can see on my other thread. I ordered Buelund impregnated oil with Cardas RCA connectors.
