What should I choose??

How are your room acoustics? 
“Please, I don't need to be told to buy amps or speakers other then the ones I am asking about as I am a big fan of my system.”

Since you like what you have, I would recommend going over your room acoustics one more time, listen and then proceed from there.  By evaluating your acoustics in the room to ensure that you are extracting all of what your total system has to offer, you may be surprised at the improvement in sound. My room is custom built but to my exact specs for sound abatement and acoustical dampening. The best my system has ever sounded and the sound is just amazing. BTW, had a pair of 4BSSTs years ago and they drove the N800s very well but went to tube amplification later on. 

 Please, I don't need to be told to buy amps or speakers other then the ones I am asking about as I am a big fan of my system.

In that case then you should not be buying amps or speakers at all, since either one is bound to change the system you like so much. What you want instead is something that will let you keep everything you like about your system, only make it better- same imaging only better, same detail only better, same dynamics only better, etc etc. Also you want something easy to try and send back if it doesn't work out. Not something it will be a hassle to send back because of all the work and expense of packaging and shipping it back.

What you want then is Synergistic Research HFT for your speakers and room, and ECT for your electronics. Reviews are all over the site, I have them, added a little at a time, and they really work.  https://systems.audiogon.com/systems/8367  HFT are visible on the speakers and walls, and if you look real close will see ECT on a few components. They're on a lot more just not clear in the pictures.

You're probably wondering how much difference something so tiny can possibly make? Well at least as much difference as a $2500 Koetsu cartridge, $3500 Herron phono stage, but not quite as much as a $4k SR Euphoria interconnect. So somewhere in there. A lot of improvement. 

They come with a satisfaction guarantee and can be shipped back in the same envelope they came in for next to nothing. What the heck do you have to lose?

...and don't forget the lava lamps.....a pair, one L, other R, sharing the same AC power source as the mono amps....

That way, the wax responds to the amperage 'draw'.....;)

(BTW....This is a tease.  No implied performance improvement will be rendered by this addition.  Your results may vary.  However, if this mod appeals, we're offering a Great Deal on them!  {Bitcoin Not Accepted}...)

....love the lamp, MC.  It's something I wouldn't expect of you....really. *G*

I can just about guarantee its the only lava lamp in the entire history of lava lamps to be used on a Black Diamond Racing Shelf. As a matter of fact, make that TWO Black Diamond Racing Shelfs, one (defunct) cartridge demagnetizer and one Teres Motor pod! Lol!
