Such hard decisions :D Anyone with some insight on Amp Selection?

You could have a nice system there if only you would ditch multi-channel HT and embrace stereo. There are lots of great stereo amps, and the same money buys a lot more quality split two ways than three, four, or five. Home Theater done right. Think about it. https://systems.audiogon.com/systems/8367

Based on what I've heard, instead of worrying about outside amps, here's my advice:

Get an Anthem MRX  720, and forego the external amps.

I think you'll find it has plenty of power and that it sounds significantly better, not to mention has a really nice ARC system.

Best,

thanks for the input but ended up getting both to test um back to back, thanks for the input but both of the suggestions end up completely scrapping things i have and ends up being a headache, all i wanted was more power and matched power to my center, believe me i would love to go down the rabbit hole, but i dont have the time nor do i want to spend the 2500 on a receiver, and the bp30's are definitely a hungry beast, from everyone ive talked to they say the more you throw at it (power) the better they sound, and i am extremely happy with the definitive bp-30s, i absolutely love them, and they sound great out of the TX-NR838 in "pure audio" mode, was just curious of the sound differences between the B&K and the adcom. I think something is wrong with the b&k because it sounds so... thin, a lot of the oomph of the speakers is gone with that amp, and its strange that the adcom gfa-5503 seems almost double the weight of the 4430, same power? so strange, but going to run the signal generator through the b&k with a dummy load, and see the sign wave, see if something funny is up, they sounded WAY different, vocals on the 4430 almost blended into the music, whereas the adcom puts vocals straight in your face, and imaging seemed better, soundstage was wider with the 4430 but again i have a funny feeling that somethings up with it, and ill find out soon when i run the tests.

Welcome. Maybe the  best thing is to decide your goals. Is it just power you want? Or do you want good sound with it?

The biggest problem with trying to mix so much equipment together is that you generally end up with a mess. Too many pieces cause too many opportunities for bad results. More power does not necessarily make for better sound. The Deftech speakers are 8 ohm & 91 db efficient. Contrary to what you have heard, these speakers shouldn’t be power hungry. My Silverlines are 93.5 db and I run them with 35wpc no problem. AAMOF, They sound better now with 35 wpc tubes than they did with 250 wpc highly regarded Solid state. Your receiver has 7 channels @ 130 wpc and yet you have 2 outboard amps. Why? Power? What good is power which is unusable/. If you must use 2 outboard amps I’d want 2 of the same. But you are getting a system way out of balance. The preamp had a LOT to do with sound. But If its just power you want, get some Berringer PA amps with 800 wpc. They are usually less expensive. Enjoy
