How do you amp your system?

Assume you are ony wanting to discuss home theater sound?
I have one Denon receiver 4806 and run it five channel no subwoofer. (it has seven equal channels of amplification available)
I use Canton CD300/CD360 speakers.
No sub as i live in an apartment in an 'over 55' building.
So any noise bothering anyone else would be unwanted by ME as much as by others.

Both the receiver and speakers were bought at a dealer 'garage blowout' sale at a really low price.
They are the last home theater setup i will ever buy unless the receiver breaks...) They sound great, have wonderful clarity and are all i want.

My two channel on the other hand is one Bryston 4B-SST2 amp biwired to my Magnepan 3.6 speakers.

Home stereo. 5.1 Arcam avr handles all but sub jl audio fathom f113

Main 2 channel rig

Bi amp

Tweeters/mids. Atmasphere ma-1. Output transformer less tube mono blocks

Woofers. Qsc bluelight 360. Volume adjusted

i used to run all separates for HT but have downgraded to a receiver. either way i would always want to power all my speakers with the SAME amp/receiver to insure proper timbre matching. sub powers itself.

however, it does boil down to your level of pickiness.

Far from "prevailing wisdom," my 7 channel system evolved from my 2 channel stereo.

I started with 2 speakers driven by 2 monoblocks. Each speaker had its own subwoofer to fill out their low ends.

When I added a screen, I routed the 2 front channel outputs of the HT processor to be one of the inputs to the preamp of my stereo. And I added a center channel and 2 rear speakers driven by three other monoblocks, all sourced directly from my HT processor. These monoblocks are powerful and accurate but do not have the same class of sound as my main front channel monoblocks.

More recently, I added 2 more channels for a 7 channel HT. The 2 added speakers became the rears and the former rears became the surrounds on the sides. My rears are more efficient than the surrounds so I used a lower power stereo amp that I had bought some time ago. Fortunately, it is made by the same designer as my main front channel monoblocks, so at least it does share the same character of sound, although this is of minor importance given the sonic material usually sent to the rears.

Since my main fronts both have subwoofers and all my speakers are close to full range, I don't feel the lack of not having a dedicated subwoofer channel. When I set up my system in my HT processor, I input that there was no subwoofer for the ".1" channel.

HT set up via my trusty Acurus ACT 3 processor and ACT 5 amplifier. The ACT 5 powers all five channels with 200 watts. The sub is a powered Velodyne.

Should I not have equal power for all speakers I would then have my highest quality to power primary L & R followed by center and then surrounds.
