usually the toroidal transformer will have better dynamics and handle lower impedance
loads,btl is for bridging the unused channels for the rears in case you decide to use 5.1
instead of 7.1 but warning should not use speakers below 8ohms when you use that feature.

No offense, but some of this makes no sense. Toroidal transformers have no more ability or no less ability to handle low impedence loads. That's a function of overall design. If by better dynamics, you simply mean more power, once again, that's a function of design. A 1000 watt pro amp, under normal home use will handle any dynamic peaks. And it's not likely to use a toroidal transformer.
Toroidal transformers are often used in higher end amps due to some of the factors mentioned above such as a lower hum, smaller size and less electromagnetic interference. The main downside is cost. They are more often seen in more expensive amps. I have long speculated that one of the reasons for that is that it's a selling point some people look for. But many good amps don't use them.
