Sound so amazing cranked way up but my ears can't take much /of that so it is my understanding to feed them tons of power t get that performance without having to go so loud.
No, your understanding is misinformed. At lower levels you won't utilize tons of power; it simply goes unused. Also consider that at lower levels, our hearing is less sensitive to frequency extremes, so maybe try applying some loudness compensation eq.
Speaking of which, that Carver model you listed does not exist, but if you meant the TFM-24, be aware that the "TFM" stands for 'transfer function modification' or something equivalent; those amps are intentionally voiced to sound like a Marantz 8B tube amp, so they're not exactly neutral. (Since you seem to be looking for qualitative differences, that amp may be just the ticket.) I wouldn't advise bridging such amps.
