The quieter the amps the more I can hear into the music. The best I have heard for this is the Benchmark AHB2. It does measure quieter than all other amps.
You really want to hear into the mix put on some RAAL SR1a headphones and connect it to a AHB2(s). You will hear everything. You need some warmth up the chain for this.
