They are capable of what you desire… but it is going to be a function of your other equipment. Your Bryston amp is very detailed and powerful thusly assuring good punch at the low end. But, it might be light in the midrange not giving full weight to voices and guitar. This is also partially dependent on your preamp and DAC. Hopefully those are very warm and natural sounding.
But, again… don’t judge right out of the box… they are likely to be trebly and bass shy right out of the box.
