While I agree with the above about the Parasound A21, if the Levinson has had the caps replaced and completely serviced within the past few years, it is hands down a better sounding amp.
I was a Levinson dealer for many years and have owned a bunch of their equipment. I wasn't ever a Parasound dealer, but have owned a lot of their product also, including the A21.
Once you hear a properly working Levinson amp, it's hard to get it out of your head. They are indeed quite nice, but I agree, that they have their own sonic signature, (just like everything else).
Without knowing the provenance of the Levinson, the A21 is a safer bet.
