I want to get a new more powerful sweet sounding amp.I doubt it the Musical Fidelity M3Si or the Parasound New Classic 200 integrated amp are more powerful sounding!
Look at the specs:
Marantz PM8006
70 Watts per channel into 8 Ohms, 100 Watts per channel into 4 Ohms
Musical Fidelity M3Si
85 Watts per channel into 8 Ohms, no rating into 4 Ohms
Parasound New Classic 200
110 Watts per channels into 4 or 8 Ohms
