I have had this great power amplifier for many years and
for bass reproduction is outstanding. I drive my Magneplanar
Tympani IV bass panels, which have an impedance of 4 ohms,
and the amplifier puts out 400 watts per channel with this
load. Transient response is stunning and provides awesome
impact, depth and ambience that is so very real.
