First Integrated Amp -- help deciding
"Arny Krueger" wrote
I am seeking to replace an ailing Marantz 2325
receiver with an integrated amp.
This is a legacy 125 wpc SS receiver.
Actually what you are referencing to is a 125
watts of Music Power. RMS power per channel
is 70 watts. I assume you know the difference.

Geee-Arny, after all these years don't you think I looked it up
before posting.
Reference: Stereo/Hi-Fi Equipment directory, January 1975.
"Recognized music power is also known a dynamic power,
IHF dynamic power and probably a few other names." In the
mid 70's (subject receiver) "there were two rating systems
for Power Bandwidth. The original rating system by Institute
of Hi Fidelity and the new formed FTC rules. IHF defined it
(Power Bandwidth) as the low and high frequency extremes
at which an amplifier could produce half its rated power.
FTC defined Power Bandwidth as the range of frequencies
over which the amp can produce its stated power. But does
not specify what the Power Bandwidth must be, but only that
this term must be given along with the power rating. If we
have two 50 watt amps one with a power bandwidth of 100
Hz-10,000 Hz, and the other 20 Hz- 20,000 Hz the consumer
will realize that the latter amp has the better , broader power
response."
