I have a NAD C350 stereo integrated amp I use for stereo sources and
it sounds great. I have just bought the Denon 1907 receiever but still
want to run music through the stereo nad amp, and L + R movie channels
from the receiver to the same Left and Right front speakers.

Scenario ONE

Now, I could use the front L + R pre-outs of the reciever to feed the
C350 and permenantly have my speakers connected to the C350 and
disable the front L + R outputs of the receiver...


Scenario TWO

Just run one set of left and right cables from BOTH the Stereo amp AND
the receiver to the SAME terminals on the speakers, so I would get
sound from either amp at any time. (But would this cause damage with
both amps technically working 'against' each other?? They both
wouldn't be switch on at the same time, but still.....)

Scenario THREE

Run L + R wires from BOTH amps to the speakers as in scenario two, but
connected to SEPARATE CROSSOVER TERMINALS on each speaker, (the
terminals that would usually be used for bi-wiring). (But would this
cause one amp to sound 'tinny' and one to sound 'bassy'??)

Scenario FOUR

Have the C350 permanantly connected to the receiver's front L + R pre-
outs, then connected to one crossover on the speakers AND have the L +
R outputs of the receiver enabled, connected to the other crosspoint
terminals on the same speakers. (would this be classed as as an
effective way of bi-wiring, or would this setup sound odd??)

Advice much appreciated!

Cheers,
Dan
