Hi,

I'm trying to connect my AV receiver (Marantz SR 7300) to my high end
speakers. My question is the receiver indicates that it requires a
"minimum 8 ohms" however my speaker specs indicate 4 Ohms. Is there a
mismatch btw the speakers and the receiver? Will the Amp destroy my
speaker if I connect with this disparity? Please advise.........

You'll be fine if you don't push it too loud.

In light of the oft-cited problems sometimes encountered by low-impedance
speakers matched with certani amplifiers, I can't help whether anybody here
has
had any experience with the "Autotransformers" described in the following web
site:

If they work as claimed, this would seem to be a possible enhancement for
many
systems. As the owner of electrostatic speakers with a very difficult,
variable response curve (Martin Logan CLS IIzs with an impedance dipping
below
2 ohms at some points), I've been thinking about trying out a pair in
combination with a 4-ohm rated power amplifier (CJ Premier 11A). Even
though
I've had no major difficulties driving the speakers, I would not mind the
possibility of presenting a more benign load to the amplifier.

I've measured several hundred loudspeakers and never encountered a single load
(including Martin Logan speakers and other electrostatics) that caused problems
with the speakers driven to full output with fairly ordinary amplification. I'd
say that if you do not now have recordings that cause limiting you're still
working in the safe operating area of your electronics.
