Icom 756 Pro III vs. NRD-545 vs. AOR-7030+

I've narrowed my search down to a short list of three receivers:

Icom 756 Pro III
JRC NRD-545
AOR 7030+

My primary interests are MW DXing, utilities, and general SW
listening, in that order, with SW listening a distant third.

There are no general SW dealers in my area, so I haven't seen the JRC
or the AOL, but there's a Ham Radio Outlet where I had a chance to
listen to the 756.

I've owned an NRD-525 in the past, so I know something of the
ergonomics and build quality of the NRD series, which I like, but I'm
concerned about the less than stellar reviews I've read. Most of them
complain about the audio (monkey chatter) and dynamic range issues
associated with the 18-bit A/D.

I've never seen a 7030+, but the menu-oriented operating system seems
to be a love it or hate it proposition. I've also heard of issues with
the encoders used for the main tuning knob and rotary selector wearing
out or becoming flaky with use. I've also heard that the 7030+ has
been discontinued, production stopped earlier this year, and dealers
are selling off remaining stock.

The 756 has 32-bit DSP and a 24-bit A/D, but it also has a
transmitter, which adds to the cost, making this the most expensive of
the three ($900 more than the 545 and $1200 more than the 7030+). The
sensitivity below 1500kHz is crippled, requiring a mod to disable the
attenuator and enable the pre-amp in this range. The spectrum scope is
cool, enabling you to "see" signals in a section of the band changing
in real-time.

Any advice would be appreciated.

If you can have someone resensitise the 746 Pro/756Pro III MW
spectrum, it is a receiver that is not likely to let you down. The
AR7030/AR7030+ is an excellent receiver but with potential for
improvement as the stock filters could have been a bit better. Still
the MW receiver of choice for many. The NRD-545 is beautiful to look
at. My experience was 2nd order IMD where the AR7030 would have none,
and IF filtering was not up to par ("monkey chatter") during heavy,
inside passband interference.

Let's up this a bit. How would a Icom 756 Pro III compare to a Ten Tec
RX-340 just curious?

I've not listened to an RX-340, but it's a generation older than the
756 in that it uses a 16-bit A/D rather than the 24-bit A/D in the
756. The wider A/D results in much better dynamic range on the 756.

I suspect that the ergonomics of the 340 are probably better than the
756 as it's a much bigger receiver with more room for dedicated knobs,
keypads, etc. It's also almost $1000 more expensive than the 756.
