An external speaker will definitely help. But
that's not all you can do. Here's what we have
in the IC-746 FAQ on this topic.
Good luck.

Q:8.11 How does one improve the fidelity of a received signal?
Here is a checklist of several possible actions (not
in any particular order).
* Assure precise tuning
* Use a high quality external speaker or headphones
* Try to run without pre-amps or with attenuator
* Reduce the RF gain (increase AF gain to compensate)
* Set TPBT to widest bandwidth
* Use wider IF filters
* Lower level of NR (counterclockwise - to the left)
* Turn off NR
* Turn off ANF
* Turn off NB
* Set AGC to SLOW
* Be sure input power is greater than or equal to 13.5 Vdc
* Use an external AF amp via the ACC ports.
* Equalize the AF output.
