[Elecraft] K3: Audio settings

[Bill]

I have been using my K3/P3 since new in early 2013. Initially, I had a 
devil of a time getting the RX audio to sound pleasing. Understand - 
that is pleasing to me. There was always a high percentage of background 
white noise.

Eventually, after a lot of experimentation, I settled on various EQ, 
AGC, ATT, RF Gain etc. All this was to make it comfortable for long-term 
armchair copy on 40, 75, and 160 meters. I also bought a pair of 
Behringer MS40 speakers to improve things.  All told, I was relatively 
pleased with the results - - - until...... I bought an Icom 7300.

The 7300 is quiet. Nearly zero background noise - signals just jump out. 
During the daytime it is close to that of 2-meter FM. Understand that my 
QTH has nearly zero noise.

Where am I going with this? Simple - I am looking for suggestions on 
eliminating the K3's white noise problem. Please do not email, as I am 
sure I am not the only K3 user similarly interested. Sharing would be great.

Thanks,
