There have been changes to the DSP board to allow more lows (remove a low frequency roll off) with low impedance headphones and a high cut filter has been added to remove noise from the digital to analog converter above 4.5 KHz. Those changes may help your perception of the receiver audio but I believe what you were hearing was the flat response of the K3. Unlike just about any other receiver I've tested, the K3 has an absolutely flat response 100 Hz to 4 KHz other than ripple in the first IF ("roofing") filter. Other receivers show a pronounced roll-off starting between 1000 and 1500 Hz - between 3 and 6 dB per octave. > Does anyone remember experiencing something similar with your K3 or > heard about a possible solution? It is quite easy to create that "warm" sound with the K3. Simply use the RX EQ to duplicate the roll-off you are used to hearing. Setting 1600 Hz to -3, 2400 Hz to -5 and 3200 Hz to -6 "warms up" the receive audio nicely. Use -6/-10/-12 if you want an even more "mellow" sound. 73, ...
