I also feel that K2 is easier to listen to under average conditions than K3. My K3 has the DSP board updated.
The issue could be due to 2 factors: AF distortion and AGC properties. K2 has a very sweet AGC. K3 had a very high AF distortion level that was mitigated by a series of upgrades ( at least choke and DSP board). If you read old messages, there is a message by a Russian who looked at initial IMD level (very high) and documented improvements by adding large capacitors in several places. I listened to 10m CW at WPX contest with K3 and SDRPlay, both with good speakers. The last one sounded slightly cleaner although SDRPlay would have easily overloaded with strong signals. It would be interesting to see whether K3S sounds better than K3, perhaps due to a number of small changes.
