Short answer: No. I have excellent hearing (I'm an acoustic guitarist and pianist in my "spare time"), and after we made all the updates to the K3, I burned quite a bit of lab time trying to hear what Rob was talking about. I tried *really* hard, as did my staff. We couldn't hear it. Rob is superhuman :) True, it would be possible to reclaim a bit of extra AF headroom by using an AF amp that's heavily biased (class A). But 99% of operators would not benefit, the radio would draw an extra 200-300 mA with no signal in receive mode, and the chip(s) would need fairly extensive heat sinking. Doesn't seem like a good tradeoff. (Disclaimer: I'm biased towards energy efficiency and portability.)
