Are you one of those guys who can hear the difference in speaker wire?
I had a guy working for me who was a musician and audiophile who claimed he
could tell the difference. I referred him to Bob Pease.

I watched the presentation again. Yes, Rob said the K3 was fixed in 2008. He also
said the fix wasn't as good as he'd like. It didn't compete with the <0.3%
distortion of the Icom 756 Pro III. So if you look at the distortion products at
44:20, would the average amateur (like me) be able to hear that?
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.
