[Elecraft] A Rob Sherwood's talk in Dayton

[Don Wilhelm]

I do not read Wayne's response that way at all.
The issue has been fixed except perhaps for all but the most discerning 
ears (audiophiles).
Wayne has 'musician ears', and would not make statements like that if 
not good to his ears.

As far as the K3 audio being better on powered external speakers than 
with un-powered speakers, think about that for a minute.  Good powered 
speakers should faithfully replicate the input signal, and that includes 
any distortion products that may be present in the input signal.

Good unpowered speakers should produce an even cleaner output because 
the input signal is not further distorted by the characteristics of the 
powered speakers.  Unfortunately, good unpowered speakers are not the 
metal cased 8 inch speakers that were available with old National or 
Hallicrafters receivers, they have a lot of bass response and color the 
signal a LOT.  They may sound good to many ears, but are not a faithful 
representation of the input signal.  Try some high efficiency good 
quality bookshelf speakers for a fair comparison.

If one wants a Hi-Fi output, then it is time to shop the audiophile 
stores for speakers rather than the consumer grade computer (and iPod) 
speakers that are commonly used.
