[Elecraft] A Rob Sherwood's talk in Dayton

[Luis V. Romero]

I guess we are arguing quibbles here, Don.

Of course youre correct in your comments regarding powered/unpowered 
speakers.

My ancient Yamaha YST-M101's, which are my primary station speakers on the 
line output of my K3, sound just fine to me!  But since I usually use 
headphones, I rarely listen through them anyhow.  But still, when I do 
listen without headphones, Im a happy guy (especially after the K3DSP mod 
was installed!  The buzzy flyback-transformer-like high end artifacts are 
now GONE!)

I think this entire argument is moot, but then I had to throw my hat into 
the ring... I made a pretty good living making good audio and video, and 
still do.

The K3 sound just fine to me the way it is.

Waiting for the note from the "Moderator" that we have beat this subject to 
death already.

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.
