- Ya, big deal. Well, I've only been involved in audio professionally for 4
- years, but my background in audio goes back at least 15 yrs. I've conducted
- and been a part of many controled (by Phd psychologists) subjective tests
- over the past years, have read every AES journal back to about '72, read
- Beranek and Olson when I was 15 and basically lived and breathed audio
- since I was 10, including electronic design. If this is tootin' my own
- horn, tough shit. My point is that you tend to listen not just to
- professionals, but pro's you agree with. And I agree, I too am always hungry
- for knowledge and realize that there is much to learn from the others on
- the Net.

- Great, that counts me out!
-
- You just ain't listening, bub. I've said a zillion times that LP repro
- is inferior to CD repro in terms of MEASURED seperation,
- and dynamic range and MOST other quantifiable objective measurements.
- It is NOT inferior in terms of bandwidth. Granted, arriving at low
- distortion and wide dynamic range below 40 Hz is extremely difficult, but
- the bandwidth is not limited to below 22 kHz as per CD. Remember
- the days of SQ4? Here was an example of an LP encoded with info
- well above 20 kHz. Of course the quad systems sounded like crap at
- the time, but this just highlights LP's availability to record/replay info
- up to 40 kHz. An article was published by the AES recently concerning the
- perceptual clues offered by audio repro info above 20 kHz. Apparently,
- they found some significance. Sounds interesting, but
- I've yet to read it.

- Couldn't give a rat's ass what anyone's equipment is. People who envy
- or brag about anything monetary or material are plain suckers. I'm
- just surprised that your ears lead you to arrive at the conclusions
- they have. I'm not doubting your ears, so I doubted either your
- equipment or your criteria in judging what you here.
-

-
- Earth to Lon. I've acknowledged the technical faults of LP repro
- a few hundred times now. My point has been that the measurements
- don't tell the full story and never will. LP repro sounds
- more life-like to many folks for reasons they can't explain. You
- state that it is due to the euphonic colourations we are hearing. I don't
- buy this. If these colourations are the only reason that a system
- sounds more life-like, then there is something seriously wrong with
- the way the industry objectively specifies performance. The goal is
- life-like reproduction, and only that. I think a LOT more work
- is required in the area of defining accurate controlled subjective tests
- for audio to try and uncover these differences. A/B'ing is a waste for
- anything but glaring differences.

-
- I can't understand your inability to seperate the discussion of how
- a unit sounds subjectively, from the specs. Julian Hirsch would
- be proud.
-
- LP has many technical faults versus CD but for some reason I and MANY
- others find it to sound more life-like. To damn with the euphonic
- colourations crap. My yard-stick is LIFELIKE SOUND. NOT SPECS. What's
- your hang-up with the spec's?
